    Insights

    Human recombinant alpha 2-interferon (reaferon) enhances macrophage phagocytic activity. This immune-boosting effect is comparable to natural alpha-interferon, suggesting similar therapeutic potential.

    Area of Science:

    • Immunology
    • Biochemistry
    • Cell Biology

    Background:

    • Phagocytic activity of macrophages is crucial for immune response.
    • Interferons are key regulators of innate and adaptive immunity.
    • Recombinant interferons offer potential therapeutic applications.

    Purpose of the Study:

    • To investigate the effect of human recombinant alpha 2-interferon (reaferon) on macrophage phagocytic activity.
    • To compare the functional effects of recombinant and natural alpha-interferon on macrophages.

    Main Methods:

    • In vitro study using mouse peritoneal macrophages.
    • Assessment of phagocytic parameters: migration, spreading, adhesion, and antigen absorption.
    • Treatment with varying doses of reaferon.

    Main Results:

    • Reaferon significantly stimulated all studied parameters of macrophage phagocytic activity at doses of 5-5 X 10(2) I. U./ml.
    • The stimulating effect on macrophage functional activity was observed to be consistent between recombinant (alpha 2) interferon and natural alpha-interferon.

    Conclusions:

    • Human recombinant alpha 2-interferon (reaferon) possesses potent immune-stimulating properties.
    • Recombinant alpha 2-interferon demonstrates comparable efficacy to natural alpha-interferon in enhancing macrophage function.
    • These findings support the therapeutic potential of reaferon in modulating immune responses.
