Alzheimer's and CJD: PRION DISEASE

2010/4/23

New connection between Alzheimer’s and prionic illnesses discovered

Researchers at the Basque Country’s CIC bioGUNE Centre for Cooperative Research and the University of Texas Medical School at Houston (USA) have discovered the existence of a new interaction between Alzheimer’s disease and prionic pathologies, fundamentally caused by the incorrect folding of proteins involved in such illnesses. The study has also been published in the Journal of Neuroscience.

The research, led by investigators at CIC bioGUNE and the University of Texas Medical School in Houston, was based on the premise that, despite the diversity of clinical symptoms associated with illnesses related to misfolding of proteins, there exists a great similarity which suggests that many of these ailments could have a significant relation at a mechanistic molecular level.

The principal aim of the study was to analyse the interaction of the incorrect folding of proteins involved in Alzheimer’s disease and in prionic diseases.

To this end, prions were inoculated into transgenic rats used as a model for Alzheimer’s disease, in which amyloid plaques are developed

The results showed a dramatic acceleration and exacerbation in both pathologies. Concretely, the clinical signs of the prion illness in the transgenic rats appeared much more rapidly with the resulting increase in levels of incorrectly folded prionic protein in the brain. Likewise, a notable increase was observed in the deposits of the amyloid plaques so characteristic of Alzheimer’s disease.

Histological and biochemical study showed the physical association between the two incorrectly folded proteins in the brain and in vitro experiments showed that incorrect folding of the proteins may be favoured heterologically (i.e. the prionic protein favours incorrect folding of the Alzheimer plaque–forming protein) in vitro.

This suggests, as a conclusion, a deep interaction between Alzheimer’s disease and the prionic pathologies involved in the process of folding of proteins and could be a significant risk factor in the development of a second pathology.

This research may well have important implications for understanding the origin and progress of illnesses in which this phenomenon of the misfolding of proteins is involved.

The techniques used are common to both pathologies - prionic illnesses and Alzheimer’s disease -, such as the innoculation of animal models, as well as histopathological and immunohistochemical studies, biochemical studies and studies of the in vitro replication of proteins.

Prionic illnesses

Prions are pathogenic agents responsible for transmissible spongiform encephalopathies (TSEs), also known as prionic illnesses. TSEs belong to the group of mortal neurodegenerative diseases that affect human beings and animals and for which there is currently no available therapy. These conditions may have a number of different origins: hereditary, sporadic (supposedly spontaneous) and infectious.

Scrapie, the disease affecting sheep and goats, is probably the oldest prionic illness. Nevertheless, BSE (Bovine Spongiform Encephalopathy) is that which caught the attention of the public most, given its involvement in the generation of a new illness amongst humans and its proven transmission to most other species. Then there is the Creutzfeldt Jacob disease which, while having an annual rate of 1-2 cases per million inhabitants, it is still the big unknown, especially in the sporadic cases the origin of which is a mystery. In the Basque Country, a somewhat unusual situation exists, as it is concentrates many of the total number of cases throughout the world of fatal familial insomnia, a human prionic illness of genetic origin.

Prions are probably one of the most intriguing pathogenic agents in nature, as its supposed composition relating it to a single protein and the appearance of clearly differentiated strains give them an unparalleled scientific value. Their replication mechanism similar to what could well be the development of diseases such as Alzheimer’s or Parkinson’s, amongst others, make them a unique pathogen. But, if to this we add that we do not yet know what a prion is, it makes it an irresistible object for study for researchers such as those at the Prions Laboratory of at the Proteomic Unit at CIC bioGUNE.

Terry Singletary -- A retired machinist and high school dropout, Terry Singletary suffered the tragic loss of his mother to “sporadic” Creutzfeldt-Jakob disease (CJD) in 1997. Desperate to find an explanation for his mother’s death, he has devoted himself to the sad and fruitless task of connecting her death to her diet. Various reports confirm that Mrs. Singletary’s life was claimed by the most common sub-type of CJD (one that accounts for 70 percent of “sporadic” cases). Sporadic CJD, unlike its newer “variant,” is not linked to meat.

