HIV Type 1 Infection in Women: Increased Transcription of HIV Type 1 in Ectocervical Tissue Explants

Abstract

This is, to our knowledge, the first study to compare ectocervix and endometrium in a tissue explant model of HIV-1 infection and to demonstrate greater HIV-1 transcription in the ectocervix. Our results suggest that the ectocervix is more conducive to HIV-1 replication than is the endometrium and that IL-6 enhances HIV-1 transcription at this site. Thus, the ectocervix is an important site to be considered in heterosexual transmission of HIV-1.
