 Soon, New Therapies to Treat Hepatitis C

A novel method to block hepatitis C virus lifecycle has been discovered by scientists.

More than 170 million people worldwide suffer from hepatitis C, the disease caused by chronic HCV infection. The disease affects the liver and is one of the leading causes of liver cancer and liver transplant around the world.

HCV is spread by blood-to-blood contact and there is no vaccine to prevent it. Current treatments for the disease are only moderately effective and can cause serious side effects.

"As HCV infects a person, it needs fat droplets in the liver to form new virus particles," said Francois Jean, Associate Professor in the Department of Microbiology and Immunology and Scientific Director of the Facility for Infectious Disease and Epidemic Research (FINDER) at UBC.

"In the process, it causes fat to accumulate in the liver and ultimately leads to chronic dysfunction of the organ."

"HCV is constantly mutating, which makes it difficult to develop antiviral therapies that target the virus itself. So we decided to take a new approach."

Jean and his team developed an inhibitor that decreases the size of host fat droplets in liver cells and stops HCV from "taking residence," multiplying and infecting other cells.

"Our approach would essentially block the lifecycle of the virus so that it cannot spread and cause further damage to the liver," said Jean.

According to Jean, HCV is one of a number of viruses that require fat to replicate in the human body. This new approach to curbing the replication of HCV could translate into similar therapies for other related re-emerging viruses that can cause serious and life threatening infections in humans, such as dengue virus.

The study has been published in the journal PLoS Pathogens.
