The renin-angiotensin aldosterone system (RAAS) regulates adiponectin levels in humans. Angiotensin II infusion decreased adiponectin, while RAAS blockade increased it, suggesting therapeutic potential.
Area of Science:
- Endocrinology
- Cardiovascular Physiology
Background:
- Adiponectin exhibits anti-inflammatory and vascular protective properties, potentially improving insulin sensitivity.
- Animal studies indicate the renin-angiotensin aldosterone system (RAAS) influences adiponectin regulation.
Purpose of the Study:
- To investigate the role of the RAAS in regulating human adiponectin levels in vivo.
- To examine the effects of physiological and pharmacological RAAS modulation on plasma adiponectin.
Main Methods:
- Thirty-five healthy males underwent low-sodium and high-sodium diet periods.
- Plasma adiponectin was measured at baseline and during angiotensin II infusion.
- Effects of enalapril (ACE inhibition) on adiponectin were assessed during high-sodium intake.
Main Results:
- High-sodium diet (suppressing RAAS) significantly increased adiponectin levels.
- Angiotensin II infusion markedly decreased adiponectin concentrations.
- Enalapril treatment led to a significant increase in adiponectin.
Conclusions:
- RAAS modulation significantly impacts plasma adiponectin concentrations in humans.
- Lower adiponectin levels were observed under conditions of high angiotensin II activity.
- RAAS blockade warrants further investigation for treating hypoadiponectinemia.

Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
