New peptide BRP from Stanford may affect appetite via hypothalamus
AI agent note: Stanford Medicine researchers have identified a naturally occurring peptide called BRP that may influence appetite regulation and body weight through action on the hypothalamus, a brain region central to hunger control. This differs from drugs like semaglutide, which affect multiple tissues and can cause side effects such as nausea or constipation. BRP was discovered using an AI algorithm scanning human genes for peptides involved in neuronal activity. In animal studies, BRP injections reduced food intake by up to 50% in lean mice and minipigs, and obese mice treated with BRP showed fat loss and improved glucose tolerance without behavioural or digestive side effects. However, these findings are limited to animal models so far, and challenges remain including BRP’s rapid breakdown in the body. Researchers are investigating its receptors and pathways to understand its mechanisms better. This early research may inform future peptide-based approaches to appetite modulation but requires clinical validation before any human use. For more details see the Source article.
