Growing evidence suggests it takes a sustained viral infection in the right genetic environment to lead to type 1 diabetes.

The story of type 1 diabetes begins in the pancreas, long seen as a battleground between insulin-producing beta cells and misdirected immune defenders. Scientists have been searching for ways to spot this internal warfare early enough to prevent a lifelong disease that depletes the body’s source of insulin. Two new papers published Wednesday in Science Translational Medicine offer new clues to what happens in these beta cells before type 1 diabetes emerges. Experiments in human cells and in mouse models used biosensors and genetic analyses to illuminate this pathway and detect possible ways…
