Angiotensin Receptors: Structure, Function, Signaling and Clinical Applications

Area of Science:

• Biochemistry
• Physiology
• Pharmacology

Background:

• The Renin Angiotensin System (RAS) involves angiotensinogen, processed into peptides that signal through specific receptors.
• Key receptors include angiotensin type 1 (AT1), type 2 (AT2), MAS, and angiotensin IV binding sites.
• These receptors regulate cardiovascular, neurological, renal, and endothelial functions, impacting cell proliferation and inflammation.

Purpose of the Study:

• To review the roles of angiotensin receptors in physiological regulation.
• To highlight their significance as therapeutic targets in various diseases.
• To discuss the current focus on AT1 receptor-targeted drugs.

Main Methods:

• Literature review of Renin Angiotensin System (RAS) components and angiotensin receptors.
• Analysis of physiological functions regulated by angiotensin peptides and their receptors.
• Examination of current therapeutic strategies targeting angiotensin receptors.

Main Results:

• Angiotensin receptors (AT1, AT2, MAS, AngIV sites) mediate diverse physiological responses.
• AT1 receptor blockers are established treatments for hypertension, heart failure, and vascular diseases.
• Research focus is predominantly on AT1 receptor-targeted therapies over others.

Conclusions:

• Angiotensin receptors play critical roles in maintaining physiological homeostasis.
• Targeting angiotensin receptors, particularly AT1, offers significant therapeutic potential for cardiovascular and renal diseases.
• Further research into AT2, MAS, and AngIV receptors may reveal additional therapeutic avenues.
