Cytosol levels of cytokines [interleukins 1b, 6, 8 (IL-1b, 6, 8), tumor necrosis factor-alpha (TNF-alpha)] in aneurysm walls were evaluated in a prospective non-randomized study of 57 patients.
In this study, we demonstrate that matrix metalloproteinase-1 (MMP-1), a collagenase expressed in atherosclerosis and aneurysms but not in the normal vessel wall, is induced in the aortic endothelium of rabbits exposed to cigarette smoke.
Investigation of the molecular mechanisms preceding PDE4 inhibitor-induced vasculopathy in rats: tissue inhibitor of metalloproteinase 1, a potential predictive biomarker.
More pronounced inflammatory changes and higher cytosol cytokine levels [IL6 (p<0.001), IL8 (p<0.0003) and TNFalpha (p<0.002)] were found in the walls of ruptured aneurysms than in the asymptomatic aneurysms.

The systemic expressions of MMP-2 and MMP-9 were strongly associated with vasculo-Behçet's disease, particularly aneurysmatic involvement, suggesting their pathogenetic roles in vasculo-Behçet's disease complicated with aneurysm formation.
This case suggested that the COL3A1 gene could be one of etiologically linked genes in isolated vasculopathies such as aortic dissected aneurysm or CAD, although being rare.