As the self-appointed international coordinator of CJD Watch, an organization he co-founded with social worker Deborah Oney, Singletary is cited in media reports as an apparent expert on tracking mad cow disease. This despite his lack of formal education and the absence for support from any credible academic, medical or scientific authority. His sensationalist allegations about the safety of U.S. beef have found their way into hundreds of newspapers and broadcasts. Singletary moderates a mad-cow discussion forum run by a vegetarian activist group; his contributions account for more than half the traffic on the “BSE-L” mailing list, which is generally read by real scientists. Animal rights activists and other food-scare artists frequently refer to him as “Dr. Terry Singletary,” apparently an honorary degree as he has yet to finish high school.

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. His specific allegations have been clearly refuted by Centers for Disease Countrol and Prevention scientists in the journal Neurology.

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.

Re: RE-Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob

disease in the United States

Email Terry S. Singeltary:

flounder@wt.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?

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...

IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;

However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).

Swiss rise in CJD raises concerns over possible BSE link [LONDON] THE LANCET

Plaque attack: Swiss patients have spongiform patterns in the brain typical of sporadic CJD. The number of people dying from Creutzfeldt-Jakob disease (CJD) has risen sharply in Switzerland -- sparking fears of a possible link with bovine spongiform encephalopathy (BSE).

BSE is thought to be the cause of a distinctive form of the brain-wasting disease known as variant CJD. The Swiss cases, in contrast, are standard 'sporadic' CJD. Each year between 1997 and 2000, no more than 11 Swiss people developed CJD. But 19 cases were reported in 2001, and seven were recorded in the first quarter of this year. This is some four times higher than the incidence elsewhere, reports a team led by Adriano Aguzzi of the University Hospital Zurich (M. Glatzel et al. Lancet 360, 139-141; 2002).

The increase could be a mere statistical blip, or it may be due to increased awareness of the disease leading to more diagnoses. More disturbing is the possibility that the cases are linked to the consumption of BSE-infected meat products -- which would mean that the BSE agent can cause two distinct forms of CJD.

Possible links between the Swiss CJD cases and BSE will now be explored by strain-typing experiments in which the disease is transmitted to mice. These tests will take at least a year to complete. "It's the best way to establish or exclude any suspected link," says Moira Bruce of the UK Institute for Animal Health's Neuropathogenesis Unit in Edinburgh.

======================================

Experiences in England and Switzerland -- two countries that discovered mad cow disease in their cattle -- have heightened concerns about the possibility some cases of sporadic CJD are due to consuming mad-cow-tainted beef. Both countries have reported increases in sporadic CJD since mad cow was first detected in British herds in 1986.

Switzerland discovered last year its CJD rate was twice that of any other country in the world. Switzerland had been seeing about eight to 11 cases per year from 1997 to 2000. Then the incidence more than doubled, to 19 cases in 2001 and 18 cases in 2002.

Mouse model sheds new light on human prion disease

Professor John Collinge said We are not saying that all or even most cases of sporadic CJD are as a result of BSE exposure, but some more recent cases may be the incidence of sporadic CJD has shown an upward trend in the UK over the last decade. While most of this apparent increase may be because doctors are now more aware of CJD and better at diagnosing it, serious consideration should be given to a proportion of this rise being BSE-related. Switzerland, which has had a substantial BSE epidemic, has noted a sharp recent increase in sporadic CJD.

CHAPTER 14

Laying Odds

Are prion diseases more prevalent than we thought?

Researchers and government officials badly underestimated the threat that mad cow disease posed when it first appeared in Britain. They didn't think bovine spongiform encephalopathy was a zoonosis-an animal disease that can sicken people. The 1996 news that BSE could infect humans with a new form of Creutzfeldt-Jakob disease stunned the world. It also got some biomedical researchers wondering whether sporadic CJD may really be a manifestation of a zoonotic sickness. Might it be caused by the ingestion of prions, as variant CJD is?

Revisiting Sporadic CJD

It's not hard to get Terry Singeltary going. "I have my conspiracy theories," admitted the 49-year-old Texan.1 Singeltary is probably the nation's most relentless consumer advocate when it comes to issues in prion diseases. He has helped families learn about the sickness and coordinated efforts with support groups such as CJD Voice and the CJD Foundation. He has also connected with others who are critical of the American way of handling the threat of prion diseases. Such critics include Consumers Union's Michael Hansen, journalist John Stauber, and Thomas Pringle, who used to run the voluminous www.madcow. org Web site. These three lend their expertise to newspaper and magazine stories about prion diseases, and they usually argue that prions represent more of a threat than people realize, and that the government has responded poorly to the dangers because it is more concerned about protecting the beef industry than people's health.

