Description

The abstract shows GRAMD1B overexpression increases cholesterol and impairs autophagy, but the mechanistic connection between cholesterol transport and autophagy dysfunction is not explained. Understanding this link is critical for targeting lipid-autophagy crosstalk in neurodegeneration.

Gap type: unexplained_observation Source paper: GRAMD1B is a regulator of lipid homeostasis, autophagic flux and phosphorylated tau. (2025, Nature communications, PMID:40204713)
