Fluorometric Assays for the Evaluation of Chemokine Receptor Inhibitors with Anti-HIV Activity
Introduction
In order to infect a target cell, the HIV envelope glycoprotein gp120 has to interact with both the cellular CD4 receptor and a chemokine receptor, CCR5 or CXCR4, the so-called HIV co-receptors. Several flow cytometric/fluorometric assays are developed in our lab and are very helpful in deciphering the mode of action and interaction site of several classes of HIV entry inhibitors, such as the chemokine receptor antagonists.
