Neurodegenerative diseases are caused by proteinaceous aggregates, usually consisting of misfolded proteins which are often typified by a high proportion of ß-sheets, which accumulate in the Central Nervous System. These diseases, including Morbus Alzheimer, Parkinson disease and Transmissible Spongiform Encephalopathies (TSEs) also termed prion disorders, afflict a substantial proportion of the human population and as such the etiology and pathogenesis of these diseases has been the focus of mounting research. Although many of these diseases arise from genetic mutations or are sporadic in nature, the possible horizontal transmissibility of neurodegenerative diseases poses a great threat to population health. In this article we discuss recent studies which suggest that the “non-transmissible” status bestowed upon Alzheimer and Parkinson diseases may need to be revised as these diseases have been successfully induced through tissue transplants. Furthermore, we highlight the importance of investigating the “natural” mechanism of prion transmission including peroral and perenteral transmission, proposed routes of gastrointestinal uptake and neuroinvasion of ingested infectious prion proteins. We examine the multitude of factors which may influence oral transmissibility and discuss the zoonotic threats which Chronic Wasting Disease (CWD), Bovine Spongiform Encephalopathy (BSE) and Scrapie may pose resulting in vCJD or related disorders. In addition, we suggest that the 37 kDa/67 kDa laminin receptor on the cell surface of enterocytes, a major cell population in the intestine, may play an important role in the intestinal pathophysiology of alimentary prion infections.

Commentary ß-amyloid oligomers and prion protein: Fatal attraction?

Volume 5, Issue 1 January/February/March 2011 Gianluigi Forloni and Claudia Balducci

The relationship between Alzheimer disease (AD) and prion-related encephalopathies (TSE) has been proposed by different points of view. Recently, the scientific attention has been attracted by the results proposing the possibility that PrPc, the protein whose pathologic form is responsible of TSE, can mediated the toxic effect of ß amyloid (Aß) oligomers. The oligomers are considered the culprit of the neurodegenerative process associated to AD, although the pathogenic mechanism activated by these small aggregates remain to be elucidated. In the initial study based on the binding screening PrPc was identified as ligand /receptor of Aß oligomers, while long term potentiation (LTP) analysis in vitro and behavioural studies in vivo, demonstrated that the absence of PrPc abolished the damage induced by Aß oligomers. The high affinity binding Aß oligomers-PrPc has been confirmed, whereas a functional role of this association has been excluded by three different studies. We approached this issue by the direct application of Aß oligomers in the brain followed by the behavioural examination of memory deficits. Our data using PrP knock-out mice suggest that Aß 1-42 oligomers are responsible for cognitive impairment in AD but PrPc is not required for their effect. Similarly, in two other studies the LTP alterations induced by Aß 1-42 oligomers was not influenced by the absence of PrP. Possible explanations of these contradictory results are discussed.

Posted On December 20, 2003 AFTER THE FIRST CASE OF MAD COW DISEASE IN THE USA WAS DOCUMENTED


" Like many activists, Singletary ignores overwhelming epidemiological and laboratory evidence that rules out a connection between sporadic CJD and beef. Relying entirely on shallow circumstantial evidence and frequent repetition of claims which have been publicly refuted as false, he also blindly insists upon a mad-cow with Alzheimer’s, Parkinson’s, and Lou Gehrig’s disease. "

SO, just who are The Center for Consumer Freedom ;

http://www.consumerfreedom.com/index.cfm



let's take a closer look shall we ;

The Center for Consumer Freedom (CCF) (formerly called the "Guest Choice Network (GCN)") is a front group for the restaurant, alcohol and tobacco industries. It runs media campaigns which oppose the efforts of scientists, doctors, health advocates, environmentalists and groups like Mothers Against Drunk Driving, calling them "the Nanny Culture -- the growing fraternity of food cops, health care enforcers, anti-meat activists, and meddling bureaucrats who 'know what's best for you.'"

CCF is registered as a tax-exempt, non-profit organization under the IRS code 501(c)(3). Its advisory board is comprised mainly of representatives from the restaurant, meat and alcoholic beverage industries.

http://www.sourcewatch.org/index.php?title=Center_for_Consumer_Freedom


http://en.wikipedia.org/wiki/Center_for_Consumer_Freedom



What Is the Center for Consumer Freedom, and Why Is It Attacking PETA?

The Center for Consumer Freedom is a nonprofit corporation run by lobbyist Richard Berman through his Washington, D.C.-based for-profit public relations company, Berman & Co. The Center for Consumer Freedom, formerly known as the Guest Choice Network, was set up by Berman with a $600,000 “donation” from tobacco company Philip Morris.

Berman arranges for large sums of corporate money to find its way into nonprofit societies of which he is the executive director. He then hires his own company as a consultant to these nonprofit groups. Of the millions of dollars “donated” by Philip Morris between the years 1995 and 1998, 49 percent to 79 percent went directly to Berman or Berman & Co.

Richard Berman is an influence peddler. He has worked out a scheme to funnel charitable donations from wealthy corporations into his own pocket. In exchange, he provides a flurry of disinformation, flawed studies, op-ed pieces, letters to the editor, and trade-industry articles, as well as access to his high-level government contacts, who are servants of the industries he represents.

