Robust rise of both IFN-\(\gamma\) (A) and IL-2 (B) secreting PBMCs was shown in both healthy control group and T2DM group after ex-vivo ELISpot assays. (C) Representative ELISpot wells of IFN-\(\gamma\) and IL-2 ELISpot assay with positive control (stimulated with PWM) and negative control (RPMI medium and cell suspension).
