Peptide yyreceptor The peptide YY hormone function is multifaceted, primarily revolving around its role as a crucial regulator of appetite and energy balance. This gut hormone, released in response to nutrient ingestion, acts as a short-term appetite suppressant, signaling satiety to the brain and thereby limiting food intake. Beyond its well-established role in controlling hunger levels, peptide YY (PYY) also influences various gastrointestinal functions and plays a part in maintaining the health of the gut microbiome.
Peptide YY (PYY) is a peptide hormone produced mainly by L-cells in the small and large intestines作者：JA Cooper·2014·被引用次数：101—Peptide YY (PYY) isan acute satiety signal released upon nutrient ingestionand has been shown to decrease food intake when administered .... Its release is triggered by the presence of nutrients in the digestive tract, particularly fats and carbohydrates. Once released, PYY travels through the bloodstream to the brain, where it interacts with specific receptors, primarily NPY receptors in the hypothalamus. This interaction leads to a reduction in appetite and an increase in feelings of fullness, effectively signaling the end of a meal. This mechanism is vital for regulating food intake and preventing overeating. Studies indicate that PYY levels are often reduced in individuals with obesity, suggesting a potential link between impaired PYY signaling and weight gain.
While appetite regulation is a primary function, PYY's influence extends to other aspects of gastrointestinal physiology. It plays a significant role in slowing down gastric emptying and the transit of food through the small intestine. This slower passage allows for more efficient digestion and absorption of nutrients. Furthermore, PYY has been shown to inhibit gastric and pancreatic secretions, further contributing to the regulated management of food processing. Its actions are crucial for maintaining overall gut function and ensuring proper nutrient uptake.
The connection between peptide YY and metabolic health is an active area of research. Beyond its direct impact on food intake, PYY is involved in the maintenance of fuel homeostasis2025年9月12日—PYY(3-36) is a potent anorexigenic hormone(reduces appetite) 3 · Acts primarily through Y2 receptors in the arcuate nucleus of the hypothalamus .... Emerging research suggests that PYY may also influence glucose metabolism, modulating the secretion of insulin and glucagon. This pleiotropic nature means PYY is not just an appetite regulator but a hormone with broader implications for energy balance and metabolic control. Its potential therapeutic applications, particularly in the context of obesity and type 2 diabetes, are being explored, with synthetic forms like PYY(3-36) showing promise in reducing appetite and aiding weight management.PYY is a short-term appetite regulatorof the neuropeptide Y family, released in proportion to meal energy content and shown to reduce food intake in rodents ...
Recent findings highlight an expanded role for peptide YY, connecting it to the health of the gut microbiome and even immune function. While the exact mechanisms are still being elucidated, PYY's involvement in maintaining the gut environment suggests a broader impact on the body's internal ecosystem. This emerging understanding underscores the complexity of gut hormones and their intricate interplay with systemic health.Peptide YY in Type 2 Diabetes: A Complementary Gut ...
Circulating levels of PYY can be influenced by various factors, including meal composition, the timing of nutrient ingestion, and individual physiological states.Peptide YY (PYY), human | Gut Hormone For instance, the type and amount of macronutrients consumed can affect the magnitude of PYY release3天前—Peptide YY (PYY): a small protein made by intestinal cells thathelps regulate appetite, gut movement and now, it seems, gut sensitivity.
