Figure Lengend Snippet: Increased plasma levels of anti-CD4 IgG in HIV+ cocaine users and its effect on CD4+ T cell death through ADCC. This study included HIV-negative cocaine users (HIV–/D) and non-users (HIV–/ND), and aviremic ART-treated HIV+ cocaine users (HIV+/D) and non-users (HIV+/ND). The median plasma anti-CD4 IgG levels (A) and CD4+ T cell counts (B) and their correlations in HIV+ subjects (C) were evaluated. (D) The ADCC was performed in CD4+ T and NK cells in the presence of 5 µg/mL of purified anti-CD4 IgGs from ART-treated HIV+ cocaine users (HIV+/D), anti-CD4 IgGs from ART-naive HIV+ cocaine users (Neg1), total IgGs (Neg2) from ART-treated HIV+ cocaine users and an anti-CD4 mAb (Pos). The percent of CD4+ T cytolysis was assessed using flow cytometry. Non-parametric Mann–Whitney U and Spearman correlation tests. *p<0.05; **p<0.01.
