Integrative Multi-Omics Deciphers the Antiepileptic Mechanism of Dingxian Pill — Based on the Interaction Between the SIRT2/Raf/ERK Pathway and the Microbiota-Gut-Brain Axis
Description
This study deciphers the antiepileptic mechanism of the traditional compound Dingxian Pill (DXP), revealing a novel "gut-brain" dual-axis mode of action. We demonstrate that DXP alleviates temporal lobe epilepsy by simultaneously restoring gut microbiota homeostasis and directly inhibiting neuronal hyperexcitability. This study offers a promising therapeutic strategy for refractory epilepsy. Fig 1 DXP indeed undergoes metabolism in mice and reaches the hippocampus to exert its effects.
