Abstract

Inflammation has recently proven to be associated with the pathogenesis of atherosclerosis and inflammatory genes are good candidates for the risk of developing atherosclerosis. The early phase of atherosclerosis involves the recruitment of inflammatory cells from the circulation and their transendothelial migration. This process is mainly mediated by cellular adhesion molecules, which are expressed by the vascular endothelium and by circulating leukocytes in response to several inflammatory stimuli. Adhesion of circulating cells to the arterial surface is among the first detectable events in atherogenesis. Cellular adhesion molecules, expressed by the vascular endothelium and by circulating leukocytes, mediate cell recruitment and their transendothelial migration. Platelet endothelial cellular adhesion molecule-1 (PECAM-1/CD31), involved in this migration, has been associated with the developmental course of atherosclerosis. Studies have investigated an association between coronary heart disease (CHD) and single nucleotide polymorphisms (SNP) located in functionally important domains of the PECAM-1/CD31 gene, with contrasting results. In particular, we previously analyzed for the following PECAM-1/CD31 SNP: Val125Leu, Asn563Ser,and Gly670Arg. The frequency of the Gly670Arg polymorphism was significantly higher in patients withmyocardial infarction (MI),whereas the frequencies of the other two SNP Leu125Val and Ser563Asn) were not significantly different between patients and controls. To check the validity of our results, we have analyzed the distribution of these SNP in centenarian men (age >99) from our homogeneous Sicilian population, since our previous studies have demonstrated that alleles associated with MI susceptibility are not included in the genetic background favoring longevity. We showed, as regard to polymorphisms of PECAM-1/CD31, that there were no significant differences between male patients affected by MI, male controls, and male centenarians. According to our hypothesis present results seemingly do not support a role for these SNP in conferring the susceptibility to MI at least in this Italian population.
