The roles of cytokines, inflammation and immunity in vascular diseases.

Abstract

Recent findings regarding the roles of cytokines, inflammation and immunity during the development of atherosclerosis were reviewed. Especially, the relationships among pro-inflammatory cytokines such as interleukin (IL)-1, IL-18 and osteopontin, and anti-inflammatory cytokines such as IL-1 receptor antagonist, IL-10 and IL-18 binding protein to inflammation and atherosclerosis were investigated and are described in detail. In addition, helicobacter pylori and C pneumoniae infections to inflammations regarding the persistence of inflammation have been pointed out. A pro-inflammatory genotype or haplotype and toll-like receptors have been shown to be involved in human atherosclerosis. Atherosclerosis might therefore be a specific form of the chronic inflammatory process. In addition to hyperlipidemia, infections, cytokines and immunity might also be involved in the development of atherosclerosis. Certain treatments that reduce coronary risk also limit inflammation. Statins possess multiple pleiotropic effects such as an anti-inflammatory effect in addition to a lipid-lowering effect.