Berman’s name might sound familiar. In 1995, Berman and Norm Brinker, his former boss at Steak and Ale Restaurants, were identified as the special-interest lobbyists who donated the $25,000 that disgraced then-House Speaker Newt Gingrich, who was hauled before the House Ethics Committee for influence-peddling over the money. Berman and Brinker were lobbying against raising the minimum wage.

Richard Berman is a spin doctor. For example, he has argued against a Mothers Against Drunk Driving (MADD) initiative to lower the blood alcohol content (BAC) limit for drivers by claiming that the stricter limits would punish responsible social drinkers. He has claimed that U.S. Centers for Disease Control and Prevention (CDC) warnings about salmonella-related food poisoning are just “whipping up fear over food.”

Here’s how an internal Philip Morris memo described Berman’s spin: “His proposed solution would broaden the focus of the ‘smoking issue,’ and expand into the bigger picture of over-regulation.” Smoking won’t kill you; over-regulation will.

Berman is “a one-man wrecking crew on important issues.” His approach has been described as “misleading” and “despicable.” Berman has been called “a tobacco company whore,” but he’s branched out since then.

Using “freedom of choice” as his battle cry, Berman has now taken on PETA and a number of other groups and organizations whose points of view could have an impact on the profits of his clients by waking consumers up. Berman’s Guest Choice Network has an “advisory panel” whose members in 1998 included officials representing companies ranging from Cargill Processed Meat Products and Outback Steakhouse to Minnesota Licensed Beverage Association and Sutter Home Winery. Berman’s clients are companies with vested interests in low employee wages; cheap, unhealthy restaurant-chain food, particularly meat; and tobacco, soft drink, and alcohol consumption—companies like Ruth’s Chris Steakhouse, Armour Swift, and Philip Morris, whose product line includes Kraft Foods and everything from Marlboro cigarettes to Oscar Meyer wieners and which is a major shareholder in its former subsidiary Miller Brewing, now known as SABMiller.

PETA’s recent successes in gaining fast-food industry concessions for more humane conditions for farm animals have sent ripples of fear through the food and beverage service industry. About the same time that McDonald’s buckled to PETA’s demands, Richard Berman changed his front group’s name and stepped up his attacks.

The key to Berman’s aggressive strategy is, in his own words, “to shoot the messenger ... we’ve got to attack their credibility as spokespersons,”—an interesting remark from someone whose background and funding so severely challenge his own credibility.

Email Terry S. Singeltary:

flounder@wt.net flounder9@verizon.net


I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

about sporadic CJD and BSE ;

CJD RISING SWITZERLAND

CJD is a predominantly sporadic disorder but can also occur as a dominantly inherited or infective condition. Only one of the 26 most recent confirmed cases was identified as carrying a disease related mutation of the PRNP gene, none had identifiable iatrogenic exposure, and none resembled variant CJD. Thus 25 of the 26 cases appear to be sporadic cases. Sporadic CJD is distributed worldwide with a reported incidence of about one in a million per year. Raised awareness of the disease in recent years could account for an increase in reported cases of CJD, although neither an increase in the average age of patients nor more frequent recognition of CJD amongst residents of nursing homes (where dementing illness is prevalent and misdiagnosis might be expected) were seen in the Swiss cases. Moreover, improved ascertainment as an explanation for the observed increase would imply levels of under-reporting in countries other than Switzerland, which appear implausible. The authors of the Lancet report suggest that the rise in cases might be due to some form of unidentified iatrogenic transmission or to exposure to a zoonotic source of infection, though cases do not resemble variant Creutzfeldt-Jakob disease (vCJD). The ongoing surveillance of CJD in Switzerland and the rest of Europe is essential to monitor the situation to see if this rise is sustained in Switzerland, and if a similar rise occurs in other countries (see http://www.eurocjd.ed.ac.uk).

Prion data suggest BSE link to sporadic CJD Declan Butler

Predicting the number of cases of Creutzfeldt-Jakob disease (CJD) in people as a result of transmission of bovine spongiform encephalopathy (BSE) has just got more difficult.Whereas it was thought that BSE only caused a new form of the disease called variant CJD (vCJD), a study in mice from a team led by John Collinge at University College London suggests that it may also cause a disease indistinguishable from the commonest form of classical, or 'sporadic', CJD...

Species-barrier-independent prion replication in apparently resistant species

Pertenece a: UCL University College London Eprints

Descripción: Transmission of prions between mammalian species is thought to be limited by a "species barrier," which depends on differences in the primary structure of prion proteins in the infecting inoculum and the host, Here we demonstrate that a strain of hamster prions thought to be nonpathogenic for conventional mice leads to prion replication to high levels in such mice but without causing clinical disease. Prions pathogenic in both mice and hamsters are produced. These results demonstrate the existence of subclinical forms of prion infection with important public health implications, both with respect to iatrogenic transmission from apparently healthy humans and dietary exposure to cattle and other species exposed to bovine spongiform encephalopathy prions, Current definitions of the species barrier, which have been based on clinical endpoints, need to be fundamentally reassessed.

