The study aims to explore how HIF-1α/BNIP3-mediated mitophagy protects neuronal cells from cerebral ischemia/reperfusion injury (CIRI).
Analyzed the activation of the HIF-1α/BNIP3 pathway in neuronal cells
Evaluated mitophagy levels using specific biomarkers
Assessed NLRP3 inflammasome activity in response to CIRI
HIF-1α/BNIP3 pathway activation enhanced protective mitophagy in neuronal cells
Suppression of NLRP3 inflammasome activity was observed following mitophagy induction
Mitophagy was linked to reduced injury markers in CIRI conditions

Abstract

Activation of the HIF-1α/BNIP3 pathway drives protective mitophagy to suppress the NLRP3 inflammasome in neuronal cells, thereby conferring neuroprotection against CIRI. This study provides mechanistic insights into the protective role of HIF-1α/BNIP3-mediated mitophagy against CIRI, highlighting its potential as a therapeutic target for ischemic injury.
