Beta Cell Stress Could Trigger Type 1 Diabetes @JDRF


Before T1d Stresses patients, stress on the beta cells may trigger T1D. Which matters because understanding how it works help find cures. So knowing what you don't know helps.

Study provides important clue in type 1 diabetes; could help scientists identify and validate potential drug targets to alleviate ER stress and preserve beta cell mass in T1D
In type 1 diabetes (T1D), pancreatic beta cells die from a misguided autoimmune attack, but how and why that happens is still unclear. Now, JDRF-funded scientists from the Indiana University School of Medicine have found that a specific type of cellular stress takes place in pancreatic beta cells before the onset of T1D, and that this stress response in the beta cell may in fact help ignite the autoimmune attack. These findings shed an entirely new light into the mystery behind how changes in the beta cell may play a role in the earliest stages of T1D, and adds a new perspective to our understanding how T1D progresses, and how to prevent and treat the disease. 
More about the study, published in the March 22 issue of the journal Diabetes, the researchers, led by Sarah Tersey, Ph.D., assistant research professor of pediatrics, and Raghavendra Mirmira, M.D., Ph.D., professor of pediatrics and medicine at the Indiana University School of Medicine is online here:
