Chronic hyperglycemia regulates microglia polarization through ERK5

Figure 4. Sustained ERK5 activation maintains HG-induced M2a polarization of microglia. (A) HG-culturing of MEK5DD-transfected and control microglia. (B) Western blot for pERK5, compared to the total ERK5 levels in HG- cultured, MEK5DD-transfected and control microglia at different time courses. (CI) RT-qPCR for iNOS (C), TNF-α (D), IL-6 (E), IL-12 (F), IL-10 (G), Arg-1 (H) and CD206 (I) mRNA levels in HG- cultured, MEK5DD-transfected and control microglia at different time points. (J) TUNEL assay on HCN-2 cells. N=5. *p<0.05
