Glial cells have emerged as equal partners to neurons in the development and maintenance of the nervous system. In this study, we examine the consequences of modulating glial ceramide metabolism on adult motor function. Glial reduction of ER-localised ceramide synthesis, as exemplified by knockdown (KD) of schlank or i...
Phagocytosis, a central process in innate immunity, depends on dynamic lipid remodelling, yet how cholesterol accumulates on late phagosomes remains unresolved. Here, we identify lysosomal acid lipase (LIPA) as a key cholesterol ester (CE) hydrolase driving cholesterol mobilization during phagosomal maturation. Using i...

Cholesteryl esters (CEs) are widely regarded as inert storage forms of cholesterol, yet their potential to directly engage cellular proteins remains largely unexplored. Here, we establish an integrated chemical proteomic platform to systematically define CE–protein interactions in mammalian cells. We developed and comp...
This study uncovers a novel, Dip2-mediated, unconventional Pkc1 signalling axis for maintaining mitochondrial homeostasis under nutrient transition and highlights how distinct lipid fingerprints enable precise control over organellar homeostasis.
