Cellular stress signaling and the unfolded protein response in retinal degeneration: mechanisms and therapeutic implications

Abstract excerpt

BACKGROUND: The retina, as part of the central nervous system (CNS) with limited capacity for self-reparation and regeneration in mammals, is under cumulative environmental stress due to high-energy demands and rapid protein turnover. These stressors disrupt the cellular protein and metabolic homeostasis, which, if not alleviated, can lead to dysfunction and cell death of retinal neurons. One primary cellular...
