B cell growth and differentiation factors.

M Howard, K Nakanishi, W E Paul

    Immunological Reviews
    |April 1, 1984
    PubMed
    Summary

    T lymphocytes regulate B cell responses through soluble factors, formerly called T cell-replacing factor (TRF). These complex, antigen-non-specific factors control B cell activation, proliferation, and differentiation, offering hope for understanding B cell immunoregulation.

    Area of Science:

    • Immunology
    • Cellular Biology

    Background:

    • T lymphocytes play a crucial role in regulating B cell responsiveness.
    • Early research identified a soluble product, T cell-replacing factor (TRF), involved in this regulation.
    • Recent findings reveal a more complex system of soluble factors governing B cell immunity.

    Purpose of the Study:

    • To review the evolving understanding of soluble factors regulating B cell immunity.
    • To highlight the complexity beyond the initial concept of T cell-replacing factor (TRF).
    • To discuss the implications for understanding B cell immunoregulation.

    Main Methods:

    • Review of existing scientific literature on T cell-B cell interactions.
    • Analysis of studies identifying and characterizing soluble regulatory factors.
    • Synthesis of current knowledge on B cell activation, proliferation, and differentiation.

    Main Results:

    • The regulation of B cell immunity involves a diverse array of antigen-non-specific, genetically unrestricted soluble factors.
    • These factors influence all key aspects of B cell function: activation, proliferation, and differentiation.
    • The initial concept of TRF has evolved to encompass this complex network of immunoregulatory molecules.

    Conclusions:

    • Significant progress has been made in understanding the soluble factors that regulate B cell immunity.
    • While many questions remain, the complexity of these factors is becoming clearer.
    • Further research into these factors and their mechanisms holds promise for elucidating the basis of B cell immunoregulation.
