HIV takes double hit before entry

Abstract

In the absence of a vaccine or a cure, identification of novel HIV-1 inhibitors remains important. A paper in Retrovirology describes a rationally designed bi-specific protein that irreversibly damages the viral envelope glycoprotein complex via a two-punch mechanism. In contrast to traditional drugs that inhibit essential steps in the viral life cycle at the cell surface or in the infected cells, this inhibitor cripples free virus in the absence of cells.See research article: http://www.retrovirology.com/content/9/1/104. © 2012 Sanders; licensee BioMed Central Ltd.
