Autophagy is a genetically programmed dynamic process for the lysosomal degradation and recycling of bulk cytoplasmic contents, abnormal proteins, and damaged organelles.
Autophagy is a highly regulated process that is responsible for degrading long-lived or aggregated proteins and damaged organelles and is characterized by sequestration of cytoplasmic cargoes into double-membrane vesicles called autophagosomes.
