ATF4 activates a transcriptional program that chronically suppresses mTOR activity and promotes neurodegeneration in Parkinson disease models.
This work finds a critical pathway by which chronic ISR activation promotes neurodegeneration in neurotoxin and α synucleinopathy models of PD in vitro and in vivo and defines a maladaptive ISR/ATF4-mTOR pathway with potential therapeutic relevance for neurodegenerative disorders characterized by chronic ISR activation...
