Renal inflammation, autoimmunity and salt-sensitive hypertension

Abstract

1. The present article reviews the role of immune-competent cells infiltrating the kidney and their association with oxidative stress and renal angiotensin activity in the development of salt-sensitive hypertension. 2. We discuss changes in the pressure-natriuresis relationship resulting from renal inflammation and its improvement resulting from immunosuppressive treatment. 3. The potential role of T-cell-driven reactivity in sustaining the renal inflammation is examined in the light of accumulating evidence of autoimmune mechanisms in experimental and clinical hypertension.
