Decreasing Sensitivity to RANTES (Regulated on Activation, Normally T Cell–Expressed and –Secreted) Neutralization of CC Chemokine Receptor 5–Using, Non–Syncytium‐Inducing Virus Variants in the Course of Human Immunodeficiency Virus Type 1 Infection

Abstract

In approximately half of human immunodeficiency virus (HIV) type 1–infected individuals, the development of CXC chemokine receptor 4–using, syncytium