Singeltary has similar inclinations. ...

Tracking spongiform encephalopathies in North America

Xavier Bosch

"My name is Terry S Singeltary Sr, and I live in Bacliff, Texas. I lost my mom to hvCJD (Heidenhain variant CJD) and have been searching for answers ever since. What I have found is that we have not been told the truth. CWD in deer and elk is a small portion of a much bigger problem." 49-year-old Singeltary is one of a number of people who have remained largely unsatisfied after being told that a close relative died from a rapidly progressive dementia compatible with spontaneous Creutzfeldt-Jakob disease (CJD). So he decided to gather hundreds of documents on transmissible spongiform encephalopathies (TSE) and realised that if Britons could get variant CJD from bovine spongiform encephalopathy (BSE), Americans might get a similar disorder from chronic wasting disease (CWD)-the relative of mad cow disease seen among deer and elk in the USA.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

To the Editor: In their Research Letter, Dr Gibbons and colleagues1 reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD) has been stable since 1985. These estimates, however, are based only on reported cases, and do not include misdiagnosed or preclinical cases. It seems to me that misdiagnosis alone would drastically change these figures. An unknown number of persons with a diagnosis of Alzheimer disease in fact may have CJD, although only a small number of these patients receive the postmortem examination necessary to make this diagnosis. Furthermore, only a few states have made CJD reportable. Human and animal transmissible spongiform encephalopathies should be reportable nationwide and internationally.

"Löcher wie in einem Schweizer Käse" hat auch Terry Singeltary im Regelwerk der FDA ausgemacht. Der Texaner kam auf einem tragischen Umweg zu dem Thema: Nachdem seine Mutter 1997 binnen weniger Wochen an der Creutzfeldt-Jakob-Krankheit gestorben war, versuchte er, die Ursachen der Infektion aufzuspüren. Er klagte auf die Herausgabe von Regierungsdokumenten und arbeitete sich durch Fachliteratur; heute ist er überzeugt, dass seine Mutter durch die stetige Einnahme von angeblich kräftigenden Mitteln erkrankte, in denen - völlig legal - Anteile aus Rinderprodukten enthalten sind.

Von der Fachwelt wurde Singeltary lange als versponnener Außenseiter belächelt. Doch mittlerweile sorgen sich auch Experten, dass ausgerechnet diese verschreibungsfreien Wundercocktails zur Stärkung von Intelligenz, Immunsystem oder Libido von den Importbeschränkungen ausgenommen sind. Dabei enthalten die Pillen und Ampullen, die in Supermärkten verkauft werden, exotische Mixturen aus Rinderaugen; dazu Extrakte von Hypophyse oder Kälberföten, Prostata, Lymphknoten und gefriergetrocknetem Schweinemagen. In die USA hereingelassen werden auch Blut, Fett, Gelatine und Samen. Diese Stoffe tauchen noch immer in US-Produkten auf, inklusive Medizin und Kosmetika. Selbst in Impfstoffen waren möglicherweise gefährliche Rinderprodukte enthalten. Zwar fordert die FDA schon seit acht Jahren die US-Pharmaindustrie auf, keine Stoffe aus Ländern zu benutzen, in denen die Gefahr einer BSE-Infizierung besteht. Aber erst kürzlich verpflichteten sich fünf Unternehmen, darunter Branchenführer wie GlaxoSmithKline, Aventis und American Home Products, ihre Seren nur noch aus unverdächtigem Material herzustellen.

Suspect symptoms

What if you can catch old-fashioned CJD by eating meat from a sheep infected with scrapie?

28 Mar 01

Like lambs to the slaughter 31 March 2001 by Debora MacKenzie Magazine issue 2284. Subscribe and get 4 free issues. FOUR years ago, Terry Singeltary watched his mother die horribly from a degenerative brain disease. Doctors told him it was Alzheimer's, but Singeltary was suspicious. The diagnosis didn't fit her violent symptoms, and he demanded an autopsy. It showed she had died of sporadic Creutzfeldt-Jakob disease.

