Cell-mediated immunity in nutritional imbalance.

R K Chandra

    Federation Proceedings
    |November 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Nutritional imbalance, including undernutrition and overnutrition, significantly impairs cell-mediated immunity. Deficiencies in nutrients like zinc and pyridoxine, and conditions like obesity, disrupt immune responses, impacting overall health.

    Area of Science:

    • Immunology
    • Nutrition Science
    • Cellular Biology

    Background:

    • Nutritional status profoundly impacts immune system function.
    • Both undernutrition and overnutrition can lead to significant immune dysregulation.
    • Cell-mediated immunity is particularly sensitive to nutritional imbalances.

    Purpose of the Study:

    • To review the effects of nutritional imbalance on cell-mediated immunity.
    • To explore the mechanisms underlying nutritional immunomodulation.
    • To highlight the clinical significance of these immune alterations.

    Main Methods:

    • Review of existing literature on nutrition and immunity.
    • Analysis of studies investigating T lymphocyte function and immune cell populations.
    • Examination of specific nutrient deficiencies and their immunologic consequences.

    Main Results:

    • Protein-energy malnutrition impairs delayed hypersensitivity and reduces T lymphocytes.
    • Nutrient deficiencies (e.g., zinc, pyridoxine) and obesity alter cell-mediated immunity.
    • Intrauterine growth retardation leads to long-lasting deficits in cell-mediated immunity.

    Conclusions:

    • Nutritional status is a critical determinant of cell-mediated immune function.
    • Imbalances in nutrition can lead to impaired immune responses and increased susceptibility to disease.
    • Understanding these links is crucial for managing various systemic disorders.
