IL33 and neoplasm: Additionally, mediators released by eosinophils, such as IL-5, IL-33, CCL11 (eotaxin-1), granulocyte–macrophage colony-stimulating factor (GM-CSF), thymic stromal lymphopoietin (TSLP), interferon-gamma (IFN-γ), and tumor necrosis factor-alpha (TNF-α), play a significant role in the response of eosinophils to tumor cells [31,69,70].
