In PBMCs, the expression of genes encoding TNF-α and IL-6 was elevated in individuals with type 2 diabetes with micro- (n = 29) and macroalbuminuria (n = 31) compared with the control group (n = 22) and individuals with type 2 diabetes and normoalbuminuria (n = 18) [13]. Here, IL6 is linked to type 2 diabetes mellitus.
