Study Sheds Light on How Hepatitis C Virus Evades Immune System

Hepatitis C virus (HCV) appears to disable a specific variant of the IFNL3 gene, which plays a role in the immune system's response against viral infection, explaining how people with a favorable gene pattern are more likely to clear the virus naturally or with interferon-based treatment, researchers reported in the January 2014 issue of Nature Immunology.

NS5A Inhibitor Daclatasvir Has Dual Mode of Action Against Hepatitis C Virus

The promising investigational hepatitis C virus (HCV) NS5A inhibitor daclatasvir targets 2 steps of the viral replication process, enabling very rapid HCV RNA reduction, according to a mathematical model described in the February 19, 2013, advance edition of Proceedings of the National Academy of Sciences.

IRES Inhibitor Discovery May Offer New Way to Halt Hepatitis C Replication

Researchers have discovered the structure of a molecule from a class of compounds called benzimidazoles that can attach itself to the internal ribosome entry site (IRES) in the genetic material of hepatitis C virus (HCV) and stop its replication, according to a report in the March 19, 2012, advance online edition of Proceedings of the National Academy of Sciences USA.alt

Hepatitis A Immune Response Has Implications for Hepatitis C

Hepatitis A virus appears to evade immune defenses better than hepatitis C virus, even though it only causes short-term illness. Learning about differences between viral dynamics and immune response to HAV and HCV may offer information that can inform treatment.
