ELN modulates CD4⁺ T cells phenotype in SHIV infected macaques.

Isolated cells from indicated tissues at necropsy were stained with LIVE/DEAD Aqua and an antibody combination of anti-: CD4, CD3, α₄β₇, CD69, CD95, CCR5 and LFA-1 (clone MEM148, which recognizes only the activated form). The frequency of cells expressing the indicated marker within live, singlets, CD3⁺ CD4⁺ T cells (within CD95⁺ for the α₄β₇^high) are shown. Bars represent mean ± SEM. p<0.05 is considered significant (Mann-Whitney).
