Early B lymphocytes in man

P F Conte, M Boccadoro, A Pileri

    Experientia
    |September 15, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Researchers identified a unique B lymphocyte subpopulation in humans that cannot re-express immunological receptors after antibody challenge. This discovery sheds light on early B cell behavior and immune responses.

    Area of Science:

    • Immunology
    • Cell Biology
    • Hematology

    Background:

    • B lymphocytes are crucial for adaptive immunity, producing antibodies.
    • The ability of B cells to re-express receptors is vital for immune memory and regulation.

    Purpose of the Study:

    • To confirm the existence of a B lymphocyte subpopulation in humans with impaired receptor re-expression.
    • To characterize these early B lymphocytes in various biological samples.

    Main Methods:

    • Analysis of peripheral blood and cord blood samples.
    • Utilized anti-idiotypic sera for B lymphocyte identification.
    • Studied B cells from a myeloma patient.

    Main Results:

    • Confirmed the presence of B lymphocytes that fail to re-express immunological receptors post-antibody challenge.

  • These cells were identified in peripheral blood, cord blood, and in a myeloma patient's blood.

    • Conclusions:

    • A distinct subpopulation of early B lymphocytes exists in humans with a limited capacity for receptor re-expression.
    • This finding has implications for understanding B cell development and immune dysregulation.
