Using a flow cytometry–based screening, we profiled 332 surface receptors on HIV-1–infected primary CD4<sup>+</sup> T cells and identified 23 down-regulated receptors, including known targets such as CD4, MHCI, CCR7, and CD62L. CD96, an inhibitory natural killer (NK) cell receptor poorly studied in human CD4<sup>+</sup> T cells, was markedly down-regulated. This modulation, mediated by the viral proteins Nef and Vpu, surpassed that of other NK-associated receptors such as CD155 and NTB-A and is conserved across lentiviruses. CD96<sup>Hi</sup> CD4<sup>+</sup> T cells exhibited a proinflammatory T<sub>H</sub>1/T<sub>H</sub>17 phenotype characterized by IFN-γ and IL-17 secretion and displayed impaired migration in vivo. Furthermore, CD96 ligation enhanced IFN-γ release upon viral peptide stimulation and promoted the secretion of T<sub>H</sub>1/T<sub>H</sub>17-associated cytokines.
