Editorial in Cell highligths paper from Rusten and co-workers.
The December 28 issue of "Cell" (impact factor 29.19) has an editorial about autophagy. Here, recent important publications that has contributed to our understanding of this process - by identifying new molecular players and new ways to manipulate autophagic pathways - are discussed. Among these is an article from Tor Erik Rusten and co-workers, entitled "ESCRTs and Fab1 regulate distinct steps of autophagy".

(from the ingress:) "The cellular process of autophagy (literally self-eating) is important during development and in the normal physiology of an organism. During autophagy, cellular components destined for degradation are enclosed in a double-membraned vesicle (the autophagosome), which then fuses with a lysosome where the contents are degraded and mostly recycled. Dysregulation of autophagy occurs in many diseases including cancer and neurodegeneration. Several recent papers contribute to our understanding of autophagy by identifying new molecular players in this process and new ways to manipulate autophagic pathways."
