IL1B and Cognitive impairment: Our results showed that EE: (1) decreased the pro-inflammatory cytokines IL-1β and TNF-α and enhanced levels of the anti-inflammatory cytokine IL-10 after mTBI; (2) mitigated mTBI-induced cognitive impairment; and (3) attenuated mTBI-induced downregulation in pAMPK/AMPK ratio and uMtCK levels.
