In the T2D group, we found significant positive correlations between the levels of anti-AGE EL IgM antibodies and MMP-2 (r = 0.322; p = 0.013; Figure 2), as well as between the levels of anti-AGE EL IgG antibodies and CRP (r = 0.265; p = 0.042; Figure 3). Here, CD40LG is linked to type 2 diabetes mellitus.
