摘要


Recent data have demonstrated that chronic inflammation is a crucial component of tumor initiation and progression. We previously reported that immature myeloid-derived suppressor cells (MDSCs) with immunosuppressive activity toward effector T cells were expanded in experimental chronic inflammation. We hypothesized that elevated levels of MDSCs, induced by chronic inflammation, may contribute to the progression of tumor growth. Using the Ehrlich carcinoma animal model, we found increased tumor growth in mice with chronic adjuvant arthritis, which was accompanied by a persistent increase in the proportion of splenic monocytic and granulocytic MDSCs expressing CD62L (L-selectin), when compared to tumor mice without adjuvant arthritis. Depletion of inflammation-induced MDSCs resulted in decreased tumor growth. In vitro studies demonstrated that increased expression of CD62L by MDSCs was mediated by TNFα, elevated concentrations of which were found in tumor mice subjected to chronic inflammation. Moreover, the addition of exogenous TNFα markedly enhanced the suppressive activity of bone marrow-derived MDSCs, as revealed by the ability to impair the proliferation of CD8+ T cells in vitro. This study provides evidence that chronic inflammation may promote tumor growth via induction of CD62L expression by MDSCs that can facilitate their migration to tumor and lymph nodes and modulation of their suppressor activity.
