True. Somatostatin, produced by delta cells (δ-cells) in the pancreatic islets of Langerhans, acts as a paracrine inhibitor within the pancreas. It suppresses the secretion of both insulin from beta cells and glucagon from alpha cells. This local regulatory action helps modulate the opposing actions of these two key glucose-regulating hormones, preventing extreme fluctuations in blood sugar. Somatostatin also inhibits the secretion of pancreatic exocrine enzymes and bicarbonate. Beyond the pancreas, somatostatin from the hypothalamus inhibits Growth Hormone (GH) and Thyroid-Stimulating Hormone (TSH) release from the pituitary, and in the gut, it inhibits gastrin, secretin, and other gastrointestinal hormones. Its broad inhibitory role makes it a physiological 'brake' on many endocrine and exocrine processes.
