Cytoprotection

Cytoprotection refers broadly to any cellular mechanism or intervention that protects cells from damage caused by chemical, physical, or biological stresses. It encompasses a range of endogenous processes such as autophagy, antioxidant response (e.g., Nrf2-ARE pathway), chaperone protein upregulation, and the action of protective factors like prostaglandins and heat-shock proteins. This cellular resilience can be induced by mild preconditioning stimuli, adaptive signaling, or exogenous agents, and is relevant to many fields including cancer biology, neuroscience, immunology, metabolic disease, and the gut-brain axis. Cytoprotection is not a specific molecular target but a functional consequence mediated by multiple pathways and factors depending on context.
