摘要：

Cordyceps polysaccharide (CSP) has been shown to exhibit anti-inflammatory and antioxidant effects, with potential applications in ischemic stroke. This work is to explore the interventional potential of CSP in MCAO rats and the effects on the intestinal and cerebral IL-23/IL-17 axis. We conducted pharmacological experiments and mechanism exploration in MCAO rats. Our research showed that CSP improved the neurological function and cerebral pathological morphology, reduced cerebral infarction volume and water content in MCAO rats. We also found that CSP significantly decreased the IL-1 beta, TNF-alpha and IL-6 in the ischemic brain and enhanced the ability of MCAO rats to resist oxidative stress. Additionally, CSP improved intestinal barrier, inhibited the activation of the TLR4/Myd88/NF-kappa beta signaling pathway and IL-23/IL-17 axis. The study results demonstrated the effectiveness of CSP in interfering with MCAO rats. The mechanism appears to be related to protecting the intestinal barrier and inhibiting the IL-23/IL-17 axis.
