Series 4 episode 7. Sarah Richardson. Small extra-islet beta cells matter

Sarah Richardson talks about her new exciting research on insulin producing beta-cells that are single cells or small clusters rather than in islets.  These extra-islet beta-cells make up most of the insulin producing capacity of the pancreas in young children and are particularly susceptible to immune attack in Type 1 diabetes.  This important research explains why the loss of insulin producing cells in Type 1 diabetes is more severe in young children and informs future work on treating and preventing Type 1 diabetes.
