Angiotensin is a peptide hormone that plays a key role in regulating blood pressure and fluid balance in the body. Research in this area focuses on understanding the mechanisms by which angiotensin is produced, processed, and regulated, as well as its effects on various physiological processes. This research helps in the development of treatments for conditions such as hypertension, heart failure, and kidney disease, which are closely linked to dysregulation of the renin-angiotensin system. Additionally, angiotensin research also explores the potential use of angiotensin receptor blockers and angiotensin-converting enzyme inhibitors as therapeutic agents for these conditions.
