title: Nucleoside-specific suppression in MRL/MP +/+ mice.
abstract: The induction of nucleoside-specific nonresponsiveness was further studied in the autoimmune strain MRL/MP +/+ (MRL/n). Experiments were undertaken to determine (i) whether nucleoside-conjugated spleen cells are able to induce specific nonresponsiveness to T-dependent nucleoside antigens in MRL/n mice, and (ii) whether periodic treatment with nucleoside-conjugated spleen cells would retard the development of spontaneous anti-DNA antibodies and associated indicators of autoimmunity. The results show that nonresponsiveness to nucleoside antigens is inducable in male, but not in female, MRL/n mice. Nonresponsiveness in male MRL/n was transferable and mediated by T cells. Treatment of male MRL/n mice with nucleoside-conjugated spleen cells (NSC) appeared to attenuate the progress of autoimmune symptoms in experimental animals. These results are discussed in the context of recent studies exploring the etiology of autoantibody production and the loss of self-tolerance in murine models of autoimmunity.
