Research targeting the insulin-inhibitory receptor, called inceptor, unveils promising avenues for beta cell protection, offering hope for causal diabetes therapy. A novel study in mice with diet-induced obesity demonstrates that the knock-out of inceptor enhances glucose regulation, prompting its further exploration as a drug target for type 2 diabetes treatment. These findings, led by Helmholtz Munich in collaboration with the German Center for Diabetes Research, the Technical University of Munich, and the Ludwig-Maximilians-University Munich, drive advancements in diabetes research.
