Though long-time survivors could not be generated by ICB treatment when therapy was done in the absence of T cells, the survival times were still significantly prolonged as compared with untreated mice (figure 3D)
Though long-time survivors could not be generated by ICB treatment when therapy was done in the absence of T cells, the survival times were still significantly prolonged as compared with untreated mice (figure 3D). effect was dependent on cytokine-induced senescence in malignant B cells. The proinflammatory cytokines interferon- (IFN-) and tumor necrosis factor (TNF) were necessary for the survival benefit as well as for senescence induction in the -MYC model. Antibody therapy improved T-cell functions such as cytokine production, and long-time survivors were only observed in the presence of T cells. Yet, NK cells also had a pronounced effect on therapy-induced delay of tumor growth. Antibody treatment enhanced numbers, proliferation and IFN- expression of NK cells in developing tumors. The therapeutic effect was fully abrogated only after depletion of both,…
