    Area of Science:

    • Immunology
    • Pharmacology

    Background:

    • Carrageenan, an algal polysaccharide, has demonstrated significant immunomodulatory effects since 1972.
    • Numerous studies confirm carrageenan's ability to suppress various immune responses, including antibody production, graft rejection, delayed hypersensitivity, and anti-tumor immunity.

    Purpose of the Study:

    • To review and discuss the multifaceted effects of carrageenan on immune responses.
    • To evaluate carrageenan's utility as a research tool for investigating immune mechanisms.

    Main Methods:

    • Analysis of existing literature on carrageenan's biological effects.
    • Focus on carrageenan's selective cytotoxic impact on mononuclear phagocytes.
    • In vitro and in vivo experimental data evaluation.

    Main Results:

    • Carrageenan induces profound suppression of cellular and humoral immunity.
    • Carrageenan exhibits a selective cytotoxic effect on mononuclear phagocytes.
    • This property has led to its use in dissecting the role of phagocytes in immune reactivity.

    Conclusions:

    • Carrageenan is a potent immunomodulatory agent with significant immunosuppressive capabilities.
    • Carrageenan serves as a valuable tool for researchers studying the role of mononuclear phagocytes in immune responses.
    • Further research utilizing carrageenan can enhance understanding of immune system mechanisms.