Most doctors believe that sCJD is caused by a prion protein deforming by chance into a killer. But Singeltary thinks otherwise. He is one of a number of campaigners who say that some sCJD, like the variant CJD related to BSE, is caused by eating meat from infected animals. Their suspicions have focused on sheep carrying scrapie, a BSE-like disease that is widespread in flocks across Europe and North America.

Now scientists in France have stumbled across new evidence that adds weight to the campaigners' fears. To their complete surprise, the researchers found that one strain of scrapie causes the same brain damage in mice as sCJD.

"This means we cannot rule out that at least some sCJD may be caused by some strains of scrapie," says team member Jean-Philippe Deslys of the French Atomic Energy Commission's medical research laboratory in Fontenay-aux-Roses, south-west of Paris. Hans Kretschmar of the University of Göttingen, who coordinates CJD surveillance in Germany, is so concerned by the findings that he now wants to trawl back through past sCJD cases to see if any might have been caused by eating infected mutton or lamb.

Scrapie has been around for centuries and until now there has been no evidence that it poses a risk to human health. But if the French finding means that scrapie can cause sCJD in people, countries around the world may have overlooked a CJD crisis to rival that caused by BSE.

Deslys and colleagues were originally studying vCJD, not sCJD. They injected the brains of macaque monkeys with brain from BSE cattle, and from French and British vCJD patients. The brain damage and clinical symptoms in the monkeys were the same for all three. Mice injected with the original sets of brain tissue or with infected monkey brain also developed the same symptoms.

As a control experiment, the team also injected mice with brain tissue from people and animals with other prion diseases: a French case of sCJD; a French patient who caught sCJD from human-derived growth hormone; sheep with a French strain of scrapie; and mice carrying a prion derived from an American scrapie strain. As expected, they all affected the brain in a different way from BSE and vCJD. But while the American strain of scrapie caused different damage from sCJD, the French strain produced exactly the same pathology.

"The main evidence that scrapie does not affect humans has been epidemiology," says Moira Bruce of the neuropathogenesis unit of the Institute for Animal Health in Edinburgh, who was a member of the same team as Deslys. "You see about the same incidence of the disease everywhere, whether or not there are many sheep, and in countries such as New Zealand with no scrapie." In the only previous comparisons of sCJD and scrapie in mice, Bruce found they were dissimilar.

But there are more than 20 strains of scrapie, and six of sCJD. "You would not necessarily see a relationship between the two with epidemiology if only some strains affect only some people," says Deslys. Bruce is cautious about the mouse results, but agrees they require further investigation. Other trials of scrapie and sCJD in mice, she says, are in progress.

People can have three different genetic variations of the human prion protein, and each type of protein can fold up two different ways. Kretschmar has found that these six combinations correspond to six clinical types of sCJD: each type of normal prion produces a particular pathology when it spontaneously deforms to produce sCJD.

But if these proteins deform because of infection with a disease-causing prion, the relationship between pathology and prion type should be different, as it is in vCJD. "If we look at brain samples from sporadic CJD cases and find some that do not fit the pattern," says Kretschmar, "that could mean they were caused by infection."

There are 250 deaths per year from sCJD in the US, and a similar incidence elsewhere. Singeltary and other US activists think that some of these people died after eating contaminated meat or "nutritional" pills containing dried animal brain. Governments will have a hard time facing activists like Singeltary if it turns out that some sCJD isn't as spontaneous as doctors have insisted.

Deslys's work on macaques also provides further proof that the human disease vCJD is caused by BSE. And the experiments showed that vCJD is much more virulent to primates than BSE, even when injected into the bloodstream rather than the brain. This, says Deslys, means that there is an even bigger risk than we thought that vCJD can be passed from one patient to another through contaminated blood transfusions and surgical instruments.

USA sporadic CJD cases rising ;

There is a growing number of human CJD cases, and they were presented last week in San Francisco by Luigi Gambatti(?) from his CJD surveillance collection.

He estimates that it may be up to 14 or 15 persons which display selectively SPRPSC and practically no detected RPRPSC proteins.

#0670: Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009

Authors: T. Singeltary; Bacliff, TX/US

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

Body: 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.

