CXCL5 and aortic aneurysm: Chemokine genes upregulated in aneurysms included Ccl21 and Ccl19 (which attract T cells and dendritic cells), Ccl7 (attracts monocytes), Cxcl9 (attracts T cells), Cxcl12 (attracts lymphocytes) and Cxcl5 (attracts neutrophils), suggesting that all these inflammatory cell types are recruited to mouse aortic aneurysms.
