Protein-kinase-C-δ-knockout mice show attenuated inflammation in models of abdominal aortic aneurysm with reduced CCL7 expression in the abdominal aortic artery [50]. Taken together, it seems that CCL7 is inducible and may be involved in the pathological process of hypertension and vascular remodeling. Here, CCL7 is linked to abdominal aortic aneurysm.
