Gut hormones in disease.

S R Bloom, J M Polak

    Scandinavian Journal of Gastroenterology. Supplement
    |January 1, 1983

    Summary
    This summary is machine-generated.

    Gastrointestinal neuroendocrinology relies on mucosal endocrine cells and enteric nerves. New technologies like neuron-specific enolase (NSE) and immunocytochemistry help visualize and understand these systems and their role in disease.

    Area of Science:

    • Gastrointestinal neuroendocrinology
    • Cellular and molecular endocrinology
    • Neuroscience

    Background:

    • The gastrointestinal tract's neuroendocrine system comprises mucosal endocrine cells and intrinsic enteric nerves.
    • These cells produce peptides stored in characteristic secretory granules, acting locally, systemically, or as neurotransmitters.
    • Understanding their complex interplay requires novel physiological and technological approaches.

    Purpose of the Study:

    • To review advancements in investigating the diffuse neuroendocrine system of the gut.
    • To highlight how new technologies enable visualization and characterization of neuroendocrine cells and peptide biosynthesis.
    • To discuss the potential of these advancements in understanding neuroendocrine roles in disease.

    Main Methods:

    • Utilizing neuron-specific enolase (NSE) as a marker for visualizing the entire diffuse neuroendocrine system.
    • Employing advanced chemical characterization of peptides to generate specific antibodies.
    • Applying immunocytochemical methods, including gold particulate markers, to visualize intracellular peptide biosynthesis.

    Main Results:

    • Technological developments have significantly improved the investigation of the gut's diffuse neuroendocrine system.
    • Neuron-specific enolase (NSE) allows for comprehensive visualization of this system.
    • New immunocytochemical techniques enable detailed study of peptide biosynthesis and intracellular events.

    Conclusions:

    • Ongoing discovery of regulatory peptides and application of advanced immunological probes like monoclonal antibodies will further elucidate the diffuse neuroendocrine system.
    • These advancements promise to reveal the full extent of the system and its abnormalities in disease.
    • This research opens new avenues for clinical endocrinology and understanding gut function.
