Living organisms are often exposed to stress stimuli generated either by external or internal factors, and they need to respond accordingly. At a cellular level, stress usually triggers the activation of survival pathways that contribute to the recovery of cell homeostasis. However, when stress is too high, a process of cell death is initiated that eliminates the damaged cell.
