What is the Meaning of Pancreatic Beta Cells?

Pancreatic Beta Cells are the highly specialized endocrine cells residing within the islets of Langerhans whose definitive function is the synthesis, storage, and regulated release of the peptide hormone insulin into the bloodstream. They are the body's primary glucose sensors. Their failure defines diabetes onset.

What is the Origin of Pancreatic Beta Cells?

The function of these cells was established through classic physiological experiments that pinpointed the source of blood glucose-lowering activity to the pancreatic islets.

What is the Mechanism of Pancreatic Beta Cells?

When plasma glucose levels rise, beta cells depolarize, leading to calcium influx which triggers the exocytosis of insulin-containing vesicles. This release mechanism is finely tuned by inputs from the autonomic nervous system and other metabolic hormones to maintain glucose homeostasis.
