Suppressor cell activity in primary biliary cirrhosis.

R K Zetterman, J A Woltjen

    Digestive Diseases and Sciences
    |February 1, 1980
    PubMed
    Summary

    Patients with primary biliary cirrhosis (PBC) show a significant loss of inducible suppressor cell activity, which may explain the disease's progression. This immune dysfunction impacts mitogen response in PBC patients compared to healthy controls.

    Area of Science:

    • Immunology
    • Hepatology
    • Autoimmune Diseases

    Background:

    • Peripheral blood suppressor cells play a role in immune response modulation.
    • A lack of suppressor cell activity is observed in autoimmune diseases.
    • Primary biliary cirrhosis (PBC) is an autoimmune liver disease of unknown etiology.

    Purpose of the Study:

    • To investigate inducible suppressor cell activity in patients with primary biliary cirrhosis (PBC).
    • To compare suppressor cell activity in PBC patients with age- and sex-matched controls.

    Main Methods:

    • Assessed inducible suppressor cell activity in response to mitogens.
    • Compared results between PBC patients and control groups.

    Main Results:

    • PBC patients exhibited a significant deficit in inducible suppressor cell activity compared to controls (-4.5 +/- 8.0% vs. 43.7 +/- 7.8%).
    • No correlation was found between the loss of suppressor cell activity and clinical parameters in PBC patients.

    Conclusions:

    • Primary biliary cirrhosis patients demonstrate a marked deficiency in inducible suppressor cell activity.
    • This immune deficiency may contribute to the perpetuation and progression of primary biliary cirrhosis.
