Angiotensin-converting enzyme 2: central regulator for cardiovascular function

Area of Science:

• Cardiovascular Physiology
• Neuroendocrinology
• Renal Physiology

Background:

• Angiotensin-converting enzyme 2 (ACE2) is a key component of the renin-angiotensin system (RAS).
• ACE2 demonstrates protective effects in peripheral tissues, with potential therapeutic applications for RAS-related diseases.
• The central nervous system (CNS) role of ACE2 has been less understood until recent advancements.

Purpose of the Study:

• To review and summarize recent findings on the central effects of ACE2.
• To elucidate the role of ACE2 in the central regulation of cardiovascular function.
• To highlight ACE2's potential in managing hypertension and related disorders.

Main Methods:

• Literature review of recent studies on central ACE2.
• Analysis of experimental data on brain ACE2 interactions with RAS components.
• Examination of studies investigating ACE2's impact on baroreflex, autonomic function, and oxidative stress.

Main Results:

• Central ACE2 interacts with key RAS components, including ACE, angiotensin II, and the angiotensin II type 1 receptor.
• ACE2 in the brain protects baroreflex and autonomic function.
• Brain ACE2 stimulates nitric oxide release, reduces oxidative stress, and prevents or attenuates hypertension.

Conclusions:

• ACE2 plays a critical role in the central regulation of cardiovascular function.
• Evidence supports ACE2's neuroprotective and antihypertensive effects within the CNS.
• Further research into central ACE2 mechanisms may reveal novel therapeutic strategies for cardiovascular diseases.
