In line with previous studies, our results showed a general trend of CCL5 elevation in T2DM subjects compared to the controls (irrespective of gender), but an increase in serum CCL5 in Group A T2DM subjects with normal body weight was highly pronounced with p < 0.001, in contrast to Groups B to D, as can be seen in Figure 4 and Figure 6 [22,36,41]. This evidence concerns the gene CCL5 and type 2 diabetes mellitus.
