Association of IL-2 production and CD4+ T cell proliferation in response to M. tuberculosis antigens. a The gating strategy for CFSE lost proliferating CD4+ T cells in the Media (unstimulated control), ESAT-6, PPD and PHA (positive control) stimulated cells. Numbers indicate the percentage CFST lost cells among the CD4+ T cells. b Correlation between frequency of IL-2-secreting cells and proliferating CD4+ T cells among total PBMCs after stimulation with PPD (n = 9) and ESAT-6 (n = 10). Spearman correlation was used to calculate correlation coefficients (rs) and p values
