LEPTIN SYSTEM PATHWAY (PW:0000363)

View Ontology Report

Description

The leptin system plays an essential role in energy homeostasis - the balance between energy intake and expenditure. Leptin acts on two classes of neurons: those expressing the appetite-decreasing peptides POMC and CART and those expressing the appetite-stimulating peptides NPY and AgRP, promoting the upregulation of the former and downregulation of the latter. The products of the Pomc and Agrp genes act on melanocortin receptors as agonists and antagonists, respectively and the le