Increased susceptibility of human-PrP transgenic mice to bovine spongiform encephalopathy following passage in sheep

http://bse-atypical.blogspot.com/2010/11/increased-susceptibility-of-human-prp.html



Seven main threats for the future linked to prions

The NeuroPrion network has identified seven main threats for the future linked to prions.

First threat

The TSE road map defining the evolution of European policy for protection against prion diseases is based on a certain numbers of hypotheses some of which may turn out to be erroneous. In particular, a form of BSE (called atypical Bovine Spongiform Encephalopathy), recently identified by systematic testing in aged cattle without clinical signs, may be the origin of classical BSE and thus potentially constitute a reservoir, which may be impossible to eradicate if a sporadic origin is confirmed.

*** Also, a link is suspected between atypical BSE and some apparently sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases constitute an unforeseen first threat that could sharply modify the European approach to prion diseases.

[9.03 am]

BELLINGER, Mr Brad, Chairman, Australian Beef Association

CARTER, Mr John Edward, Director, Australian Beef Association

CHAIR—Welcome. Would you like to make an opening statement?

Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14 December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:

You should be worried. Please let me explain. I’ve kept up with the mad cow saga for 12 years today, on December 14th 1997, some four months post voluntary and partial mad cow feed ban in the USA, I lost my mother to the Heidenhain variant Creutzfeldt-Jakob disease (CJD). I know this is just another phenotype of the infamous sporadic CJDs. Here in the USA, when USA sheep scrapie was transmitted to USA bovine, the agent was not UK BSE—it was a different strain. So why then would human TSE from USA cattle look like UK CJD from UK BSE? It would not. So this accentuates that the science is inconclusive still on this devastating disease. He goes on to state:

The OIE— the International Organisation of Epizootics, the arm of the WTO— is a failed global agent that in my opinion is bought off via bogus regulations for global trade and industry reps. I have done this all these years for nothing but the truth. I am a consumer, I eat meat, but I do not have to sit idly by and see the ignorance and greed of it all while countless numbers of humans and animals are being exposed to the TSE agents. All the USA is interested in is trade, nothing else matters.

Even Dr Stanley Prusiner, who incidentally won the Nobel Health Prize in 1997 for his work on the prion—he invented the word ‘prion’, or it came from him—states:

beef trade talks to continue but curbs to remain: Japan

http://bse-atypical.blogspot.com/2010/04/us-beef-trade-talks-to-continue-but.html



Even McDonald’s, an international business symbolic of American culture, advertises that it uses only “pure Australian beef” in South Korea. Burger King announced that it only uses beef from Australia and New Zealand. Why? Even famous brands like McDonald’s cannot survive if they are perceived as using unsafe ingredients. They know that Koreans still do not trust the safety of American beef and must distance their brands from American beef.

Therefore the U.S. should aim to export only the best quality beef to Korea and regain the Korean people’s trust. Regaining Koreans’ confidence in U.S. beef will be a long-term gain for many American industries seeking to access the 12th largest economy in the world.

How will we know that U.S. beef has regained trust in South Korea? When McDonald’s in South Korea announces it uses “pure American beef.”

McDonald's and USA BSE aka mad cow disease McDonald's AND Seriologicals USA NOT PROTECTED FROM MAD COW

http://bse-atypical.blogspot.com/2010/11/mcdonalds-and-usa-bse-aka-mad-cow.html



Atypical BSE in Cattle

BSE has been linked to the human disease variant Creutzfeldt Jakob Disease (vCJD). The known exposure pathways for humans contracting vCJD are through the consumption of beef and beef products contaminated by the BSE agent and through blood transfusions. However, recent scientific evidence suggests that the BSE agent may play a role in the development of other forms of human prion diseases as well. These studies suggest that classical type of BSE may cause type 2 sporadic CJD and that H-type atypical BSE is connected with a familial form of CJD.

To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

14th ICID International Scientific Exchange Brochure -

Final Abstract Number: ISE.114

Session: International Scientific Exchange

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

T. Singeltary

Bacliff, TX, USA

Background:

An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.

Methods:

12 years independent research of available data

Results:

I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.

Conclusion:

I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE. In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.

That assumption would be wrong. I encourage you to read the whole article and call me if you have questions or need more clarification (phone: 404-639-3091). Also, we do not claim that "no-one has ever been infected with prion disease from eating venison." Our conclusion stating that we found no strong evidence of CWD transmission to humans in the article you quoted or in any other forum is limited to the patients we investigated.

Chronic Wasting Disease: Surveillance Update North America: February 2010

There are now two documented strains of CWD, and science is showing that indeed CWD could transmit to humans via transmission studies ;

PPo3-7:

Prion Transmission from Cervids to Humans is Strain-dependent

Qingzhong Kong, Shenghai Huang,*Fusong Chen, Michael Payne, Pierluigi Gambetti and Liuting Qing Department of Pathology; Case western Reserve University; Cleveland, OH USA *Current address: Nursing Informatics; Memorial Sloan-Kettering Cancer Center; New York, NY USA

Key words: CWD, strain, human transmission

Chronic wasting disease (CWD) is a widespread prion disease in cervids (deer and elk) in North America where significant human exposure to CWD is likely and zoonotic transmission of CWD is a concern. Current evidence indicates a strong barrier for transmission of the classical CWD strain to humans with the PrP-129MM genotype. A few recent reports suggest the presence of two or more CWD strains. What remain unknown is whether individuals with the PrP-129VV/MV genotypes are also resistant to the classical CWD strain and whether humans are resistant to all natural or adapted cervid prion strains. Here we report that a human prion strain that had adopted the cervid prion protein (PrP) sequence through passage in cervidized transgenic mice efficiently infected transgenic mice expressing human PrP, indicating that the species barrier from cervid to humans is prion strain-dependent and humans can be vulnerable to novel cervid prion strains. Preliminary results on CWD transmission in transgenic mice expressing human PrP-129V will also be discussed.

