Aspects of lymphocyte function in Behçet's disease.

S Haim, T Mekori, J D Sobel

    Dermatologica
    |January 1, 1976
    PubMed
    Summary

    This study investigated lymphocyte function in Behçet's disease, finding reduced T and B lymphocytes but normal T cell response to mitogens, suggesting potential hyperreactivity in active disease.

    Area of Science:

    • Immunology
    • Rheumatology
    • Cellular Biology

    Background:

    • Behçet's disease is a chronic inflammatory disorder.
    • Immune system dysregulation is implicated in Behçet's disease pathogenesis.
    • Understanding lymphocyte function is crucial for Behçet's disease research.

    Purpose of the Study:

    • To investigate in vitro lymphocyte function in patients with active Behçet's disease.
    • To assess T lymphocyte and B lymphocyte numbers and function.
    • To evaluate T lymphocyte response to mitogenic stimulation.

    Main Methods:

    • Rosette formation technique was used to enumerate T and B lymphocytes.
    • In vitro lymphocyte transformation assays were performed.
    • Serum immunoglobulin and complement levels were measured.

    Main Results:

    • A decrease in T lymphocytes and a more pronounced decrease in B lymphocytes were observed.
    • Despite reduced numbers, T lymphocytes showed normal transformation response to mitogens.
    • Spontaneous blastogenesis was noted in two patients prior to mitogen addition.
    • Serum immunoglobulin and complement levels were within normal ranges.

    Conclusions:

    • Patients with active Behçet's disease exhibit reduced T and B lymphocyte counts.
    • T lymphocytes may possess normal or potentially hyperreactive function despite lower numbers.
    • Further research is needed to elucidate the role of lymphocyte alterations in Behçet's disease.
