The unfolded protein response (UPR) aims to relieve endoplasmic reticulum (ER) stress and restore protein homeostasis, but also contributes to disease. Here, Marciniak et al. assess small molecules that target ER stress and the UPR, highlighting those diseases in which the role of the UPR and its therapeutic modulation have been most well studied.
