| REVELATION: The glycoprotein gp120 binds to the CD4 receptor on the T cell, causing the viral molecule to contort in a way that enables it to bind to the nearby chemokine receptor, too. This dual binding of HIV to two co-receptors triggers fusion of the viral and T cell membranes. Infection begins.|
"The virus uses a complicated set of mechanisms to target the cell and trigger a reaction to fuse the viral and cell membranes. The crystal structure doesn't completely reveal the mechanism of the conformational...
