Antiviral potential found in hepatitis C virus Written by Catharine Paddock PhD

Scientists have discovered how a molecule with broad-spectrum antiviral activity found inside the hepatitis C virus kills viruses but does not harm host cells - it discriminates between the molecular make-up and size of their membranes.
In a study published in the Biophysical Journal, the team shows how the molecule - called AH peptide - could have a powerful antiviral effect against viruses that have cholesterol-rich membranes, such as West Nile, dengue, measles and human immunodeficiency virus (HIV).
The researchers believe their findings could help discover new drugs that viruses will find it more difficult to resist.
