In this issue of Blood, Neven et al report that a third of the patients with interleukin-10 receptor (IL-10R) deficiency develop B-cell lymphomas in the first decade of their life. The lymphomas uniformly contained amplifications of c-rel, activation of inflammatory nuclear factor kB (NF-kB) target genes, and a defective intratumoral CD81 T-cell tumor immunosurveillance. © 2013 by The American Society of Hematology.

Human cancer is characterized by deficits in antigen-specific immunity and intratumoral CD8(+) T cells. On the other hand, inflammatory macrophages and mediators of chronic inflammation are highly prevalent in patients with late-stage cancer. Intratumoral T-cell deficiency and chronic inflammation have been linked independently to a poor prognosis in patients with cancer, and therapeutic approaches to overcome either pathology separately are in clinical testing. The anti-inflammatory cytokine interleukin (IL)-10 suppresses macrophage and proinflammatory Th17 T-cell responses by inhibiting the inflammatory cytokines IL-6 and IL-12/23. Corroborating the anti-inflammatory action of IL-10, deficiency in IL-10 leads to a stimulation of inflammatory responses and inflammatory bowel disease. The anti-inflammatory role of IL-10 fostered the assumption that IL-10 undermines the immune response to cancer. However, mice and humans deficient in IL-10 signaling develop tumors spontaneously and at high rates. Overexpression of IL-10 in models of human cancer or treatment with a pegylated IL-10 (PEG-IL-10) led to tumor rejection and long-lasting tumor immunity. IL-10 stimulates cytotoxicity of CD8(+) T cells and the expression of IFN-γ in CD8(+) T cells. IL-10-induced tumor rejections are dependent on the expression of IFN-γ and granzymes in tumor-resident CD8(+) T cells and the upregulation of MHC molecules. These findings reconcile earlier clinical data, which showed that recombinant IL-10 increased IFN-γ and granzymes in the blood of treated individuals. PEG-IL-10 is therefore a unique therapeutic agent, which simultaneously stimulates antitumor immunity and inhibits tumor-associated inflammation. ©2014 AACR. Source
