Abstract

expression was upregulated in the ischemic penumbra of mouse models and postmortem brain tissues from stroke patients.

  • Increased NLRC5 levels were found in activated microglia after ischemic stroke.
  • Deletion of NLRC5 in microglia resulted in significantly improved neurological outcomes and reduced brain damage in mice.
  • NLRC5 induction by various stimuli led to increased release of pro-inflammatory cytokines and neurotoxicity from microglia.
  • NLRC5 disrupted lysosomal function, which is crucial for the degradation of proteins and cellular debris.
  • The interaction between NLRC5 and ISG15 prevented ISG15 from being degraded by , contributing to inflammation.
