Figure 6. Effects of Hyp on depressive-like behaviors of chronic stress-induced mice. (A) Compared with the control group, the CUMS group had a slower rate of body weight growth. Body weight growth was faster in the CUMS+paroxetine and CUMS+Hyp groups than in the CUMS group. (B) Hyp and paroxetine significantly increased the sucrose preference rate of CUMS mice in the sucrose preference test. (C) Compared with the control group, the CUMS group increased the immobility time of TST. TST immobility time was significantly reduced by CUMS+paroxetine and CUMS+Hyp. (D) The immobility time of the FST was increased in the CUMS group compared with the control group. CUMS+paroxetine and CUMS+Hyp significantly decreased the immobility time of FST. Results are shown as the mean from multiple experiments, n = 5, one-way ANOVA, followed by Dunnett multiple comparison test; * p < 0.05, ** p < 0.01, and *** p < 0.001.

Figure 7. Hyp reduced NLRP1 inflammasome activation and inflammatory response in the hippocampus of chronic-stress-induced mice. (A–C) Statistical results show that Hyp decreased the mRNA expression of (A) NLRP1, (B) ASC, and (C) caspase-1 in the hippocampus of chronic stress-induced mice. (D–G) Statistical results show that Hyp reduced the mRNA levels of (D) IL-6, (E) IL-18, (F) IL-1β, and (G) TNF-α in the hippocampus of chronic-stress-induced mice. Results are shown as the mean from multiple experiments, n = 5, one-way ANOVA, followed by Dunnett multiple comparison test; * p < 0.05, ** p < 0.01, and *** p < 0.001.
