Co-receptor usage of BOB/GPR15 in addition to CCR5 has no significant effect on replication of simian immunodeficiency virus in vivo.

Human immunodeficiency virus type 2 (HIV-2) and the closely related simian immunodeficiency viruses (SIVs) frequently use the orphan receptor BOB/GPR15 in addition to the chemokine receptor CCR5 for efficient entry and replication. However, the role of BOB/GPR15 in replication and pathogenesis of HIV-2 and SIV in vivo is unclear. This study shows that a single amino acid substitution in the V3 loop of the pathogenic SIVmac239 clone, 321P-->S, impaired the ability to use BOB/GPR15 for entry and replication but had little effect on the ability to use CCR5. This envelope variant replicated with an efficiency comparable with the parental SIVmac239 isolate in rhesus macaques. Furthermore, the mutant genotype and phenotype remained stable even after the onset of immunodeficiency. These results suggest that this cofactor plays only a minor role for the pathogenicity of the HIV-2/SIVmac/SIVsm group of primate lentiviruses.[1]
