PERK signalling in neurodegenerative diseases: From ER stress to mitochondrial dysfunction and therapeutic opportunities
The PERK (PKR-like endoplasmic reticulum kinase) pathway is a key branch of the unfolded protein response (UPR), and is crucial for maintaining cellular homeostasis. In neurodegenerative diseases, factors such as misfolded protein accumulation and oxidative stress lead to sustained endoplasmic reticulum stress, thereby...
