This review details how histamine, gastrin, and acetylcholine stimulate gastric acid secretion. Somatostatin acts as the primary inhibitor, regulating key cells involved in digestion.

Area of Science:

  • Gastroenterology
  • Neuroendocrinology
  • Physiology

Background:

  • Gastric acid secretion is a complex process regulated by multiple signaling molecules.
  • Understanding these regulatory mechanisms is crucial for treating acid-related disorders.

Purpose of the Study:

  • To summarize recent advances in understanding the regulation of gastric acid secretion.
  • To elucidate the roles of neurotransmitters, paracrine agents, and hormones in this process.

Main Methods:

  • Review of recently published data on gastric acid secretion.
  • Analysis of the interplay between various signaling molecules and gastric cells.

Main Results:

  • Histamine, gastrin, and acetylcholine are key stimulants of gastric acid secretion.

  • Somatostatin is the main inhibitor, acting on parietal, enterochromaffin-like (ECL), and gastrin cells.
  • H. pylori infection's complex effects on gastric acidity and reflux are highlighted.

    • Conclusions:

    • Recent findings enhance our understanding of gastric acid regulation.
    • The roles of histamine, gastrin, acetylcholine, and somatostatin in gastric physiology are further clarified.
    • Implications for conditions like rebound hyperacidity and H. pylori-associated changes are discussed.
