Phenotype and susceptibility to HIV infection of CD4+ Th17 cells in the human female reproductive tract.

ABSTRACT: Prevention of sexual acquisition of HIV in women requires a substantial increase in our knowledge about HIV-target cell availability and regulation in the female reproductive tract (FRT). In this study, we analyzed the phenotype and susceptibility to HIV infection of CD4(+) T cell in the endometrium (EM), endocervix (END), and ectocervix (ECT) of the FRT. We found that T helper type 17 (Th17) cells represent a major subset in FRT tissues analyzed and that Th17 cells were the main CD4(+) T-cell population expressing C-C motif chemokine receptor 5 (CCR5) and CD90. In premenopausal women, CD4(+) T cells and Th17 cells, in particular, were significantly lower in EM relative to END and ECT. Th17 cells were elevated in EM from postmenopausal women relative to premenopausal tissues but not change