PPo2-27:

Generation of a Novel form of Human PrPSc by Inter-species Transmission of Cervid Prions

Prion diseases are infectious neurodegenerative disorders affecting humans and animals that result from the conversion of normal prion protein (PrPC) into the misfolded and infectious prion (PrPSc). Chronic wasting disease (CWD) of cervids is a prion disorder of increasing prevalence within the United States that affects a large population of wild and captive deer and elk. CWD is highly contagious and its origin, mechanism of transmission and exact prevalence are currently unclear. The risk of transmission of CWD to humans is unknown. Defining that risk is of utmost importance, considering that people have been infected by animal prions, resulting in new fatal diseases. To study the possibility that human PrPC can be converted into the infectious form by CWD PrPSc we performed experiments using the Protein Misfolding Cyclic Amplification (PMCA) technique, which mimic in vitro the process of prion replication. Our results show that cervid PrPSc can induce the pathological conversion of human PrPC, but only after the CWD prion strain has been stabilized by successive passages in vitro or in vivo. Interestingly, this newly generated human PrPSc exhibits a distinct biochemical pattern that differs from any of the currently known forms of human PrPSc, indicating that it corresponds to a novel human prion strain. Our findings suggest that CWD prions have the capability to infect humans, and that this ability depends on CWD strain adaptation, implying that the risk for human health progressively increases with the spread of CWD among cervids.



PPo2-7:

Biochemical and Biophysical Characterization of Different CWD Isolates

Martin L. Daus and Michael Beekes Robert Koch Institute; Berlin, Germany

Key words: CWD, strains, FT-IR, AFM

Chronic wasting disease (CWD) is one of three naturally occurring forms of prion disease. The other two are Creutzfeldt-Jakob disease in humans and scrapie in sheep. CWD is contagious and affects captive as well as free ranging cervids. As long as there is no definite answer of whether CWD can breach the species barrier to humans precautionary measures especially for the protection of consumers need to be considered. In principle, different strains of CWD may be associated with different risks of transmission to humans. Sophisticated strain differentiation as accomplished for other prion diseases has not yet been established for CWD. However, several different findings indicate that there exists more than one strain of CWD agent in cervids. We have analysed a set of CWD isolates from white-tailed deer and could detect at least two biochemically different forms of disease-associated prion protein PrPTSE. Limited proteolysis with different concentrations of proteinase K and/or after exposure of PrPTSE to different pH-values or concentrations of Guanidinium hydrochloride resulted in distinct isolate-specific digestion patterns. Our CWD isolates were also examined in protein misfolding cyclic amplification studies. This showed different conversion activities for those isolates that had displayed significantly different sensitivities to limited proteolysis by PK in the biochemical experiments described above. We further applied Fourier transform infrared spectroscopy in combination with atomic force microscopy. This confirmed structural differences in the PrPTSE of at least two disinct CWD isolates. The data presented here substantiate and expand previous reports on the existence of different CWD strains.

ADAPTATION OF CHRONIC WASTING DISEASE (CWD) INTO HAMSTERS, EVIDENCE OF A WISCONSIN STRAIN OF CWD

Chad Johnson1, Judd Aiken2,3,4 and Debbie McKenzie4,5 1 Department of Comparative Biosciences, University of Wisconsin, Madison WI, USA 53706 2 Department of Agriculture, Food and Nutritional Sciences, 3 Alberta Veterinary Research Institute, 4.Center for Prions and Protein Folding Diseases, 5 Department of Biological Sciences, University of Alberta, Edmonton AB, Canada T6G 2P5

The identification and characterization of prion strains is increasingly important for the diagnosis and biological definition of these infectious pathogens. Although well-established in scrapie and, more recently, in BSE, comparatively little is known about the possibility of prion strains in chronic wasting disease (CWD), a disease affecting free ranging and captive cervids, primarily in North America. We have identified prion protein variants in the white-tailed deer population and demonstrated that Prnp genotype affects the susceptibility/disease progression of white-tailed deer to CWD agent. The existence of cervid prion protein variants raises the likelihood of distinct CWD strains. Small rodent models are a useful means of identifying prion strains. We intracerebrally inoculated hamsters with brain homogenates and phosphotungstate concentrated preparations from CWD positive hunter-harvested (Wisconsin CWD endemic area) and experimentally infected deer of known Prnp genotypes. These transmission studies resulted in clinical presentation in primary passage of concentrated CWD prions. Subclinical infection was established with the other primary passages based on the detection of PrPCWD in the brains of hamsters and the successful disease transmission upon second passage. Second and third passage data, when compared to transmission studies using different CWD inocula (Raymond et al., 2007) indicate that the CWD agent present in the Wisconsin white-tailed deer population is different than the strain(s) present in elk, mule-deer and white-tailed deer from the western United States endemic region.

