Localized de novo phospholipid synthesis drives autophagosome biogenesis.

abstract：:Autophagosome formation is a complex cellular process, which requires major membrane rearrangements leading to the creation of a relatively large double-membrane vesicle that directs its contents to the lysosome for degradation. Although various membrane compartments have been identified as sources for autophagosomal ...
