For instance, two of the biomarker candidates derived from immunoglobulins, IGHM and IGKV3‐20 are important mediators of the inflammatory responses which are reported to be the shared pathological mechanisms in a variety of vascular diseases, including atherosclerosis, abdominal aortic aneurysm, and arteritis (Chyatte et al, 1999; Chalouhi et al, 2012). The gene discussed is IGKV3-20; the disease is arteritis.
