Exercise promotes host anti-infection activity through CNDP2 metabolite-mediated inflammasome hyperactivation.

Exercise induces a hyperactivation-like state of the NLRP3 inflammasome, enhancing infection resistance by increasing cytokine secretion and reducing immune cell pyroptosis.

• Why it matters: Understanding how exercise boosts infection resistance at the molecular level can inform strategies to improve immune responses and guide exercise protocols for health benefits.
• What they did: The study examined the molecular interactions involving CNDP2, GSDMD, and γ-Glu-Cys, demonstrating that exercise promotes these interactions and the production of γ-Glu-Cys, which modulates inflammasome activity.
• The result: Findings suggest that exercise-induced molecular changes enable a controlled inflammasome hyperactivation, potentially improving anti-infection defenses and guiding exercise intensity standards.
