Prevalence and cross-clade reactivity of anti-Tat antibodies. CART-naïve, chronically HIV-infected individuals (n = 96) were tested for the presence of anti-Tat antibodies by ELISA. a Percentage of subjects with anti-clade C Tat IgG, IgA or IgM or anti-clade C Tat negative. b Number of anti-clade C Tat positive individuals able to recognize clade B Tat. c Number of subjects able to recognize clade B but not clade C Tat. d Heatmap showing, for single donors, positivity (black) or negativity (grey) toward clade C or clade B Tat for each isotype after unsupervised clustering. e Venn diagram analyses of the number of subjects recognizing clade B and/or C Tat stratified by the antibody isotype displayed
