Abstract |
Three men from a proven homosexual human immunodeficiency virus type 1 (HIV-1) transmission cluster showed large variation in their clinical course of infection. To evaluate the effect of evolution of the same viral variant in these three patients, we analysed sequence variation in the capsid protein and determined the impact of the observed variation on viral replication fitness in vitro. Viral gag sequences from all three patients contained a mutation at position 242, T242N or T242S, which have been associated with lower virus replication in vitro. Interestingly, HIV-1 variants from patients with a progressive clinical course of infection developed compensatory mutations within the capsid that restored viral fitness, instead of reversion of the T242S mutation. In HIV-1 variants from patient 1, an HLA-B57(+) elite controller, no compensatory mutations emerged during follow-up. |