yep, but the SECOND passage was especially a doozy, and remember, oral transmission will take much longer than intracerebral route, and we now have two documented strains of cwd i.e. the regular strain of cwd (whatever the hell that means), and the Wisconsin strain, with probably more in the pipeline. NOW, THE MILLION DOLLAR QUESTION, WAS THE WISCONSIN CWD STRAIN INCLUDED IN THE ORAL TRANSMISSION STUDY ?

also, cwd has been transmitted to deer mice (Peromyscus maniculatus), white-footed mice (P. leucopus), meadow voles (Microtus pennsylvanicus), and red-backed voles (Myodes gapperi).

Title: Experimental Second Passage of Chronic Wasting Disease (Cwd(mule Deer)) Agent to Cattle

Authors

Hamir, Amirali Kunkle, Robert Miller, Janice - ARS RETIRED Greenlee, Justin Richt, Juergen

Submitted to: Journal of Comparative Pathology Publication Type: Peer Reviewed Journal Publication Acceptance Date: July 25, 2005 Publication Date: January 1, 2006 Citation: Hamir, A.N., Kunkle, R.A., Miller, J.M., Greenlee, J.J., Richt, J.A. 2006. Experimental second passage of chronic wasting disease (CWD(mule deer)) agent to cattle. Journal of Comparative Pathology. 134(1):63-69.

Interpretive Summary: To compare the findings of experimental first and second passage of chronic wasting disease (CWD) in cattle, 6 calves were inoculated into the brain with CWD-mule deer agent previously (first) passaged in cattle. Two other uninoculated calves served as controls. Beginning 10-12 months post inoculation (PI), all inoculates lost appetite and weight. Five animals subsequently developed clinical signs of central nervous system (CNS) abnormality. By 16.5 months PI, all cattle had been euthanized because of poor prognosis. None of the animals showed microscopic lesions of spongiform encephalopathy (SE) but the CWD agent was detected in their CNS tissues by 2 laboratory techniques (IHC and WB). These findings demonstrate that inoculated cattle amplify CWD agent but also develop clinical CNS signs without manifestation of microscopic lesions of SE. This situation has also been shown to occur following inoculation of cattle with another TSE agent, namely, sheep scrapie. The current study confirms previous work that indicates that the diagnostic tests currently used for confirmation of bovine spongiform encephalopathy (BSE) in the U.S. would detect CWD in cattle, should it occur naturally. Furthermore, it raises the possibility of distinguishing CWD from BSE in cattle due to the absence of microscopic lesions and a unique multifocal distribution of PrPres, as demonstrated by IHC, which in this study, appears to be more sensitive than the WB. Technical Abstract: To compare clinicopathological findings of first and second passage of chronic wasting disease (CWD) in cattle, a group of calves (n=6) were intracerebrally inoculated with CWD-mule deer agent previously (first) passaged in cattle. Two other uninoculated calves served as controls. Beginning 10-12 months post inoculation (PI), all inoculates lost appetite and lost weight. Five animals subsequently developed clinical signs of central nervous system (CNS) abnormality. By 16.5 months PI, all cattle had been euthanized because of poor prognosis. None of the animals showed microscopic lesions of spongiform encephalopathy (SE) but PrPres was detected in their CNS tissues by immunohistochemistry (IHC) and Western blot (WB) techniques. These findings demonstrate that intracerebrally inoculated cattle not only amplify CWD PrPres but also develop clinical CNS signs without manifestation of morphologic lesions of SE. This situation has also been shown to occur following inoculation of cattle with another TSE agent, scrapie. The current study confirms previous work that indicates the diagnostic techniques currently used for confirmation of bovine spongiform encephalopathy (BSE) in the U.S. would detect CWD in cattle, should it occur naturally. Furthermore, it raises the possibility of distinguishing CWD from BSE in cattle due to the absence of neuropathologic lesions and a unique multifocal distribution of PrPres, as demonstrated by IHC, which in this study, appears to be more sensitive than the WB.

Alzheimer's Dementia U.S. News Man, 88, kills wife in Calif. nursing home

U.S. News Man, 88, kills wife in Calif. nursing home

Published: Nov. 22, 2010 at 9:57 AM

SEAL BEACH, Calif., Nov. 22 (UPI) -- A man who had long cared for his ailing wife, whose "mind was gone," ended 70 years of marriage by shooting her in a nursing home, their daughter said.

Roy Charles Laird, 88, killed his wife Clara, 86, Sunday with a single gunshot to the head at the Country Villa Health Care Center in Seal Beach, police told the Los Angeles Times.

"It was a mercy killing," said their daughter, Kathy Palmateer, 68. "Her mind was gone."

As Clara Laird declined steadily from dementia over five years, her husband cared for her himself at home until three months ago. He would visit her at the nursing home three times a day, spoon-feeding her at each meal, friends and family said.

Around noon Sunday, a single gunshot was heard at the nursing home. Within minutes, police surrounded it and called in backup.

