A recent study reported that higher levels of pro‐inflammatory Vδ1+ T cells correlated with lower gut‐associated HIV viral load,93 and another study in rhesus macaques found that levels of CD8+ Vδ2+ T cells in the female reproductive tract correlated with lower SIV viral loads.94 Vδ1+ T cells expanding in HIV‐infected individuals may also protect from other infections. This evidence concerns the gene CD8A and infection.
