Interplay Between Lipid Metabolism and Autophagy

Frontiers in Cell and Developmental Biology, 2020
Autophagy is a self-eating process of using lysosomes to degrade macromolecular substances (e.g., proteins and organelles) that are damaged, degenerated, or aging. Lipid metabolism is the synthesis and degradation of lipids (e.g., triglycerides, steroids,