"We didn't know if we had a shooter or not," said Seal Beach police Sgt. Steve Bowles.

Police found Clara Laird dead in her bed and her husband in the hallway. He followed them into her room, took a .38-caliber revolver out of his pocket and calmly set it on a table, Bowles said.

Laird was arrested on suspicion of murder.

God bless his soul, and may they both rest in peace. he will not last long now, because his soul died too. Alzheimer's, Prion disease, Dementia, and all neurological disease are truly a nightmare. If you have never witnessed the demise and death of a person from this, long term, or short, then you really should not persecute this man.

AS a layperson, and as someone that has witnessed the demise and death of a close loved one to hvCJD and Alzheimer's, it is a cruel, brutal death, and the loved ones and friends that care for them, a part of them die as well, and you never forget.

I do not condone, or approve of this man choice to end the brutal clutches of Alzheimer's that had a hold of his wife, but i have been there before. ...

On July 22, 2009, Senator Barbara Mikulski (D-MD) introduced S. 1492, the Alzheimer’s Breakthrough Act. This bill would increase Alzheimer’s research funding through the National Institutes of Health (NIH) from $400 million to $2 billion in 2010. The legislation would also establish a National Summit on Alzheimer’s disease to coordinate researchers, policymakers and public health professionals. Additionally, it would expand the Alzheimer’s State Matching Grant Program as well as the Alzheimer’s 24/7 call center to provide updated resources and tools for caregivers, family members and those affected in a multilingual capacity.

The Alzheimer’s Breakthrough Act has been referred to the Senate Committee on Health, Education, Labor and Pensions, on which I do not serve. Should this legislation come before the full Senate for a vote, you may be certain I will keep your views in mind.

I am a strong proponent of biomedical research to help discover the causes of and cures for diseases like Alzheimer’s. I recently supported an amendment introduced by Senator Tom Harkin (D-IA) to H.R. 1, America’s Recovery and Reinvestment Act, which appropriated $6.5 billion to the NIH.

As a member of the Senate Appropriations Committee, I worked to include more than $945 million for chronic disease prevention, health promotion and genomics in the FY 2010 Labor, Health and Human Services, Education, and Related Agencies Appropriations Bill (H.R. 3293). This funding is almost a $65 million increase from FY 2009 and includes $2 million specifically for Alzheimer's disease. I also worked with the Committee to include approximately $1.1 billion for the National Institute on Aging (NIA) and strongly urged the NIA to devote more funding to clinical studies and the renewal of the Alzheimer's Disease Neuroimaging Initiative. H.R. 3293 was passed by the Senate Appropriations Committee on July 30, 2009, and is now ready to be considered by the full Senate.

I appreciate hearing from you, and I hope that you will not hesitate to contact me on any issue that is important to you.

Sincerely,
Kay Bailey Hutchison

The intracerebral injection of â-amyloid–containing brain extracts can induce cerebral â-amyloidosis and associated pathologies in susceptible hosts. Here, we found that intraperitoneal inoculation with â-amyloid–rich extracts induced â-amyloidosis in the brains of â-amyloid precursor protein transgenic mice after prolonged incubation times.

Intracerebral (i.c.) inoculation with minute amounts of brain extract containing misfolded ß-amyloid (Aß) from patients with Alzheimer’s Disease or from amyloid-bearing ß-amyloid precursor protein (APP) transgenic (tg) mice induces cerebral ß-amyloidosis and related pathologies in APP tg mice in a time- and concentration-dependent manner (1). However, oral, intravenous, intraocular, or intranasal inoculations have failed to induce cerebral ß-amyloidosis in APP tg hosts (2). These findings suggest that Aß-containing brain material in direct contact with the brain can induce cerebral ß-amyloidosis, but that, unlike prions, either the inducing agent is not readily conveyed from peripheral sites to the brain, or a higher concentration or longer incubation period is required for peripherally delivered Aß seeds.

Intraperitoneal (i.p.) administration of prion-rich material is more efficient at transmitting prion disease than is oral administration (3, 4). To test whether i.p. inoculation of Aß- rich material might similarly trigger Aß misfolding and deposition in the brain, we administered two i.p. injections (100 µl each, 1 week apart) of Aß-laden (10-20 ng/µl) brain extract from aged APP23 tg mice (Tg extract) to a cohort of young (2-month-old) female APP23 tg mice (5). After a 7-month incubation period, cerebral ß-amyloidosis was robustly induced in all i.p. inoculated mice compared to untreated littermate controls (Fig. 1). To confirm this finding, we inoculated a second cohort of 2-month-old female APP23 mice with a different batch of Tg brain extract in another laboratory (cohort 2: Tübingen, vs. cohort 1: Basel). After 6–7 months, mice injected i.p. with the Tg extract exhibited robust cerebral ß-amyloidosis, whereas i.p. inoculation with phosphate-buffered saline (PBS) or brain extract from agematched, non-tg wildtype mice (Wt extract) was ineffective (Fig. 1).

