Autophagy within the mushroom body protects from synapse aging in a non-cell autonomous manner
Abstract
The role of macroautophagy in neuronal processes mediating brain maintenance remains enigmatic. Authors show here that impairing autophagy within the major learning related brain center of Drosophila, and not other regions, triggered a form of presynaptic metaplasticity that was invariably connected to the absence of the specific component of aversive olfactory memory, which normally only declines in the course of aging process
