Figure 5. Inhibitor of GSK3β, SB216763, attenuates the phosphorylation of NF-κB, expression of NLRP3 and IL-1β, as well as the phosphorylation of tau. (A, B) Phosphorylation levels of NF-κB and the expression levels of NLRP3 and IL-1β as well as the phosphorylation of tau were determined in western blots of samples from MAPT Tg mice treated with KA (10 mg/kg) and/or SB216763 (1 mg/kg) together with KA (10 mg/kg). The KA group was given i.p. injection of 10 mg/kg KA. The SB216763+KA group mice were additionally given i.p. injections of 1 mg/kg SB216763. Both groups were assessed after 48 h. (C, D) Phosphorylation levels of NF-κB and the expression levels of NLRP3 and IL-1β as well as the phosphorylation of tau were determined by western blots in cells treated with KA (10 μM) and/or SB216763 (2 μM) together with KA (10 μM). The KA group was treated with 10 μM KA. The SB216763+KA group was additionally treated with 2 μM SB216763. Both groups were assessed after 48 h. The optical density of bands in western blots was analyzed by Image J software (*P < 0.05; **P < 0.01; ***P < 0.001 vs. the control group; #P < 0.05; ###P < 0.001 vs. the KA-only group).
