Control of prolactin secretion by the hypothalamic catecholamines.

R M MacLeod, I Login

    Advances in Sex Hormone Research
    |January 1, 1976
    PubMed
    Summary

    Neuroendocrine control of prolactin secretion involves complex mechanisms. The hypothalamus inhibits prolactin, and cerebrospinal fluid plays a key role, with various drugs affecting its secretion.

    Area of Science:

    • Neuroendocrinology
    • Hormone Regulation

    Background:

    • Prolactin secretion is regulated by complex neuroendocrine pathways.
    • The inhibitory influence of the hypothalamus on prolactin is not fully understood.
    • Cerebrospinal fluid's role in neuroendocrine regulation of prolactin is gaining importance.

    Purpose of the Study:

    • To explore the complex neuroendocrine control of prolactin secretion.
    • To investigate the role of cerebrospinal fluid in prolactin regulation.
    • To identify pharmacological agents that modulate prolactin secretion.

    Main Methods:

    • Review of existing literature on neuroendocrine control of prolactin.
    • Analysis of the effects of various pharmacological agents on prolactin secretion.

    Main Results:

    • The hypothalamus exerts a significant inhibitory effect on prolactin secretion.
    • Cerebrospinal fluid is increasingly recognized for its role in prolactin regulation.
    • Apomorphine and ergot alkaloids effectively inhibit prolactin secretion.
    • DMPEA, alpha-methyldopa, reserpine, and phenothiazines stimulate prolactin secretion.

    Conclusions:

    • Neuroendocrine control of prolactin is intricate, involving hypothalamic inhibition and cerebrospinal fluid.
    • Pharmacological agents offer distinct methods for either inhibiting or stimulating prolactin secretion.