END...TSS

I look forward to further transmission studies, and a true ENHANCED BSE/atypical BSE surveillance program put forth testing all cattle for human and animal consumption for 5 years. a surveillance program that uses the most sensitive TSE testing, and has the personnel that knows how to use them, and can be trusted. I look forward to a stringent mad cow feed ban being put forth, and then strictly enforced. we need a forced, not voluntary feed ban, an enhanced feed ban at that, especially excluding blood. we need some sort of animal traceability. no more excuses about privacy. if somebody is putting out a product that is killing folks and or has the potential to kill you, then everybody needs to know who they are, and where that product came from. same with hospitals, i think medical incidents in all states should be recorded, and made public, when it comes to something like a potential accidental transmission exposure event. so if someone is out there looking at a place to go have surgery done, if you have several hospitals having these type 'accidental exposure events', than you can go some place else. it only makes sense. somewhere along the road, the consumer lost control, and just had to take whatever they were given, and then charged these astronomical prices. some where along the line the consumer just lost interest, especially on a long incubating disease such as mad cow disease i.e. Transmissible Spongiform Encephalopathy. like i said before, there is much more to the mad cow story than bovines and eating a hamburger, we must start focusing on all TSE in all species. ...TSS

TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES

1. Thank you for showing me Diana Dunstan's letter. I am glad that MRC have recognised the public sensitivity of these findings and intend to report them in their proper context. This hopefully will avoid misunderstanding and possible distortion by the media to portray the results as having more greater significance than the findings so far justify.

2. Using a highly unusual route of transmission (intra-cerebral injection) the researchers have demonstrated the transmission of a pathological process from two cases one of severe Alzheimer's disease the other of Gerstmann-Straussler disease to marmosets. However they have not demonstrated the transmission of either clinical condition as the "animals were behaving normally when killed", As the report emphasises the unanswered question is whether the disease condition would have revealed itself if the marmosets had lived longer. They are planning further research to see if the conditions, as opposed to the partial pathological process, is transmissible.

What are the implications for public health?

3. The route of transmission is very specific and in the natural state of things highly unusual. However it could be argued that the results reveal a potential risk, in that brain tissue from these two patients has been shown to transmit a pathological process, Should therefore brain tissue from such cases be regarded as potentially infective? Pathologists, morticians, neuro surgeons and those assisting at neuro surgical procedures and others coming into contact with "raw" human brain tissue could in theory be at risk. However, on a priori grounds given the highly specific route of transmission in these experiments that risk must be negligible if the usual precautions for handling brain tissue are observed.

92/11.4/1.1

4. The other dimension to consider is the public reaction. To some extent the GSS case demonstrates little more than the transmission of BSE to a pig by intra-cerebral injection. If other prion diseases can be transmitted in this way it is little surprise that some pathological findings observed in GSS were also transmissible to a marmoset. But the transmission of features of Alzheimer's pathology is a different matter, given the much greater frequency of this disease and raises the unanswered question whether some cases are the result of a transmissible prion. The only tenable public line will be that "more research is required" before that hypothesis could be evaluated. The possibility on a transmissible prion remains open. In the meantime MRC needs carefully to consider the range and sequence of studies needed to follow through from the preliminary observations in these two cases. Not a particularly comfortable message, but until we know more about the causation of Alzheimer's disease the total reassurance is not practical.

TRANSMISSION OF ALZHEIMER-TYPE PLAQUES TO PRIMATES

1. CMO will wish to be aware that a meeting was held at DH yesterday, 4 January, to discuss the above findings. It was chaired by Professor Murray (Chairman of the MRC Co-ordinating Committee on Research in the Spongiform Encephalopathies in Man), and attended by relevant experts in the fields of Neurology, Neuropathology, molecular biology, amyloid biochemistry, and the spongiform encephalopathies, and by representatives of the MRC and AFRC.

2. Briefly, the meeting agreed that:

i) Dr Ridley et als findings of experimental induction of B amyloid in primates were valid, interesting and a significant advance in the understanding of neurodegeneradve disorders;

ii) there were no immediate implications for the public health, and no further safeguards were thought to be necessary at present; and

iii) additional research was desirable, both epidemiological and at the molecular level. Possible avenues are being followed up by DH and the MRC, but the details will require further discussion.

