Synaptic plasticity, with its two most studied forms, long-term potentiation (LTP) and long-term depression (LTD), is the cellular mechanism underlying learning and memory. Although it has been known for two decades that bidirectional synaptic plasticity necessitates a corresponding bidirectional regulation

Autophagy maintains metabolism in response to starvation, but each nutrient is sensed distinctly. Amino acid deficiency suppresses mechanistic target of rapamycin complex 1 (MTORC1), while glucose deficiency promotes AMP-activated protein kinase (AMPK). The MTORC1 and AMPK signaling pathways converge onto

Autophagy is a highly- evolutionarily-conserved catabolic pathway activated by various cellular stresses. Recently, non-canonical autophagy (NCA), which does not require all of the ATG proteins to form autophagosome or autophagosome-like structures, has been found in various conditions. Moreover, mounting evidence
