Gene discovery in neonatal diabetes to uncover the mechanisms regulating human pancreas development

De Franco Elisa , Wakeling Matthew , Owens Nick , Johnson Matthew , Flanagan Sarah , Hattersley Andrew T

Understanding how pancreatic beta-cells develop during human development is essential to advance current protocols aimed at developing insulin-producing beta-cells in vitro and highlight therapeutic targets for diabetes treatment. Identifying the single-gene mutations which result in individuals developing diabetes in the first 6 months of life (a condition called neonatal diabetes) has the potential to give unique insights into the genes regulating human beta-cells w...

Objectives: The crystal structures of the TSH receptor (TSHR) leucine rich repeat domain (LRD) bound to TSHR stimulating monoclonal autoantibody M22TM or to TSHR blocking monoclonal autoantibody K1-70TM and antibody free have been solved previously. Cryo-electron microscopy (cryo-EM) was now used to solve the structure of full length TSHR in complex with K1-70TM.Methods: Recombinant human TSHR expressed in CHO cells was i...

Introduction: Insulinomatosis is a rare disorder characterised by persistent hyperinsulinaemic hypoglycaemia (PHH) due to the occurrence of multifocal pancreatic insulinomas. This condition, whose pathogenesis is unknown, can occur in a familial setting. Paradoxically, while some family members develop PHH, others develop diabetes mellitus.Methods: We have identified a family with autosomal dominant familial insulinomatosis and diabetes. Exome sequencing...
