Oxidative Stress Response
The oxidative stress response is a cellular defence system that neutralises reactive oxygen species (ROS) and restores redox balance. Through antioxidant enzymes, Nrf2‑mediated transcription, mitochondrial regulation and damage‑repair pathways, cells protect themselves from oxidative injury and maintain homeostasis.
Cellular Stress Response
Cellular stress responses are adaptive defence mechanisms that protect cells from environmental, metabolic and proteotoxic stress. By activating heat‑shock proteins, unfolded protein responses, antioxidant pathways and autophagy, cells restore homeostasis and maintain functional integrity under adverse conditions.
Protein Quality Control
Protein quality control (PQC) is a cellular surveillance system that preserves proteome integrity by monitoring protein folding, repairing misfolded proteins and eliminating damaged or aggregated species. Through coordinated action of chaperones, the ubiquitin–proteasome system and autophagy, PQC protects cells from proteotoxic stress and maintains homeostasis.
