Angiotensin-1-7 is a peptide hormone that is part of the renin-angiotensin system, which plays a key role in regulating blood pressure and fluid balance in the body. Angiotensin-1-7 is a vasodilator and is involved in counterbalancing the vasoconstrictive effects of other components of the renin-angiotensin system, such as angiotensin II. Research on angiotensin-1-7 has focused on its potential therapeutic benefits for conditions such as hypertension, heart failure, and kidney disease. Studies have shown that angiotensin-1-7 may have protective effects on the cardiovascular system and can improve outcomes in certain disease states. Further research is ongoing to explore the full potential of angiotensin-1-7 as a target for novel therapeutics.
