    Ascorbic acid (vitamin C) enhances immune cell functions, including neutrophil activity and antimicrobial responses. It supports the body's defense mechanisms against pathogens and oxidative stress.

    Area of Science:

    • Immunology
    • Nutritional Science
    • Biochemistry

    Background:

    • Ascorbic acid, commonly known as vitamin C, is a vital nutrient with known antioxidant properties.
    • Its precise roles in immune function, particularly concerning cellular responses, require detailed examination.

    Purpose of the Study:

    • To review the multifaceted role of ascorbic acid in the immune system.
    • To elucidate its impact on antimicrobial activity, interferon production, and both humoral and cellular immune responses.

    Main Methods:

    • Literature review of studies investigating ascorbic acid's effects on immune cells and functions.
    • Analysis of research on ascorbic acid's influence on neutrophil behavior and antimicrobial mechanisms.

    Main Results:

    • Ascorbic acid enhances neutrophil functions such as chemotaxis and particle ingestion.
    • It plays a role in non-oxidative killing, protects against oxidative damage, and modulates the halide-peroxide-myeloperoxidase system.
    • Ascorbic acid stimulates the hexose monophosphate shunt, crucial for cellular defense processes.

    Conclusions:

    • Ascorbic acid significantly contributes to immune defense by modulating key neutrophil functions.
    • It bolsters the body's capacity to combat infections and mitigate oxidative stress through various biochemical pathways.
