A team of scientists at the University of Leeds found that the protein, called Glypican-1, boosts abnormal and infectious proteins in the brain called prions, which are known to cause mad-cow disease, or bovine spongiform encephalopathy. When the researchers reduced Glypican-1 in infected mouse cells, abnormal prion levels also declined, they wrote in the online journal. Glypican-1 may act as a scaffold that brings together the two forms of the prion protein, causing normal prions to mutate into infectious ones, Nigel Hooper, one of the authors, said in a telephone interview. “It’s bringing the normal prion protein and the infectious molecule together and allowing them to interact,” said Hooper, a professor of biochemistry at the university in northern England. “The infectious molecule will then allow the normal one to convert, setting up a cascade.” In the mid-1990s, scientists found a possible link between bovine spongiform encephalopathy and a variant of the fatal human illness, Creutzfeldt-Jakob disease, which destroys brain tissue. An estimated 166 people in the U.K. may have died from variant Creutzfeldt-Jakob since 1995, according to the National Creutzfeldt-Jakob Disease Surveillance Unit in Edinburgh. Infected Animals People are believed to develop the disease by eating meat from infected animals or after transfusions of infected blood. Early symptoms include depression or psychosis, unsteadiness and involuntary movements. By the time of death, patients become immobile and mute. Researchers may be able to use the Leeds team’s finding about Glypican-1 to design drugs that disrupt the disease process and treat mad-cow disease or variant CJD, Hooper said. He said his team next plans to study the effect of removing Glypican-1 from mice. “We’re going into animal models to look at what happens if you take the Glypican-1 out,” Hooper said. The Wellcome Trust and the U.K.’s Medical Research Council funded the research published today. ### Other Botulism Lawsuits [By Heart Infant Formula tied to Botulism Outbreak spikes to 51](https://marlerclark.com/by-heart-infant-formula-tied-to-botulism-outbreak) [Botulism Outbreak at Valley Oak Food and Fuel](https://marlerclark.com/botulism-outbreak-at-valley-oak-food-and-fuel) [Marler Clark Files Two Botulism Lawsuits](https://marlerclark.com/marler-clark-files-two-botulism-lawsuits) ### Lawsuit updates about foodborne illnesses [Reactive Arthritis Lawsuit Updates](/news_events/case-news?illness=reactive-arthritis&year=all) [E. coli Lawsuit Updates](/news_events/case-news?illness=e-coli&year=all) [Guillain-Barre Syndrome Lawsuit Updates](/news_events/case-news?illness=guillain-barre-syndrome&year=all) [Salmonella Lawsuit Updates](/news_events/case-news?illness=salmonella&year=all) [Hemolytic Uremic Syndrome Lawsuit Updates](/news_events/case-news?illness=hemolytic-uremic-syndrome&year=all) [Listeria Lawsuit Updates](/news_events/case-news?illness=listeria&year=all) [Irritable Bowel Syndrome Lawsuit Updates](/news_events/case-news?illness=irritable-bowel-syndrome&year=all) [Hepatitis A Lawsuit Updates](/news_events/case-news?illness=hepatitis-a&year=all) [Norovirus Lawsuit Updates](/news_events/case-news?illness=norovirus&year=all) [Botulism Lawsuit Updates](/news_events/case-news?illness=botulism&year=all) [Campylobacter Lawsuit Updates](/news_events/case-news?illness=campylobacter&year=all) [Shigella Lawsuit Updates](/news_events/case-news?illness=shigella&year=all) [Cyclospora Lawsuit Updates](/news_events/case-news?illness=cyclospora&year=all) ### Lawsuits updates by year [Foodborne Illness Lawsuits in 1998](https://marlerclark.com/news_events/case-news?illness=all&year=1998) [Foodborne Illness Lawsuits in 1999](https://marlerclark.com/news_events/case-news?illness=all&year=1999) [Foodborne Illness Lawsuits in 2000](https://marlerclark.com/news_events/case-news?illness=all&year=2000) [Foodborne Illness Lawsuits in 2001](https://marlerclark.com/news_events/case-news?illness=all&year=2001) [Foodborne Illness Lawsuits in 2002](https://marlerclark.com/news_events/case-news?illness=all&year=2002) [Foodborne Illness Lawsuits in 2003](https://marlerclark.com/news_events/case-news?illness=all&year=2003) [Foodborne Illness Lawsuits in 2004](https://marlerclark.com/news_events/case-news?illness=all&year=2004) [Foodborne Illness Lawsuits in 2005](https://marlerclark.com/news_events/case-news?illness=all&year=2005) [Foodborne Illness Lawsuits in 2006](https://marlerclark.com/news_events/case-news?illness=all&year=2006) [Foodborne Illness Lawsuits in 2007](https://marlerclark.com/news_events/case-news?illness=all&year=2007) [Foodborne Illness Lawsuits in 2008](https://marlerclark.com/news_events/case-news?illness=all&year=2008) [Foodborne Illness Lawsuits in 2009](https://marlerclark.com/news_events/case-news?illness=all&year=2009) [Foodborne Illness Lawsuits in 2010](https://marlerclark.com/news_events/case-news?illness=all&year=2010) [Foodborne Illness Lawsuits in 2011](https://marlerclark.com/news_events/case-news?illness=all&year=2011) [Foodborne Illness Lawsuits in 2012](https://marlerclark.com/news_events/case-news?illness=all&year=2012) [Foodborne Illness Lawsuits in 2013](https://marlerclark.com/news_events/case-news?illness=all&year=2013) [Foodborne Illness Lawsuits in 2014](https://marlerclark.com/news_events/case-news?illness=all&year=2014) [Foodborne Illness Lawsuits in 2015](https://marlerclark.com/news_events/case-news?illness=all&year=2015) [Foodborne Illness Lawsuits in 2016](https://marlerclark.com/news_events/case-news?illness=all&year=2016) [Foodborne Illness Lawsuits in 2017](https://marlerclark.com/news_events/case-news?illness=all&year=2017) [Foodborne Illness Lawsuits in 2018](https://marlerclark.com/news_events/case-news?illness=all&year=2018) [Foodborne Illness Lawsuits in 2019](https://marlerclark.com/news_events/case-news?illness=all&year=2019) [Foodborne Illness Lawsuits in 2020](https://marlerclark.com/news_events/case-news?illness=all&year=2020) [Foodborne Illness Lawsuits in 2021](https://marlerclark.com/news_events/case-news?illness=all&year=2021) [Foodborne Illness Lawsuits in 2022](https://marlerclark.com/news_events/case-news?illness=all&year=2022) [Foodborne Illness Lawsuits in 2023](https://marlerclark.com/news_events/case-news?illness=all&year=2023) [Foodborne Illness Lawsuits in 2024](https://marlerclark.com/news_events/case-news?illness=all&year=2024) [Foodborne Illness Lawsuits in 2025](https://marlerclark.com/news_events/case-news?illness=all&year=2025) [Foodborne Illness Lawsuits in 2026](https://marlerclark.com/news_events/case-news?illness=all&year=2026) ##### Get Help #### Affected by an outbreak or recall?
