Abstract
Because of the difficulty of obtaining Indian-origin rhesus macaques, Chinese-origin rhesus macaques (CR) and Vietnamese-origin cynomolgus macaques (CM) are now used frequently in HIV/AIDS research. Nonetheless, the effects of TRIM5α polymorphism on viral replication in both CR and CM are unclear. To address these questions, we recruited 70 unrelated CR and 40 unrelated CM and studied the effect of TRIM5α polymorphism on HIV-2ROD and SIVmac239 replication in PBMCs. We found that 3 polymorphisms, located in the B30.2 domain of CR TRIM5α formed a haplotype and affected HIV-2ROD replication. In addition, we found that the variant Y178H, located in the Coiled-coil domain of CM TRIM5α, affected TRIM5α-mediated HIV-2ROD restriction. Finally, two polymorphisms, located in the Coiled-coil domain, altered anti-SIVmac239 activity in CR. We concluded that, CM TRIM5α polymorphism could alter HIV-2ROD infection; however, a different domain of CR TRIM5α was responsible for restricting different virus replication.
