IL10 and type 2 diabetes mellitus: Interestingly, when these comparisons were applied only in the T2DM patient group (Table 4), IL-10 -819 T/C polymorphism showed a difference between cytokine levels and genotypes (p = 0.021): IL-10 levels in the TT genotype (256 (207) fg/mL] were significantly higher than in the CC genotype (182 (57) fg/mL] (p = 0.006).