Cellular Prion Protein Regulates the ß-Secretase Cleavage of the Alzheimer's Amyloid Precursor Protein

Hooper, NM1; Parkin, ET1; Watt, NT1; Baybutt, H2; Manson, J2; Hussain, I3; Turner, AJ1 1University of Leeds, Institute of Molecular and Cellular Biology, UK; 2Roslin Institute, Neuropathogenesis Unit, UK; 3GlaxoSmithKline, Neurodegeneration Research, UK

Background: The normal cellular function of the prion protein (PrP), the causative agent of the transmissible spongiform encephalopathies such as Creutzfeldt-Jakob disease (CJD) in humans, remains enigmatic. Several studies have reported combinations of Alzheimer's Disease (AD) and CJD neuropathology and the Val/Met129 polymorphism in the PrP gene has been identified as a risk factor for early-onset AD, leading to speculation that there may be some pathogenic connection between these two neurodegenerative conditions. The amyloid ß (Aß) peptides that cause AD are derived from the amyloid precursor protein (APP) through sequential proteolytic cleavage by the ß-secretase (BACE1) and the g-secretase complex. Aim: As both APP and PrP are cleaved by zinc metalloproteases of the ADAM family, we investigated whether PrP alters the proteolytic processing of APP. Results: Here we show that expression of PrP in SH-SY5Y cells dramatically downregulated the cleavage of APP by BACE1 and reduced the secretion of Aß peptides into the conditioned medium by >92%. Conversely, siRNA reduction of endogenous PrP in N2a cells led to an increase in secreted Aß. Furthermore, levels of Aß were significantly increased in the brains of PrP null mice as compared with wild type mice. Two mutants of PrP, PG14 and A116V, that are associated with familial human prion diseases, did not inhibit the BACE1 cleavage of APP. To investigate whether the Val/Met129 polymorphism in human PrPC would alter the production of Aß, brains from mice with the human PrP gene with MM or VV 129 genotypes were analysed. In the MM mice there was a significant increase in Aß in the brains as compared with the VV mice. In the brains of two strains (79A and 87V) of scrapie-infected mice there was a significant increase in Aß peptides as compared to uninfected mice. Conclusions: Together these data reveal a novel function for PrP in regulating the processing of APP through inhibition of BACE1. The increase in APP processing in cells expressing disease-associated forms of PrP and in scrapie-infected brains raises the possibility that the increase in Aß may contribute to the neurodegeneration observed in prion diseases.

Prion Protein Regulates the ß-Secretase Cleavage of the Alzheimer's Amyloid Precursor Protein through Interaction with Glycosaminoglycans

Griffiths, HH; Parkin, ET; Watt, NT; Turner, AJ; Hooper, NM University of Leeds, Institute of Molecular and Cellular Biology, UK

Background: Proteolytic processing of the amyloid precursor protein (APP) by ßsecretase, BACE1, is the initial step in the production of the amyloid ß (Aß) peptide which is involved in the pathogenesis of Alzheimer's disease. We have shown that the cellular prion protein (PrP) inhibits the cleavage of APP by BACE1 in cell and animal models. Aim: To investigate the mechanism by which PrP inhibits the action of BACE1. Results: Neither PrPdeltaGPI, which is not membrane attached, nor PrP-CTM, which is anchored by a transmembrane domain and is excluded from cholesterol-rich lipid rafts, reduced cleavage of APP, suggesting that to inhibit the BACE1 cleavage of APP PrP has to be localised to lipid rafts. Coimmunoprecipitation experiments demonstrated that PrP physically interacts with BACE1. However, PrP did not alter the activity of BACE1 towards a fluorogenic peptide substrate nor perturb the dimerisation of BACE1. Using constructs of PrP lacking either the octapeptide repeats or the 4 residues KKRP at the N-terminus of the mature protein (PrPdeltaN), we demonstrate that the KKRP sequence but not the octapeptide repeats, is essential for regulating the BACE1 cleavage of APP. As the KKRP sequence is known to participate in glycosaminoglycan (GAG) binding, we confirmed that PrPdeltaN did not bind to immobilised heparin. Addition of heparin to SH-SY5Y cells increased the amount of APP cleaved by BACE1 in a concentration-dependent manner and reduced the amount of BACE1 coimmunoprecipitated with PrP, suggesting that GAGs are required for PrP to interact with BACE1 and inhibit APP processing. Of a range of GAGs, including dextran sulphate, hyaluronic acid and chondroitin sulphate, investigated there was complete correlation between those that could restore BACE1 cleavage of APP in PrP expressing cells and those that bound PrP. Conclusion: These data suggest a possible mechanism by which PrP regulates the ßcleavage of APP is through the N-terminus of PrP interacting via GAGs with one or more of the heparin binding sites on BACE1 within a subset of cholesterol-rich lipid rafts, thereby restricting access of BACE1 to APP.

