Salivary PYY: A Putative Bypass to Satiety
Peptide YY(3-36) is a satiation hormone released postprandially into the bloodstream from L-endocrine cells in the gut epithelia. In the current report, we demonstrate PYY(3-36) is also present in murine as well as in human saliva. In mice, salivary PYY(3-36) derives from plasma and is also synthesized in the taste cells in taste buds of the tongue. Moreover, the cognate receptor Y2R is abundan...
متن کاملThe putative satiety hormone PYY is raised in cardiac cachexia associated with primary pulmonary hypertension.
W eight loss greater than 6% independently correlates with reduced survival in patients with congestive heart failure (CHF). Cardiac cachexia is a gradual and graded process, with wasting affecting muscle, bone, adipose tissue and the heart. Reduced appetite has been proposed as a important factor for weight loss caused by cardiac cachexia. The mechanism of cardiac cachexia remains largely uncl...
متن کاملWhen gut fermentation controls satiety: A PYY story
Gut microbiota is now considered to be an important regulator of body weight. With approximately 10 million genes [1], the gut metagenome is certainly hiding numerous mechanisms involved in the control of body weight and the consequent metabolic disease [2]. Among them, bacterial enzymes fermenting non-digestible dietary fibers into the short chain fatty acids (SCFA) acetate, propionate, and bu...
متن کاملFermentable carbohydrate stimulates FFAR2-dependent colonic PYY cell expansion to increase satiety
OBJECTIVE Dietary supplementation with fermentable carbohydrate protects against body weight gain. Fermentation by the resident gut microbiota produces short-chain fatty acids, which act at free fatty acid receptor 2 (FFAR2). Our aim was to test the hypothesis that FFAR2 is important in regulating the beneficial effects of fermentable carbohydrate on body weight and to understand the role of gu...
متن کاملSatiety, but not total PYY, is increased with continuous and intermittent exercise
OBJECTIVE This study determined the hormonal and subjective appetite responses to exercise (1-h continuous versus intermittent exercise throughout the day) in obese individuals. DESIGN AND METHODS Eleven obese subjects (>30 kg/m(2) ) underwent three 12-h study days: control condition [sedentary behavior (SED)], continuous exercise condition [(EX) 1-h exercise], and intermittent exercise condi...
