Figure 4. Sal inhibited pyroptosis via the TLR4/MyD88/NF-κB signaling pathways in PD mice. (A) Sal inhibited TLR4, MyD88, p-IкBα and p-NF-κB in SN and striatum of PD mice by western blotting (n = 3). (B) Sal inhibited TLR4 in SN and striatum by immunohistochemical staining. Original magnification: x200. All data are represented as mean ± SD. # P < 0.05, ## P < 0.01 vs. control group, *P < 0.05, **P < 0.01 vs MPTP group.
