Anti-HERV-K (HML-2) capsid response in HIV infection. The detection of total IgG against HERV-K (HML-2) gag was performed for 40 seronegative low risk healthy donors (SNLR white dots), 40 elite controllers (EC grey dots) and 40 viremic non-controllers (VNC thin black dots) by peptide-based ELISA using sequences determined in Fig. 2. Each graph represents ELISA for one linear epitope and represented by their number on the top of each graph (a–h). Error bars represent SEM. The figure shows the representative results of at least three independent experiments. The statistical significance between the different groups was established using a Kruskal–Wallis and Dunn’s Multiple Comparison test and a p value <0.05 was considered as significant. *p < 0.05; **p < 0.01; ***p < 0.001
