title: Suppression of IgE antibody production in SJL mice. I. Nonspecific suppressor T cells.
abstract: High titer and persistent antihapten IgE production in SJL mice can be obtained using appropriate immunization and radiation. Nonirradiated mice rapidly terminate this antihapten IgE production. Radiation was not necessary to prolong antihapten IgE production in other strains of mice. Termination can be obtained even in irradiated SJL mice by transferring normal SJL spleen cells. That the suppressor cells are T cells is shown by using thymocytes or cells treated with anti-Thy 1.2 and complement. No appreciable suppressive effect by normal spleen cells could be demonstrated on IgG1 production in SJL mice. The characteristic of low and transient IgE antibody response in SJL mice is inherited as a recessive trait controlled by a single Mendelian autosomal gene and is not linked to the H-2-gene complex. This characteristic does not depend on the infectivity of Nippostrongylus brasiliensis, the effect of anticarrier antibody, or the recognition of antigen.
