Metabolic specialisation of α-cells: In search of pathways causal to hyperglucagonemia
Grant amount: DKK 9,999,821

Jakob G. Knudsen says: “Type 2 diabetes (T2D) affects more than 400 million people worldwide. Despite great efforts, we have so far been unable to curb the increasing prevalence. While insulin resistance and lack of insulin secretion seems to be the major cause of T2D, it has become clear that the hormone glucagon also plays a critical role. Glucagon is normally secreted to increase plasma glucose levels during fasting but in T2D, glucagon suddenly appears at higher plasma glucose levels and causes hyperglycemia. In this project, Jakob Knudsen will advance single cell resolution microscopy and genetically modify models to determine how α-cell metabolism and glucagon secretion changes in response to metabolic challenges. this way we can explore the mechanisms underlying glucagon secretion in T2D. The understanding of α­-cell metabolism and the basic mechanism of glucagon secretion will not only benefit diabetes research, but also lead to new possible treatments for T2D.”
