DAG transport by ATG2A brings in DGAT2 to help lipid droplets grow

Longevity & Aging Weekly Brief ↗PubMed ↗DOI ↗OA ↗

Updated

Abstract

Essence

ATG2A may help grow by moving to droplets and thereby recruiting DGAT2 for synthesis at the droplet surface.

Evidence

This mechanistic lipid-biology study combined ATG2A-deficiency, DGAT2-relocation, DGAT2-inhibition, and in vitro DAG-recruitment experiments to test lipid droplet expansion.

Caveat

The findings define a cellular mechanism for lipid droplet growth but do not establish tissue-level or disease-level consequences.
