Angiotensin Ⅱ and receptors in rheumatoid arthritis / 中国药理学通报

ABSTRACT

Angiotensin Ⅱ and type 1 receptor ( AT1R) are ab-solutely therapeutic targets in the hypertension and cardiovascular disease, and angiotensin Ⅱ gets involved in monocytes chemo-taxis and migration, T lymphocytes activation and proliferation, Th1 and Th17 immune function, and synoviocytes apoptosis inhi-bition in patients with rheumatoid arthritis ( RA) through binding to AT1R in the autocrine and/or paracarine manner. Drugs that limit angiotensin Ⅱ production by angiotensin converting enzyme inhibitors ( ACEIs) or blockade of angiotensin Ⅱ-AT1R action by AT1R blocker ameliorate immune and inflammation responses in RA patients. Additionally, angiotensin Ⅱ type 2 receptor (AT2R) expression increases in RA and experimental model, and activation of AT2R exerts a therapeutic effect on adjuvant-in-duced arthritis. AngiotensinⅡand its receptors in RA and auto-immune diseases are retrospectively reviewed in this paper.
