Islet of Langerhans

Compact endocrine clusters (~1 million per pancreas) containing β-cells (insulin), α-cells (glucagon), δ-cells (somatostatin), PP cells, and ε-cells (ghrelin). KATP channel-coupled glucose sensing drives pulsatile insulin secretion controlling systemic glycaemia.

Also known as: pancreatic islet, islet, islets of Langerhans, endocrine pancreas, pancreatic islet microorgan
