Obesity triggers stress in the endoplasmic reticulum (ER), a network of intracellular membranes involved in protein folding and trafficking. That ER stress in turn disrupts insulin signaling. Özcan et al. investigated whether a class of small-molecule drugs that normalize ER function, called "chemical chaperones," might have therapeutic benefits in type 2 diabetes. These drugs were found to correct hyperglycemia and restore insulin sensitivity in genetically obese and diabetic mice, suggesting that they merit further study as a potential therapy for human diabetes.
