  • Research summary

    Type 2 diabetes mellitus (T2DM) currently affects ~ 10% of the adult population and represents a significant burden on UK finances. This life-threatening disease state is typified by a failure of the beta cell mass to adapt their output in response to increased peripheral insulin resistance. The resulting metabolic dysregulation prevents sufferers from leading a normal healthy life due to a range of sequelae including cardiovascular and kidney disease, retinal degeneration, amputation and cancer. Despite this, the mechanisms underlying insulin secretion and beta cell failure remain poorly characterized. In the present proposal, next-generation optical tools, recombinant engineering and cell-resolution imaging approaches will be deployed to understand how insulin release is regulated within rodent and human islets of Langerhans from both rodents and humans. In particular, we will seek to understand how subtle differences in the genetic and protein barcode of cells may predispose to T2DM. Together, these in vitro studies promise to gain unique insight into the complex molecular and cellular drivers of insulin and glucagon release, before understanding how this may fail during T2DM. The project is particularly timely, since it aims to identify novel targets with which to reduce disease co-morbidities across lifespan, thus allowing healthy ageing of individuals with T2DM.
