Additional file 1: Fig. S1. L-Lactate did not induce apoptosis of CD4+ T cells. Representative flow cytometry plots using Annexin V/PI staining for apoptosis (A). CD4+ T cells were treated for 3 days with different L-Lactate concentrations (10 mM, 20 mM and 50 mM) and then stained with Annexin V/PI for flow cytometric analysis. Percentage of live CD4+ T cells after L-lactate incubation (B). Percentage of apoptotic cells after treatment with different L-Lactate concentrations (C). After 3 days of culture with L-Lactate, Treg induction from Th1 (D) and Th17 (E) cells was analyzed by FACS. Results represent the mean ± SD of two independent experiments and four biological samples for CD4+ T cells; *p < 0.05 (unpaired Kruskal–Wallis test). Unless otherwise indicated, comparisons were with control conditions, or with Th1 or Th17 cells.
