Cellular Stress Response

Meaning

The Cellular Stress Response is a fundamental, evolutionarily conserved network of biochemical pathways activated within a cell when it encounters conditions that threaten its homeostasis and survival. These stressors can be diverse, including thermal extremes, oxidative damage, nutrient deprivation, or exposure to toxins, all of which compromise normal cellular function. This protective mechanism is essential for cell survival and adaptation, playing a pivotal role in aging and disease pathology.
