Angiotensin 1-7 is primarily used in research and therapeutic contexts due to its role in the renin-angiotensin system. It has shown potential in treating cardiovascular diseases by counteracting the effects of Angiotensin II, such as vasoconstriction and hypertension. It promotes vasodilation, reduces inflammation, and may improve heart function. Additionally, it is being studied for its potential benefits in managing kidney diseases, diabetes, and pulmonary hypertension. Its anti-fibrotic and anti-proliferative properties make it a promising candidate for further clinical applications.
