[Immune dysfunctions in aging (author's transl)].

M Schlaak, W L Gross

    Immunitat Und Infektion
    |October 1, 1977
    PubMed
    Summary
    This summary is machine-generated.

    As people age, their cell-mediated immunity declines, particularly T-cell function, increasing susceptibility to infectious diseases like tuberculosis and viral hepatitis.

    Area of Science:

    • Immunology
    • Gerontology
    • Infectious Diseases

    Context:

    • Age-related changes in immune function are linked to increased disease incidence.
    • Humoral immunity (immunoglobulins) generally increases with age.
    • Cell-mediated immunity shows a progressive decline in the elderly.

    Purpose:

    • To discuss the pathogenic role of immune functions in age-related diseases.
    • To investigate the age-dependence of cell-mediated immunity.
    • To explore the impact of T-cell subpopulation alterations on immune response.

    Summary:

    • Immune system components like immunoglobulins increase with age.
    • Delayed type hypersensitivity reactions and cell-mediated immunity significantly decrease in older adults.

  • Age-correlated alterations in T-cell subpopulations are key factors in reduced cell-mediated immunity.

    • Impact:

    • Reduced cell-mediated immunity in the elderly contributes to increased morbidity and mortality from infectious diseases.
    • Understanding these immune changes is crucial for managing age-related health risks.
    • This research highlights the importance of T-cell function in immune defense against specific pathogens in older populations.
