Inflammatory reaction versus endogenous peroxisome proliferator-activated receptors expression, re-exploring secondary organ complications of spontaneously hypertensive rats.

Background: The chronic pathological changes in vascular walls of hypertension may exert destructive effects on multiple organ systems. Accumulating evidence indicates that inflammatory reactions are involved in the pathological changes of hypertension. Three peroxisome proliferator-activated receptors (PPARs) have been identified: PPARalpha, PPARbeta/delta, and PPARgamma, all of which have multiple biological effects, especially the inhibition of inflammation.

Inflammation of different tissues in spontaneously hypertensive rats.

The hypertension is one of chronic vascular diseases, which often implicates multiple tissues causing stroke, cardiac hypertrophy, and renal failure. A growing body of evidence suggests that inflammatory mechanisms are important participants in the pathophysiology of hypertension. In this study, the inflammatory status of these tissues (kidney, liver, heart, and brain) in spontaneously hypertensive rats (SHR) was analyzed and its molecular mechanism was explored.
