Impact of seminal cytomegalovirus replication on HIV-1 dynamics between blood and semen.

ABSTRACT: The genital tract of individuals infected with human immunodeficiency virus type 1 (HIV-1) is an anatomic compartment that supports local HIV-1 and cytomegalovirus (CMV) replication. This study investigated the association of seminal CMV replication with changes in HIV-1 clonal expansion, evolution and phylogenetic compartmentalization between blood and semen. Fourteen paired blood and semen samples were analyzed from four untreated subjects. Clonal sequences (n = 607) were generated from extracted HIV-1 RNA (env C2-V3 region), and HIV-1 and CMV levels were measured in the seminal plasma by real-time PCR. Sequence alignments were evaluated for: (i) viral compartmentalization between semen and blood samples using Slatkin-Maddison and F(ST) methods, (ii) different nucleotide substitution rat
