Inflammation and the metabolic syndrome:: Role of angiotensin II and oxidative stress

Excess body weight, high blood pressure, and insulin resistance together have been denominated the metabolic syndrome. In, this, review, we analyze the potential role of angiotensin II (Ang II) and reactive oxygen species in Mediating inflammation in the metabolic syndrome. Ang II induces pro-inflammatory genes and other pro-inflamatory substances and increases oxidative stress that could damage, endothelium, myocardium, and renal tissue. Activation of nuclear, factor-kappa B and NAD(P)H oxidase are fundamental steps in these pro-inflammatory mechanisms in which intramitochondrial oxidative stress could play a critical role. This sequence of events might explain why reduction in Ang II synthesis by angiotensin converting enzyme inhibitors (ACEIs) and Ang II type I (ATI) receptor blockers (ARBs) have a protective effect against cardiovascular disease.
