At all three time points, Emodin (50 mg/kg) reduced inflammatory cell (i.e. CD11b+ and F4/80+) recruitment, cytokine (i.e. TNFα, IL1α/β, IL6, CCL2, CXCL5) and pro-inflammatory enzymes (i.e. COX-2, NOS2) expression in the tumor microenvironment, while promoting recruitment of CD3+ T lymphocytes at 14 weeks. The gene discussed is IL1A; the disease is neoplasm.
