In a groundbreaking study, scientists have uncovered a new class of gut-derived molecules in infancy that could reshape how researchers understand the development of type 1 diabetes. The international research team, led by experts at the University of Turku and Örebro University, investigated stool samples from more than 300 children between the ages of 3 and 36 months, all of whom had a genetic predisposition for type 1 diabetes.
