Professor Patrik Rorsman talks about Diabetes and how beta cells within the pancreas control insulin secretion. Patrik Rorsman is professor of diabetic medicine in the Oxford Centre for Diabetes, Endocrinology and Metabolism. Professor Rorsman has been at the forefront of research on hormone-secreting cells in the pancreas for more than 20 years, work that is highly relevant to understanding the causes and treatment of type 2 diabetes. The Wellcome Trust award will allow him to study further the metabolic and hormonal regulation of hormone secretion in the pancreas.
