IL1B and neoplasm: Macrophage density was lower & tumor growth was delayed in CCR6 deficient mice compared to wild type miceMacrophage accumulation was greater in response to CCL20 than to CCL2Macrophage depletion led to reduced tumor growthHigher macrophage density in wild type mice accompanied by increased expression of CCL2, IL‐1, IL6, but not TNFα, compared to CCR6 deficient miceExpression of CCR6 correlated with CD163, CCL2, IL‐1α & TNFα
