The objective of this study was to functionally assess gamma/delta (␥␦) T cells following pathogenic human immunodeficiency virus (HIV) infection of humans and nonpathogenic simian immunodeficiency virus (SIV) infection of sooty mangabeys. ␥␦ T cells were obtained from peripheral blood samples from patients and sooty mangabeys that exhibited either a CD4-healthy (>200 CD4ⴙ T cells/␮l blood) or CD4-low (
