Cellular stress response is a general term covering a wide range of
molecular changes that
cells undergo in response to environmental
stressors, including extremes of temperature, exposure to toxins, and mechanical damage. The various processes involved in cellular stress responses serve the
adaptive purpose of protecting a cell against unfavorable environmental conditions, both through short term mechanisms that minimize acute damage to the cell's overall integrity, and through longer term mechanisms which provide the cell a measure of resiliency against similar adverse conditions.
