Fig. 6. High glucose triggered necroptosis in BV2 microglia.

Fig. 6

The BV2 murine microglial cell lines were treated with high glucose (50 mM) for 48 h. For treatments, cells were pre-stimulated with GSK-872 (5 μM) before high glucose stimulation for 12 h. D-Mannitol was used as an osmotic control. A The protein levels of RIP1 and RIP3 were detected by western blotting. B The protein levels of MLKL and p-MLKL were detected by western blotting. C, D Combined p-MLKL immunostaining and TUNEL assays on BV2 microglial cells under high glucose and normal condition. Ten images in each group were randomly chosen for analysis. E, F The levels of TNF-α and MCP-1 in cultured microglia was detected using TNF-α and MCP-1 ELISA kit respectively. HG high glucose. GSK, the specific RIP3 inhibitor GSK-872. Western blotting and ELISA assays were repeated 3 times. Data were mean ± S.D. *P < 0.05, **P < 0.01, ***P < 0.001, ns no significance.
