Figure 3. NBP inhibits NLRP3 inflammasome activation in the right striatum of the rat brain following pMCAO. (A) Representative NLRP3, Caspase-1 and IL-1β immunohistochemistry results are shown for the right striatum on the lesioned side at 200× magnification. Scale bar = 3 mm for the full coronal section; 100 μm for microscopic observation. (B) The score was calculated based on the percentage contribution of positive expression using IHC_Profiler in Image J. The data are presented as the mean ± SD, and were assessed using one-way ANOVA. # P < 0.05 vs. the sham group, ## P < 0.01 vs. the sham group, ### P < 0.001 vs. the sham group, * P < 0.05 vs. the pMCAO group, ** P < 0.01 vs. the pMCAO group, *** P < 0.001 vs. the pMCAO group, n = 3. Molecular docking of NBP to (C) NLRP3, (D) IL-1β, (E) Caspase-1.
