Interferon synthesis by human colostral leucocytes.

J W Lawton, K F Shortridge, R L Wong

    Archives of Disease in Childhood
    |February 1, 1979
    PubMed
    Summary

    Human colostral leukocytes show antiviral potential by producing interferon. However, prepartum cells yield more interferon than postpartum cells, and colostral cells are less effective than blood leukocytes.

    Area of Science:

    • Immunology
    • Virology
    • Cell Biology

    Background:

    • Human colostrum contains leukocytes with potential immune functions.
    • Interferon production is a key antiviral defense mechanism.

    Purpose of the Study:

    • To assess the antiviral potential of human colostral leukocytes.
    • To evaluate interferon production by colostral leukocytes in response to stimuli.

    Main Methods:

    • Leukocytes were isolated from human colostrum.
    • Cells were cultured and stimulated with mitogens or Newcastle disease virus (NDV).
    • Interferon production was measured and characterized.

    Main Results:

    • Colostral leukocytes produced interferon with characteristics similar to normal human leukocyte interferon.
    • Interferon levels were higher in prepartum colostral cells compared to postpartum cells.
    • Colostral leukocytes demonstrated lower interferon production efficiency than blood leukocytes.

    Conclusions:

    • Human colostral leukocytes possess antiviral capabilities through interferon production.
    • The functional capacity of these cells varies with the stage of parturition.
    • Colostral leukocytes may play a role in neonatal immunity, though less efficiently than circulating leukocytes.
