    Area of Science:

    • Immunology
    • Virology
    • Molecular Biology

    Background:

    • Interferon-gamma (IFN-gamma) is a crucial cytokine in the immune response.
    • Understanding its structure and function is key to developing new therapies.
    • Comparison with type I interferons (IFN-alpha, IFN-beta) aids in elucidating its unique properties.

    Purpose of the Study:

    • To provide an overview of interferon-gamma (IFN-gamma) structure and biological activities.
    • To highlight recent findings with recombinant human and murine IFN-gamma.
    • To compare type II IFN-gamma with type I interferons (IFN-alpha, IFN-beta).

    Main Methods:

    • Review of existing literature on IFN-gamma.
    • Presentation of the amino acid sequence of human IFN-gamma.
    • Analysis of experimental results with recombinant IFNs.

    Main Results:

    • IFN-gamma demonstrates antiviral, cytostatic, and cytotoxic effects.
    • It enhances immune cell functions, including macrophage activation and natural killer cell activity.
    • Evidence for in vivo anti-tumor activity and interactions with interleukin-2 is discussed.

    Conclusions:

    • IFN-gamma possesses diverse biological activities with significant therapeutic implications.
    • Further research into the molecular mechanisms of IFN-gamma action is warranted.
    • IFN-gamma represents a promising candidate for anti-cancer and anti-viral therapies.
