What’s Eating the Epidermis What’s Eating the Epidermis? In Vivo Autophagy Manipulation via Subcutaneous MicroRNA Delivery  Cory L. Simpson  Journal of Investigative Dermatology  Volume 138, Issue 7, Pages 1463-1465 (July 2018) DOI: 10.1016/j.jid.2018.04.002 Copyright © 2018 The Author Terms and Conditions

Figure 1 Autophagy allows cells to recycle cellular debris, protein aggregates, and injured organelles. To sequester cargo intended for degradation, cells begin by forming an isolation membrane. Immature LC3 resides in the cytoplasm, but upon up-regulation of autophagy, pro-LC3 is cleaved and then lipidated (activated) by Atg family members 3, 4, and 7. Mature LC3 is subsequently incorporated into the elongating isolation membrane via the activity of Atg 5, 12, and 16L to surround the cargo, forming a phagophore. Closure of the double membrane generates a mature autophagosome, which can subsequently fuse with lysosomes via the activity of SNARE protein complexes, thus forming an autolysosome capable of cargo degradation.
