Now we report that HIV-1-mediated downmodulation of HLA-C was associated with reduced binding to its respective inhibitory receptors. Despite this, HLA-C-licensed NK cells displayed reduced antiviral activity compared to their unlicensed counterparts, potentially due to residual binding to the respective inhibitory receptors. Nevertheless, NK cells were able to sense alterations of HLA-C expression demonstrated by increased antiviral activity when exposed to viral strains with differential abilities to downmodulate HLA-C. These results suggest that the capability of HLA-C-licensed NK cells to control HIV-1 replication is determined by the strength of KIR/HLA-C interactions and is thus dependent on both host genetics and the extent of virus-mediated HLA-C downregulation.",
