- Abstract
The restricted diversity of the major histocompatibility complex (MHC) of Mauritian cynomolgus macaques provides powerful opportunities for insight into host-viral interactions and cellular immune responses that restrict lentiviral infections. However, little is known about the effects of Mhc haplotypes on control of SIV in this species. Using microsatellite-based genotyping and allele-specific PCR, Mhc haplotypes were deduced for 35 macaques infected with the same stock of SIVmac251. Class I haplotype H6 was associated with a reduction in chronic phase viraemia ( p = 0.0145) while a similar association was observed for H6 class II ( p = 0.0063). An increase in chronic phase viraemia, albeit an insignificant trend, was observed in haplotype H5-positive animals. These results further emphasise the value of genetically defined populations of non-human primates in AIDS research and provide a foundation for detailed characterisation of MHC restricted cellular immune responses and the effects of host genetics on SIV replication in cynomolgus macaques.
