Type 1 diabetes usually develops as a result of autoimmune pancreatic beta-cell destruction in genetically susceptible individuals. Up to 90% of patients will have autoantibodies to at least one of 3 antigens: glutamic acid decarboxylase (GAD); insulin; and a tyrosine-phosphatase-like molecule, islet auto-antigen-2 (IA-2).  Beta-cell destruction proceeds sub-clinically for months to years as insulitis(inflammation of the beta cell). When 80% to 90% of beta cells have been destroyed, hyperglycaemia develops.The annual incidence of Type 1 diabetes.

The European Commission Directorate General for Research and Innovation (DG RTD) and the JDRF (formerly Juvenile Diabetes Research Foundation) jointly organized a workshop held in Brussels on type 1 diabetes with the ultimate goal of defining the state-of-art in the field, identifying gaps, and brainstorming about the possibilities offered by personalized medicine approaches in this area. Renowned investigators and regulators presented the latest advances and challenges concerning type 1 diabetes.
