Decreased susceptibility of Th1 cells to infection with primary HIV-1 isolates is associated with lower expression of CXCR4 in these cells

Folia Histochem Cytobiol. 2001;39(2):123-4.

Abstract

The HIV-1 X4-isolates replicate more efficiently in Th2 than in Th1 cells, isolated from peripheral blood lymphocytes of HIV-1 seronegative individuals. The semiquantitative RT-PCR revealed higher level of transcripts of the HIV-1 co-receptor CXCR4 in Th2 cells than in Th1 cells which might explain better replication of HIV-1 X4-isolates in these cells. Lower expression of CXCR4 in Th1 cells render these cells less susceptible to infection with HIV-1.
