Frequency of invariant natural killer T (iNKT) cells in the blood and gastrointestinal-associated lymphoid tissue (GALT). (a) Representative gating strategy, iNKT cells were identified based on Vα24 and PBS57-CD1d tetramer-positive stainings. Frequency of iNKT cells in the (b) blood and in the (c) GALT for healthy controls (n=10), viremic (n=7), antiretroviral therapy (ART)-treated (n=13), and viremic controllers HIV-infected subjects (n=3). (d) Frequency of iNKT cells expressing CD4 in the blood and GALT of healthy controls (blood, n=8 and GALT, n=9) and HIV-infected subjects (blood, n=22 and GALT, n=17). *P<0.05 and **P<0.01. PBMC, peripheral blood mononuclear cell.
