Isoprinosine as an immunopotentiator

G Renoux, M Renoux, J M Guillaumin

    Journal of Immunopharmacology
    |January 1, 1979
    PubMed
    Summary

    Isoprinosine, an antiviral compound, was found to enhance immune responses in mice at specific doses. This study suggests isoprinosine may act as an immunopotentiator, warranting further investigation for its immune-boosting capabilities.

    Area of Science:

    • Immunology
    • Pharmacology
    • Virology

    Background:

    • Isoprinosine is an antiviral agent.
    • The immunomodulatory effects of isoprinosine require further elucidation.

    Purpose of the Study:

    • To investigate the impact of isoprinosine on mouse immune responses.
    • To determine the dose-dependent effects of isoprinosine on antibody production and lymphocyte proliferation.

    Main Methods:

    • Mice were administered varying doses of isoprinosine via intraperitoneal injection or oral administration.
    • Immune response was assessed by quantifying IgM- and IgG-spleen antibody-forming cells.
    • In vitro lymphocyte proliferation assays were conducted using phytohemagglutinin (PHA) and concanavalin A (Con A).

    Main Results:

    • Low to moderate doses of isoprinosine (50 µg/kg to 50 mg/kg) significantly increased antibody-forming cells.
    • High doses (up to 5 g/kg) and prolonged pretreatment did not impair immune responsiveness.
    • In vitro, isoprinosine augmented PHA- and Con A-induced lymphocyte proliferation.

    Conclusions:

    • Isoprinosine demonstrates immunopotentiating effects at specific dose ranges.
    • The compound does not appear to possess immunosuppressive properties.
    • Further research is recommended to explore isoprinosine's potential as an immunomodulator.
