The chemokine receptor CCR5 is known to be a critical determinant of human immunodeficiency virus (HIV) transmission and pathogenesis in the human host. Towards the development of a macaque model to evaluate the efficacy of vaccines and therapeutics against infection with CCR5-specific viruses, and to delineate the pathogenic properties of such viruses, we constructed a chimeric simian human immunodeficiency virus, SHIV(SF162), containing the env, tat, rev, and vpu genes from HIV-1(SF162) (R5, MT/NSI) in the context of the molecular clone simian immunodeficiency virus, SIV(mac239). Virus generated from this molecular clone was used to intravenously infect two juvenile macaques, followed by three consecutive serial blood/bone marrow transfusions. Animals infected with parental SHIV(SF162) (P1) had detectable levels of viral replication (as determined by p27(gag) production) within days of infection; however, viral set-points fell below detection by Week 3. Late passage animals (P3 and P4) had a two-log increase in the level of plasma p27(gag) antigen. These results demonstrate that in vivo serial passage of the R5-specific SHIV(SF162) enhanced its replicative capacity.
