TGF-β blockade significantly slows tumor growth through many mechanisms, including activation of CD8+ T-cells and macrophages. Here, we show that TGF-β blockade also increases neutrophil-attracting chemokines resulting in an influx of CD11b+/Ly6G+ tumor-associated neutrophils (TAN) that are hypersegmented, more cytotoxic to tumor cells, and express higher levels of pro-inflammatory cytokines. Accordingly, following TGF-β blockade, depletion of these neutrophils significantly blunts anti-tumor effects of treatment and reduces CD8+ T-cell activation. In contrast, in control tumors, neutrophil depletion decreases tumor growth and results in more activated CD8+ T-cells intra-tumorally. Together, these data suggest that TGF-β within the tumor microenvironment induces a population of TAN with a pro-tumor phenotype. TGF-β blockade results in the recruitment and activation of TAN with an anti-tumor phenotype.
