| pubmed-article:20977581 | pubmed:abstractText | Relaxin is a polypeptide hormone involved in pregnancy and lactation. It is mainly secreted by the corpus luteum and placenta, but is expressed in a number of other tissues, including heart and brain. Within the brain, relaxin is expressed in the olfactory and limbic systems, the cortex and the hypothalamic arcuate nucleus (ARC). Its cognate receptor, relaxin family peptide receptor 1 (RXFP1), is also widely expressed in the brain, including the hypothalamic ARC and paraventricular nucleus (PVN), areas important in appetite regulation. The aim of this study was to investigate whether relaxin influences food intake through central hypothalamic circuits. | lld:pubmed |
