Description
The abstract shows that neuroinflammation enhances mitophagy through PINK1/HK2 but doesn’t identify the intermediate signaling mechanisms. Understanding this pathway could reveal therapeutic targets for neuroinflammatory diseases.
Gap type: unexplained_observation Source paper: Hexokinase 2 interacts with PINK1 to facilitate mitophagy in astrocytes and restrain inflammation-induced neurotoxicity. (2025, Cell reports, PMID:40531619)
