CCL7 and neoplasm: DAMPs released by irradiated cancer cells can also activate the tumour vasculature endothelium to upregulate cell adhesion molecules—such as ICAM‐1, VCAM‐1 and E‐selectin—and the production of chemoattractants—such as IL‐6, CXCL1, CXCL2, CCL7, CXCL8, CCL2, IL‐1β and G‐CSF.24, 38, 75, 91
