Description
The study identifies a glucose-dependent PINK1/HK2 complex but doesn’t explain the mechanistic link between glucose sensing and mitophagy regulation. This gap is critical for understanding metabolic control of mitochondrial quality control.
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)
