Childhood-onset type 1 diabetes (onset <age 18) and neurodevelopmental disorders, including attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, and intellectual disability, globally represent substantial health challenges. The conditions also pose substantial challenges to the individuals, their families, and healthcare systems.
News
Type 1 diabetes is an autoimmune disease, often with onset during childhood, that requires lifelong insulin therapy due to the loss of pancreatic beta-cells.
News
The deficiency of functional insulin-producing cells is a common feature of type 1 and late-stage type 2 diabetes. Previous studies have suggested that mammals have very limited capacity for regeneration of insulin-producing cells, but researchers at Karolinska Institutet have found how zebrafish can form new cells and thereby provide clues to possible future possibilities in diabetes. The study is published in the scientific journal Science Advances.

This year marks one hundred years since Frederick Banting and John MacLeod were awarded the Nobel prize for the discovery of insulin. The discovery has saved the lives of millions of people with diabetes worldwide, but the price is also one of the most debated. In their photo documentary, Professors Lars Rydén and Jan Lindsten talk about the history of the discovery, the problems associated with the award, and the importance the findings have had for today's treatment of diabetes.