Induced ß-amyloidosis was strongest in the anterior and entorhinal cortices with additional deposition in the hippocampus, resembling the regional development of endogenous ß-amyloidosis in aged APP23 mice (6). However, whereas normal aged APP23 mice manifest mostly parenchymal deposits, the induced ß-amyloid in i.p. seeded mice was predominantly associated with blood vessels (cerebral ß-amyloid angiopathy [Aß-CAA]), often with massive spreading into the neighboring brain parenchyma (Fig. 1). The presence of Aß was confirmed by immunoblotting, and amyloid fibrils were evident ultrastructurally; in addition, the induced ß-amyloidosis was linked to gliosis, hyperphosphorylated tau, and other associated pathologies (Fig. 2), reminiscent of the cerebral ß-amyloid deposition in aged APP23 mice (6, 7).

To compare the efficiency and time course of i.p. versus i.c. inoculation, 2-month-old female APP23 mice were inoculated either i.p. (2 x 100 µl) or i.c. (2.5 µl into the hippocampus) with Tg extract, and then analyzed 4 months later. No cerebral ß-amyloid induction was found in any of the 4 i.p. inoculated mice, while all 6 i.c. inoculated mice revealed ß-amyloid induction identical to that previously reported (1, 2). From this observation, together with previous time course and 1:20 dilution experiments for i.c. inoculations (1), we estimate that i.p. inoculations with 103-fold more Aß take 2–5 months longer to induce cerebral ß-amyloidosis than do i.c. inoculations.

The replication of peripherally applied prions and their translocation into the central nervous system depend on hematopoietic and stromal immune cells, in combination with sympathetic innervation of abdominal lymphoid organs (8). Both activation of the immune system and chronic inflammation promote prion replication (9, 10). To assess the immune response to Aß-rich brain extracts, additional APP23 mice were given single i.p. injections of 200 µl Tg or Wt extract and sacrificed 1 hour, 1 week, or 1 month postinjection (5). An acute immune activation to the injected brain material was indicated by transient increases in plasma chemokines and cytokines (IL6, IL10, TNF-a, MCP-1, MIP-1ß) in both Tg and Wt extract-inoculated mice after 1 hour, with IL-6 still mildly elevated in Tg extract-injected mice 1 week post-inoculation (fig. S1). However, no signs of chronic inflammation in various peripheral organs (e.g. liver,pancreas, kidney, lung) or serum anti-Aß antibody titers were found in any mice investigated at 1 or 7 months postseeding (5). Moreover, no ß-amyloid deposition was found in any of the peripheral tissues at any time point studied.

Thus, like prion disease, cerebral ß-amyloidosis can be seeded in the brain by homologous protein aggregates delivered into the peritoneal cavity, although the i.p. route required more time and was less efficient than was direct injection into the brain (1, 2). The amyloid-inducing factor in the Tg extract is probably a species of misfolded Aß that is generated in its most effective form or composition in vivo (1). Because the expression of tg (human) APP is restricted to the nervous system in APP23 mice (7), in this model it is likely that the seed carried to the brain was the injected material itself, rather than Aß aggregates that were first amplified in peripheral tissues.

There is now persuasive evidence that the aggregation of Aß is a key pathogenic feature of AD and Aß-CAA (11–14), although the majority of these cases are initiated by unknown causes. The possibility that mechanisms exist allowing for the transport of Aß aggregates (and possibly other seeds) from the periphery to the brain justifies further studies to better understand the cellular and molecular origin of these diseases and to clarify the basis of infectious vs. non-infectious proteopathies (15, 16).

(C and D) Most induced ß-amyloid was vascular (Aß-CAA), with Aß-immunoreactivity extending into the brain parenchyma (arrows). Amyloid-laden vessels were congophilic (red in D; birefringent under crosspolarized light, insert) and often were surrounded by diffuse, Congo red-negative Aß deposits (arrowheads). (E and F) Analysis of the entire neocortex for Aß-CAA frequency (indicated are all three [I-III] CAA severity grades [5]), and for total Aß load in Tg extract-inoculated mice compared to control (Ctr) mice. Cohort 1 consisted of 6 Tg extractinoculated mice vs. 7 untreated control mice. Aß-CAA: t(11) = 6.78 (all severity grades combined), ***P < 0.0001; Aß load: t(11) = 8.79, ***P < 0.0001. Cohort 2 consisted of 5 Tg extract-inoculated mice vs. 5 Wt extract-inoculated mice and 4 PBS-injected mice. These latter 2 (control) groups did not differ significantly, and were combined for analysis. Aß-CAA: t(12) = 7.79, ***P < 0.0001; Aß load t(12) = 2.71, *P < 0.05. The occasional parenchymal Aß-deposits in control mice are normal for 9-month-old APP23 mice. Indicated are means ±SEM. Scale bars: 200 µm (A,B); 50 µm (C,D).

Simultaneous Onset of Alzheimer's Disease in a Husband and Wife in Their Mid Fifties: What do We Really Know?


