[Antibody diversity and network theory--a hypothesis].

H Hobler

    Immunitat Und Infektion
    |July 1, 1985
    PubMed
    Summary

    Antibody diversity develops through gene recombination and mutation, not germ-cell inheritance. Network theory explains immune regulation via anti-idiotypic antibodies, crucial for preventing self-attack and regulating non-immune cells.

    Area of Science:

    • Immunology
    • Molecular Biology
    • Genetics

    Context:

    • The immune system's antibody diversity is a complex trait.
    • Traditional views suggested germ-cell determination of antibody specificities.

    Purpose:

    • To explain the origin of antibody diversity.
    • To present the network theory of immune regulation.
    • To propose a mechanism for preventing autoimmunity.

    Summary:

    • Antibody diversity arises from somatic recombination and mutation, not predetermined germ-cell genes.
    • The network theory posits that antibody and lymphocyte populations regulate each other through idiotopes.
    • Anti-idiotypic antibodies, expressing autoantigen structures, are proposed to protect against autoimmune diseases.

    Impact:

    • Challenges the notion of germ-cell inheritance for antibody specificities.
    • Highlights the regulatory role of anti-idiotypic antibodies in immunity.
    • Suggests broader regulatory functions of the immune system beyond pathogen defense and surveillance.
