Cell biology: How to combat stress
Christopher V. Nicchitta1
Abstract
Life is full of stress, and all life forms — from bacteria to humans — have evolved ways of sensing and responding to it. The latest findings shed light on how cells deal with stress.
In cells, protein homeostasis — a delicate balance between maintaining protein conformations, refolding misfolded proteins and degrading damaged proteins — is normally maintained by regulatory networks that control protein synthesis and degradation. Moreover, molecular chaperones are key players in protein homeostasis, helping proteins to fold and preventing aggregation of misfolded proteins, which could have substantial, disease-related consequences1, 2.
