[Editorial] Towards a better understanding of type 1 diabetes
According to the NCD Risk Factor Collaboration, an estimated 422 million people worldwide were living with diabetes in 2014—four fold more than 35 years ago. Type 2 diabetes represents the majority of the epidemic (85–95%), and as a consequence type 1 diabetes has too often been overlooked. Today’s Lancet features a clinical Series on type 1 diabetes—an autoimmune disease in which insulin-producing β cells of the pancreas are destroyed. The precise aetiology and pathogenesis of type 1 diabetes remain a subject for research.
