Autophagic lysosome reformation (ARL). Schematic illustration of the principal steps involved in the autophagic lysosome reformation. Initially, the tubular structures emerge from autolysosomes (yellow) and small vesicles bud off these tubules (protolysosome, in light green) to mature into functional lysosomes (dark green). The renewed pool of lysosomes can re-enter the flux fusing with the autophagosomes (orange) and generating autolysosome.
