Proposed mechanism underlining the synergistic beneficial effect of good glycemic control and clarithromycin treatment on neutrophils of T2D patients. Hyperglycemic environment induces the formation of LL-37-bearing NETs from T2D neutrophils, however they neither inhibit E. coli growth nor promote proliferation and differentiation of skin fibroblasts (SFs). The combination of glycemic control and clarithromycin increases externalization of LL-37 (red color) on T2D NETs, restoring the antibacterial activity of neutrophils and enhancing the healing capacity of SFs.
