Description

The study reveals distinct temporal dynamics of ESCRT recruitment during different autophagy types but doesn’t explain why mitophagy requires twice the ESCRT engagement time. Understanding this timing difference could reveal fundamental mechanistic distinctions between autophagy subtypes relevant to neurodegeneration.
