WebHow do alpha cells detect glucose levels? The -cell of the pancreatic islet modulates glucose homeostasis by secreting glucagon that acts primarily by driving hepatic glucose production. Glucose sensing of the -cell becomes defective in both type 1 and type 2 diabetes, resulting in hyperglucagonemia that likely contributes to hyperglycemia (1). ... WebIf you haven’t eaten for a while, your blood glucose levels fall, triggering the release of glucagon from another group of pancreatic cells, the α cells. Glucagon acts on the liver, causing glycogen to be broken down into glucose and released into the bloodstream, causing blood sugar levels to go back up.

More specifically, it is detected by areas within the pancreas called islets of Langerhans. In this region there are 2 types of cells. Beta-cells and alpha-cells. Beta-cells will detect high blood glucose (e.g. after a meal) and secrete insulin.
