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,
