Studies in cell lines have demonstrated that CCR5 coreceptor levels influence the replication efficiency and Enfuvirtide (T-20) susceptibility of R5 HIV-1 strains. At present, however, the role that CCR5 levels on primary CD4 T cells--which are markedly lower than in cell lines and vary only approximately fivefold among most donors--may play in virus replication levels or susceptibility to T-20 is not known. In the present study we evaluated the impact of differences in CCR5 levels among donor CD4 T cells on the infection efficiency and T-20 susceptibility of R5 HIV-1.
