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 tre...

Hannah Robinson was the first adult in the UK to be given the new immunotherapy drug Teplizumab, which aims to slow down the development of type 1 diabetes. Hannah had multiple pancreatic autoantibodies and hence is on the path to developing Type 1 diabetes (Series 4 Episode 3). Her consultant, Nick Thomas, arranged 14 consecutive daily hospital visits for her to receive the drug through a drip. Send us a text

Send us a text We talk to John Dennis, a data science researcher working in the University of Exeter. He used data from 1 million people with Type 2 diabetes to discover how the clinical characteristics of a patient alter the glucose lowering with different treatments. John’s 5 drug model, published in the Lancet in late February 2025, uses simple clinical information to identify, for the first time, the best glucose lowering treatment for a patient. The model selected best treatment lo...
