Great questions. HIV has a very specific genetic sequence (and therefore structure) of its envelop protein that binds to the CD4 receptor in a tight lock-and-key way. The relationship between your lipids and HIV viral load is not directly related to... Read more »

NIAID Scientists Identify New Cellular Receptor for HIV study. Several other immune cell receptors bind to HIV. Most important among these, the CD4 molecule, identified as an HIV receptor in 1984, functions as the principal receptor for HIV. The CCR5 and CXCR4 molecules, discovered in 1996, serve...
