Abstract
A number of age‐dependent degenerative diseases are caused by chronic endoplasmic reticulum (ER) stress in vital cells. In many cases, the afflicted cells suffer from ER stress since birth, but the death of irreplaceable cells occurs only late in life. Although our understanding of ER stress‐induced cell death has advanced significantly, most of the known mechanisms involve pathways that signal within hours, and it remains unclear how these pathways regulate cell death that occurs only decades later. Here, I highlight the conceptual issues and suggest ways to make sense of the age‐related effect of ER stress‐induced cell death in degenerative diseases.
