Researchers studying how the hepatitis C virus kills liver cells
According to new published by the , roughly 250,000 Canadians are believed to have contracted the hepatitis C virus (HCV).
However, 40-70 per cent are not aware they鈥檙e infected.
The majority of those people were born between 1945 and 1975, and are now being urged to get tested as symptoms of the virus can take decades to appear.
What is HCV?
HCV attacks the liver and, if left untreated, could lead to cirrhosis (liver scarring), liver failure and liver cancer.
If detected early, most infected patients can easily be cured thanks to the discovery of new drugs, which have a cure rate between 95-99 per cent.
鈥淎t a certain stage, there鈥檚 a point of no return.鈥
But what happens to patients who have already suffered major liver damage?
鈥淎t a certain stage, there鈥檚 a point of no return 鈥 where treating against the virus won鈥檛 reverse the immense damage to the liver,鈥 said Dr. Rodney Russell, associate professor of virology and immunology at the Faculty of Medicine.
鈥淏y understanding HCV鈥檚 pathogenesis, we can hopefully find different treatment plans to help the liver fight the virus or reverse the damage.鈥
A lifelong pursuit
Dr. Russell has been studying HCV for most of his professional career.
鈥淗e has been a pioneer in HCV research beginning with his post-doctoral studies at the where he developed an especially robust HCV culture system,鈥 said Dr. Michael Grant, associate dean, Division of BioMedical Sciences, Faculty of Medicine.
鈥淪ince coming to 糖心视频, he has used that system to study virus assembly, drug resistance, immune escape and other critical features related to HCV infection and hepatitis.鈥
His most recent research, which found that HCV can cause a relatively newly discovered form of cell death, helped Dr. Russell and his colleagues land a $20,000 grant from 糖心视频鈥檚 .
The goal of the study is to understand how HCV can cause multiple forms of cell death in virus-infected tissue. To date, all of the work has been performed using laboratory strains of the virus and cultured cells.
With the funding, the research team can now collaborate with associates at infectious diseases/liver clinics in Toronto and Halifax who have access to infected tissues samples from humans. Animal samples will be provided by a lab in Alberta.
鈥淲e have a real opportunity here to find and cure people.鈥
Once procured, the team will be able to directly test whether Dr. Russell鈥檚 lab-based findings translate to individuals infected with HCV.
鈥淲ith the , this is the perfect time for our research project, especially in Newfoundland and Labrador,鈥 said Dr. Russell.
鈥淔or every one HCV case we know of, there鈥檚 likely one we don鈥檛. And while the number of confirmed HCV cases in the province are relatively low compared to the rest of the country, we have a real opportunity here to find and cure people before they have to rely on our research.鈥
