Taste Sensing Systems Influencing Metabolic Consequences

Abstract

Recent Findings

The taste information contributes to evaluate the quality and nutritional value of food before it is ingested, and thus, is essential for maintaining nutritive homeostasis within the body. Recent studies revealed that taste sensitivity is modulated by humoral factors such as hormones. Angiotensin II is a key hormone regulating sodium and water balance. Investigations of its involvement in the taste system revealed that angiotensin II suppresses the gustatory NaCl responses (amiloride-sensitive component) and enhances sweet taste sensitivity without affecting umami, sour, and bitter responses in mice.

Summary

These results suggest that taste modulation by angiotensin II may play important roles in maintaining electrolyte and glucose homeostasis.

Purpose of Review

This review focuses on the molecular mechanisms of salty taste perception and its modulation through the angiotensin II signaling to work out novel strategies to control food intake influencing metabolic consequences.
