Figure 4. Effect of TRPV1 on NLRP3 inflammasome activation. (A–D) The relative protein expression of NLRP3, ASC, and caspase-1 p20 at 24 h post-SAH was assessed via western blot. (E) The protein level of IL-1β at 24 h post-SAH was assessed via ELISA. *p < 0.05, **p < 0.01, ***p < 0.001 and ****p < 0.0001.
