    Insights

    Lentinan treatment significantly increased superoxide radical production and superoxide dismutase (SOD) activity in mouse macrophages. This enhanced SOD activity in activated macrophages correlated with a reduction in lipid peroxidation.

    Area of Science:

    • Immunology
    • Biochemistry
    • Cell Biology

    Background:

    • Macrophages play a crucial role in the immune response.
    • Superoxide radicals are key signaling molecules in cellular processes.
    • Lipid peroxidation is a marker of oxidative stress.

    Purpose of the Study:

    • To investigate the effect of Lentinan on macrophage activation.
    • To examine the impact of Lentinan on superoxide radical production and SOD activity.
    • To determine the relationship between SOD activity and lipid peroxidation in macrophages.

    Main Methods:

    • Murine macrophage cell line (C4M phi) was cultured in suspension.
    • Cells were treated with varying concentrations of Lentinan.
    • Superoxide radical production and SOD activity were measured.
    • Lipid peroxidation levels were assessed.

    Main Results:

    • Lentinan treatment led to a significant increase in superoxide radical production.
    • Superoxide dismutase (SOD) activity was markedly elevated in Lentinan-treated macrophages.
    • Activated macrophages exhibited decreased lipid peroxidation, correlating with increased SOD activity.

    Conclusions:

    • Lentinan effectively modulates macrophage activity.
    • Enhanced SOD activity is a key response to Lentinan in macrophages.
    • Lentinan may protect macrophages from oxidative stress by increasing SOD activity.
