Abstract
Macroautophagy (hereafter called autophagy) is a catabolic, homeostatic process that is ubiquitous in eukaryotes and is conserved from yeast to human. The morphological hallmark of autophagy is the formation of cytosolic double-membrane vesicles that sequester cytoplasm and deliver it to the vacuole (the analog of the lysosome), where the cargos are degraded and the breakdown products are released through membrane permeases for reuse. Autophagy is connected to a wide range of pathophysiological conditions. Accordingly, it has attracted considerable attention in the last decade. A major, still unresolved, question concerns the origin of the membrane(s) that contribute to the formation of the autophagosome and the mechanism through which this compartment is generated.
