Study provides novel insights on dynamics of blood sugar levels and autoimmunity in early childhood: When and why does type 1 diabetes manifest in children? For the first time, researchers conducted a long-term study on infants and young children with increased genetic risk of type 1 diabetes. The results have now been published in the Journal of Clinical Investigation. The authors provide a unique picture of the dynamics of blood sugar regulation during early childhood and its relationship to the development of autoimmunity.
