Glucagon secretion in Type 1 diabetes

Project Details

Glucagon is an important glucose counter-regulatory hormone that is secreted by the α-cells of the pancreas. It is normally secreted during bouts of low blood sugar or hypoglycaemia. In Type 1 diabetes this response is lost soon after diagnosis, severely compromising the recovery from hypoglycaemia.

Hypoglycaemia is detected by glucose-sensing neurons that are located in several brain regions including the hypothalamus. Hypothalamic glucose-sensing neurons are important for control of adrenaline secretion during hypoglycaemia (Korim et al., 2016).

Using a combination of neurophysiological and neuroanatomical techniques, we are studying the mechanisms that underpin pancreatic glucagon secretion in diabetes.
