Endoplasmic reticulum (ER) stress is induced following the accumulation of unfolded proteins in the ER. This triggers the unfolded protein response, which initially acts to compensate for damage, but if prolonged or excessive can trigger cell death. Here, Reed and colleagues discuss the role of ER-initiated cell death pathways in diseases including neurodegeneration, hypoxia, heart disease, diabetes and immune disorders, while identifying promising therapeutic targets.
