Hepatitis C virus channels efforts into cell survival
Last updated: 20 August 2009
Eureka Alert
Researchers at the University of Leeds have discovered a previously unknown mechanism that allows the hepatitis C virus (HCV) 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.
Apoptosis occurs naturally in the body to allow the removal of unhealthy cells or the replacement of worn-out cells. One of the ways in which apoptosis can be triggered in a cell is to reduce its potassium levels. This can happen when the cell is exposed to oxidative stress that activates a specific ion channel (which acts as a pore in the cell membrane) causing it to open and allow out potassium ions.
However, the research team has discovered that a protein made by HCV, known as NS5A, is able to block the activation of this ion channel in liver cells, enabling these cells to resist cell death for longer.