Furthermore, we studied how the scores differ from that of patients with Alzheimer's disease (AD). Methods:33 sCJD patients (11 with definite CJD and 22 with probable CJD) underwent neuropsychological testing with the ADAS-cog and Mini Mental State Exam (MMSE). Of these 31 were genotyped at the Codon 129 (11 Val/Val, 18 Met/Val and 2 Met/Met). The patients were matched in regards to sex and total ADAS-cog score with AD patients. The scores of the 11 ADAS-cog items were compared between the sCJD and the AD groups as well as between the sCJD-subgroups Met/Val and Val/Val and the AD group. Results:The ADAS-cog total score of the sCJD and AD groups was 22.6+/- 6.5, respectively. Regarding the single Item scores of the sCJD patient group and the AD patient group, there were statistically significant differences in the Items Constructional praxis, Word-finding difficulty in spontaneous speech and Spoken language ability. When comparing the sCJD subtypes with each other no statistically significant difference was found in the items. Conclusion: In the spee ain and constructional praxis there is indication of greater impairment in sCJD patients in general when compared with AD patients. A disturbance of the speech appears to be an important characteristic of the Met/Val and Val/Val subtypes of sCJD, and should therefore be the focus of special attention in future neuropsychological studies.

Human and Animal Food Poisoning with Mad Cow a Slow Death

an editorial by Terry S. Singeltary Sr.

HUMAN AND ANIMAL FOOD POISONING WITH MAD COW DISEASEs A SLOW DEATH

WITH all the pet food deaths mounting from tainted pet food, all the suffering not only the animals are going through, but there owners as well, why are owners of these precious animals not crying about the mad cow tainted animal carcasses they poison there animals with everyday, and have been for decades, why not an uproar about that? well, let me tell you why, they don't drop dead immediately, it's a slow death, they simply call it FELINE and or CANINE ALZHEIMER'S DISEASE, DEMENTIA OR MAD CAT/DOG DISEASE i.e. FSE and they refuse to document CSE i.e.Canine Spongiform Encephalopathy, but it's there and there is some strange pathological findings on that topic that was convientantly swept under the rug. Sadly, this happens everyday with humans, once again confidently swept under the rug as Alzheimer's and or dementia i.e. fast Alzheimer's. Who wants to spend money on an autopsy on an old dog or cat? Sadly, it's the same with humans, you get old and demented your either die or your family puts you in an old folks home and forgets about you, then you die, and again, no autopsy in most cases. Imagine 4.5 annually with Alzheimer's, with and estimated 20+ million dieing a slow death by 2050, and in reality it will most likely be much higher than that now that the blood supply has been infiltrated with the TSE agent, and we now know that blood is another route and source for this hideous disease. It's hell getting old now a days.

NOW, for the ones that don't believe me, well mad cow has been in the USA for decades undetected officially, but the late Richard Marsh documented way back, again, swept under the rug. Then in 2003 in December, the first case of BSE was finally documented, by accident. Then you had the next two cases that were documented in Texas and Alabama, but it took an act of Congress, literally, to get those finally documented, and when they were finally documented, they were atypical BSE or Bovine Amyloid Spongiform Encephalopathy (BASE), which when transmitted to humans is not vCJD or nvCJD, but SPORADIC CJD. Now you might ask yourself what about that mad cow feed ban of August 4, 1997, the year my mother died from the Heidenhain Variant of Creutzfeldt Jakob Disease (confirmed), well that ruminant to ruminant was merely a regulation on paper that nobody enforced. Just last month there was 10+ PLUS MILLION POUNDS OF BANNED BLOOD TAINTED MBM DISPERSED INTO COMMERCE, and there is no way the FDA will ever recover it. It will be fed out again. 2006 was a banner year for FDA mad cow protein fed out into commerce. Looks like 2007 will be also. Our federal Government has failed us at every corner when it comes to food safety. maybe your dog, your cat, your mom, your dad, your aunt, or your uncle, but again, who cares, there old and demented, just put them down, or put them away. It's hell getting old. ...END
