Discovery of mechanism that allows hepatitis C virus to remain in the body for decades

A study published in the Proceedings of the National Academy of Sciences (PNAS) shows that the virus blocks the actions of a specific ion channel in the cell membrane that would usually trigger apoptosis - the cell's self-destruct programme - and in doing so, has evolved another way of protecting itself from being eliminated from the body.
