The factors that determine the emergence of X4 isolates in some HIV-1-infected subjects are unknown. As the level of expression of CXCR4 could favor an R5 to X4 switch, quantitative flow cytometry was used to measure CXCR4 density on CD4 T cells in 200 HIV-1-positive adults, and this was compared with CD4 counts, interleukin-7 (IL-7), and RANTES (regulated on activation, normal T expressed and secreted) plasma...
