It has recently been shown that polymorphism at the rhesus macaque TRIM5 locus can affect simian immunodeficiency virus (SIV) replication. Here we show that TRIM5 alleles can also affect acquisition of SIVsmE660. Animals coexpressing the TRIM5 TFP and TRIM5 CypA alleles took significantly longer to become infected with SIVsmE660, but not SIVmac239, after repeated limiting-dose intrarectal challenge than did animals expressing other TRIM5 allele combinations. Our results indicate that the TRIM5 alleles can be a barrier to productive infection and that this should be taken into account when designing acquisition studies using SIVsmE660 or related viruses.
