Description

Xu, Rajan, Phoon, Ren, Hussain, and Schlame study how an enzyme recycles lysosome products in twenty twenty-six. Lysosomes break down phospholipids from cell membranes. That breakdown yields fragments that can be degraded or reused. One fragment type carries an unsaturated fatty acid chain.

The enzyme LPLAT7 sits in the endoplasmic reticulum and reacylates those fragments. It acts specifically on the lysosome derived, unsaturated forms. Knocking it out in liver cells blocked reuse of fragments from labelled phospholipids. In mice, knockout raised unsaturated fragment levels and cut key membrane lipids. Membrane regeneration slowed, and fat droplets accumulated instead. The authors say the enzyme shifts lipid flow from droplets toward membranes.
