Beta-lipotropin and endorphins: implications of current knowledge.

R Guillemin

    Hospital Practice
    |November 1, 1978
    PubMed
    Summary

    Endorphins, derived from beta-lipotropin, influence mood and behavior. Their synthesis in both the brain and GI tract highlights crucial CNS-endocrine-environmental connections.

    Area of Science:

    • Neuroendocrinology
    • Gastroenterology
    • Behavioral Neuroscience

    Background:

    • Endorphins are metabolites of the pituitary hormone beta-lipotropin.
    • Endorphins are secreted with ACTH (adrenocorticotropic hormone) during stress responses.
    • Evidence suggests endorphins function as neurotransmitters within the gastrointestinal (GI) tract.

    Purpose of the Study:

    • To explore the role of endorphins in central nervous system (CNS) homeostasis.
    • To investigate the implications of endorphin synthesis in both the brain and GI tract.
    • To shed light on the interrelationships between the CNS, endocrine system, and environmental factors.

    Main Methods:

    • Review of existing evidence on endorphin function.
    • Analysis of endorphin secretion patterns during stress.
    • Examination of the sites of endorphin synthesis.

    Main Results:

    • Endorphins significantly impact mood and behavior.
    • Endorphins are co-secreted with ACTH in response to stress.
    • Endorphins are synthesized in both the brain and the GI tract.

    Conclusions:

    • Endorphins play a vital role in maintaining CNS homeostasis.
    • The dual synthesis sites of endorphins reveal novel CNS-endocrine-environmental interactions.
