ATF4 activates a transcriptional program that chronically suppresses mTOR activity and promotes neurodegeneration in Parkinson disease models.
The integrated stress response (ISR) enables cells to adapt to diverse cellular stresses, but during chronic or unresolved stress it becomes maladaptive and is implicated in neurodegenerative diseases, including Parkinson disease (PD). The mechanisms underlying maladaptive ISR-driven neurodegeneration, however, remain...
