  • Title: In vitro IgE synthesis induced by human T cell clones in normal B cells and its suppression by heterogenous T cell populations.
    Author: Romagnani S, Del Prete GF, Maggi E, Ricci M.
    Journal: Int Arch Allergy Appl Immunol; 1987; 82(3-4):411-3. PubMed ID: 3106239.
    Abstract:
    Thirty-four out of 119 human T cell clones established from tonsillar or peripheral blood T cell suspensions of 3 nonallergic individuals were able to induce normal B cells to synthesize remarkable amounts of IgE in vitro. The activity of these clones was apparently mediated by triggering of the monomorphic molecular complex CD3 immediately before or during their incubation with the target B cells. The addition to the cultures of mitogen-stimulated autologous unfractionated T cells inhibited in a dose-dependent fashion, the T cell clone induced IgE, but not IgG, synthesis.
