Ion channels in lymphocytes.

K G Chandy, T E DeCoursey, M D Cahalan

    Journal of Clinical Immunology
    |January 1, 1985

    Summary
    This summary is machine-generated.

    Immune cells like lymphocytes use ion channels for activation. Potassium channels are vital for T-lymphocyte proliferation, and calcium channels support antibody production, revealing new insights into immune cell function.
