Pocket ACEs: Discovering new function within an old player.

Area of Science:

• Biochemistry
• Immunology
• Physiology

Background:

• Angiotensin-converting enzyme (ACE) is primarily known for its role in the renin-angiotensin system (RAS).
• In the RAS, ACE converts angiotensin I to angiotensin II, regulating blood pressure and fluid balance.
• Recent research indicates ACE possesses functions beyond the RAS axis.

Purpose of the Study:

• To explore the non-canonical roles of ACE.
• To investigate ACE's involvement in hematopoiesis and immune system modulation.
• To elucidate ACE's functions both within and independent of the RAS.

Main Methods:

• Literature review of studies on ACE enzymatic activity.
• Analysis of research implicating ACE in various physiological systems.
• Examination of studies detailing ACE's role in hematopoiesis and immunity.

Main Results:

• ACE exhibits non-specific enzymatic activity.
• ACE plays a significant role in the development and modulation of hematopoiesis.
• ACE influences the immune system through both RAS-dependent and independent pathways.

Conclusions:

• ACE's functions extend beyond blood pressure regulation.
• ACE is a key modulator of both the hematopoietic and immune systems.
• Understanding ACE's diverse roles is crucial for comprehending its broader physiological impact.
