Autophagy

Lysosome‑dependent catabolic mechanism by which cells sequester cytoplasmic material—organelles, protein aggregates, portions of cytosol—into double‑membrane autophagosomes that fuse with lysosomes for degradation and recycling of constituents.

A conserved intracellular catabolic process in which portions of cytoplasm, damaged organelles, or protein aggregates are sequestered into double‑membrane autophagosomes that fuse with lysosomes for degradation and recycling, supporting cellular homeostasis and adaptation to stress.
