From: Antibody-dependent CD56+ T cell responses are functionally impaired in long-term HIV-1 infection
Comparisons of HIV-1-specific CD56+ T-mediated ADCC activity in men who have sex with men (MSM) with HIV-1 infection between 1 and 3 years (n = 22) and >3 years (n = 13). a The representative flow plots indicated CD107a expression and IFNγ production by CD56+ T cells. HIV-1-specific ADCC responses were compared between MSM with HIV-1 infection for 1–3 years and >3 years. Whole blood samples were incubated at 37 °C for 5 h with HIV-1 gag, pol, and env peptide pools respectively. HIV-1-specific ADCC responses were identified by expression of CD107a (b) and IFNγ (c) in CD56+ T cells. The horizontal bar indicated median values. All P values were two-tailed and considered significant when lower than 0.05
