Secretin, a hormone discovered 100 years ago, regulates pancreatic and gastric functions. Further research is needed to define its full physiological roles and develop specific antagonists.

Area of Science:

  • Gastroenterology and endocrinology research.
  • Focus on hormonal regulation of digestive functions.

Background:

  • Secretin, discovered in 1902, has been extensively studied over the past century.
  • Key milestones include isolation, structural determination, and receptor identification.

Purpose of the Study:

  • To review the historical research and current understanding of secretin.
  • To identify areas for future research in secretin's physiology and therapeutic potential.

Main Methods:

  • Review of historical scientific literature and research findings on secretin.
  • Analysis of established techniques like radioimmunoassay and gene cloning.

Main Results:

  • Secretin regulates pancreatic exocrine secretion, gastric acid, and motility.

  • Hormonal and neurohormonal interactions, particularly the vagus nerve, are crucial for secretin's actions.

    • Conclusions:

    • While secretin's role in digestion is clear, its function in the central nervous system and extragastrointestinal organs requires further investigation.
    • Development of secretin receptor antagonists and elucidation of neural regulatory mechanisms are future research priorities.