Jonathan Heath1, Lindsay Goicochea2, Mark Smith3, Rudy Castellani4. 1Department of Pathology, University of Maryland; 2University; 3Case Western Reserve University; 4University of Maryland, Baltimore, Maryland

Whereas the genetic factors influencing the development and expression of Alzheimer's disease are well characterized, environmental factors are currently thought to play a marginal role. Such factors as prior closed head injury, post-menopausal estrogen deficiency, aluminum exposure, smoking, diabetes, atherosclerotic cardiovascular disease, and diet, among others, confer only a modest increased risk if any, and are only tangentially considered in the major pathogenic cascades that are presently hypothesized. We present the simultaneous onset of Alzheimer's disease in a husband and wife, with both subjects experiencing cognitive dysfunction within the same month. Both subjects were in their mid-fifties at the time of presentation, both subjects showed progressively neurological decline with prominent memory loss, both subjects experienced myoclonus late in their disease course prompting referral to the National Prion Disease Pathology Surveillance Center, and both subjects expired 12 years after onset, within two months of each other. Review of the family pedigree revealed no family history of dementia or other neurologic illnesses in multiple first degree relatives. The only historical finding of note was that both subjects had moved out of their home briefly while it was being remodeled, and both became symptomatic shortly after moving back in. At autopsy, the subjects had classic advanced Alzheimer's disease, with Braak stage VI pathology that was otherwise identiical in quantity and distribution of amyloid-beta, cerebral amyloid angiopathy, and neurofibrillary degeneration. While no specific toxin or other environmental cause was discerned, these two cases raise the issue of epigenetic factors in Alzheimer's disease that may be more robust than current literature indicates.

A 53-year-old man died of sporadic Creutzfeldt-Jakob disease (CJD) after a 1.5-year clinical course. Four and a half years later, his then 55-year-old widow died from CJD after a 1-month illness. Both patients had typical clinical and neuropathologic features of the disease, and pathognomonic proteinase-resistant amyloid protein ("prion" protein, or PrP) was present in both brains. Neither patient had a family history of neurologic disease, and molecular genetic analysis of their PrP genes was normal. No medical, surgical, or dietary antecedent of CJD was identified; therefore, we are left with the unanswerable alternatives of human-to-human transmission or the chance occurrence of sporadic CJD in a husband and wife.

Research Lead: Dr. David Westaway, University of Alberta

Project: "Extending the spectrum of Prionopathies to Amyotrophic Lateral Sclerosis and Autism"

This project proposes to link the chemistry of the prion protein to the new territory of other nervous system diseases, such as ALS (Lou Gehrig's disease) and the socialization disorder autism-diseases which are at least one thousand times more common than prion diseases. It is believed that a different type or prion protein may operate in other types of brain diseases, which could lead to new ways of thinking about incurable disorders. The project will create changes in the amounts of the various forms of the new membrane protein, and then perform an array of analyses on the behavior and nervous system transmission of laboratory mice. Nervous transmission by electrical impulse can be measured in isolated brain cells, a system that is also convenient to study the effect of stress by adding small amounts of toxins to the fluids bathing the cultures. By these means, the project aims to extend the boundaries of what is considered "prion disease."

Unfolding the Prion Mystery Building and Growing Research Expertise in Alberta Year 4 2008-2009 Annual Report

Dr. David Westaway, University of Alberta Extending the spectrum of prionopathies to amyotrophic lateral sclerosis (ALS) and autism Dr. Westaway’s study aims to extend the boundaries of what is considered prion disease. His project takes the chemistry of the prion protein into the territory of nervous system diseases such as ALS (Lou Gehrig’s disease) and socialization disorder diseases such as autism. These brain diseases are at least 1,000 times more common than diseases currently accepted as prion related. Dr. Westaway hypothesizes that a different type of protein misfolding may operate in brain diseases such as Lou Gehrig’s and autism. This type of protein misfolding may occur in response to stresses in the brain. Unlike misfolded prions, other misfolded proteins may be noninfectious and not viable outside of the affected animal. Dr. Westaway’s research team will investigate these hypotheses by inducing changes in the brain cells of laboratory mice, measuring the resulting electrical impulses in the animals’ nervous systems and analyzing the effect on behaviour. Because nervous transmission by electrical impulse can be measured in isolated brain cells, adding small amounts of toxins to the fluids bathing the cell cultures will make it possible to study the effect of stress. The results could lead to new ways of thinking about nervous system disorders.

ONE FINAL COMMENT PLEASE, (i know this is long Dr. Freas but please bear with me)

THE USA is in a most unique situation, one of unknown circumstances with human and animal TSE. THE USA has the most documented TSE in different species to date, with substrains growing in those species (BSE/BASE in cattle and CWD in deer and elk, there is evidence here with different strains), and we know that sheep scrapie has over 20 strains of the typical scrapie with atypical scrapie documented and also BSE is very likely to have passed to sheep. all of which have been rendered and fed back to animals for human and animal consumption, a frightening scenario. WE do not know the outcome, and to play with human life around the globe with the very likely TSE tainted blood from the USA, in my opinion is like playing Russian roulette, of long duration, with potential long and enduring consequences, of which once done, cannot be undone.

These are the facts as i have come to know through daily and extensive research of TSE over 9 years, since 12/14/97. I do not pretend to have all the answers, but i do know to continue to believe in the ukbsenvcjd only theory of transmission to humans of only this one strain from only this one TSE from only this one part of the globe, will only lead to further failures, and needless exposure to humans from all strains of TSE, and possibly many more needless deaths from TSE via a multitude of proven routes and sources via many studies with primates and rodents and other species. ...
