Cellular basis of the immune response.

J F Miller

    Acta Endocrinologica. Supplementum
    |January 1, 1975
    PubMed
    Summary

    Immune responses involve thymus-derived (T) cells and bursa-derived (B) cells, along with accessory cells. Their complex interactions and regulatory factors are crucial for understanding immune self-tolerance, like fetal survival during pregnancy.

    Area of Science:

    • Immunology
    • Cellular Biology

    Background:

    • Lymphocytes are key immune cells, categorized as T cells (cellular immunity) and B cells (humoral immunity).
    • Accessory cells (e.g., macrophages) support immune responses through antigen presentation and factor release.
    • Interactions between lymphocytes and accessory cells are vital for immune regulation.

    Purpose of the Study:

    • To elucidate the regulatory mechanisms governing cellular and humoral immunity.
    • To understand the role of T and B cell interactions and accessory cells in immune responses.
    • To explore how immune regulation facilitates fetal tolerance in pregnancy.

    Main Methods:

    • Review of existing literature on lymphocyte interactions and immune regulation.
    • Analysis of T cell-derived factors and their impact on immune cells.
    • Examination of B cell-produced antibodies and their regulatory functions.

    Main Results:

    • T cells produce factors that recruit inflammatory cells, activate macrophages, and modulate B cell responses.
    • B cell-produced antibodies can enhance or suppress immune responses, acting as a negative feedback.
    • Cellular interactions and secreted factors are critical for immune system regulation.

    Conclusions:

    • Understanding immune cell regulation is essential for explaining maternal-fetal tolerance.
    • The intricate interplay between T cells, B cells, and accessory cells governs immune homeostasis.
    • Immune regulation mechanisms are fundamental to preventing rejection of foreign tissues, including the fetus.
