IL6 and digestive system neoplasm: Tissue protection and reduced neutrophil infiltration during kidney ischaemia–reperfusion. Reduces tissue IL‐1β, IL‐6, and GRO1 mRNA levelsPrevents airway hyper‐responsiveness to methacholineReduces eosinophils and lymphocytes infiltrationProtects against vascular injury Reduces skin inflammationInhibits human neutrophil chemotaxis Reduces colon inflammation Inhibits VEGF‐induced EC migration and proliferation
