ApoE-Dependent Lipid Handling by Median Eminence Microglia Preserves Myelin Integrity and Metabolic Function
This study reveals that median eminence microglia rely on ApoE-dependent lipid handling to maintain myelin integrity and metabolic function, a process disrupted by Western diet and the APOE4 isoform but therapeutically restored by activating liver X receptor signaling to improve leptin responsiveness and limit weight gain.
