  • Title: The effect of T cell-derived cytokines on B cell motility in vitro.
    Author: Clinchy B, Elenström C, Möller G.
    Journal: Cell Immunol; 1993 Jan; 146(1):62-70. PubMed ID: 8425231.
    Abstract:
    We have investigated the ability of interleukin-1 (IL-1), IL-2, IL-3, IL-4, IL-5, IL-6, and interferon-gamma (IFN-gamma) to induce motility in murine, splenic B lymphocytes. Two parameters of cellular locomotion were studied, namely acquisition of motile morphology (polarization) and in vitro migration through polycarbonate filters. Of the tested cytokines, only IL-4 gave a strong motile response among B cells. At the optimal concentration of 3 ng/ml, IL-4 induced polarization in 10-20% of the B cells within 30 min and in up to 40% after overnight exposure. The same amount IL-4 present in a microchemotaxis chamber stimulated migration through polycarbonate filters after overnight incubation in up to 15% of the input B cells. IFN-gamma could also induce some degree of polarization and migration, but only after 19 hr of exposure and to a much lesser extent than IL-4.
