Angiotensin News and Research

RSS

Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver. It plays an important role in the renin-angiotensin system.

New research could reduce risk of strokes in younger people

A drug that improves function of retinal blood vessels may be able to reduce the risk of stroke

The small study found that endothelial function is abnormal in eye blood vessels of patients who have early-stage hypertension, but that treatment with an angiotensin-receptor blocker (ARB) drug improves endothelial function. The endothelium is the lining of vessel walls and plays a key role in the vessels’ ability to relax and to constrict.
