The anorexigenic leptin and orexigenic ghrelin, are peripheral signals that control appetite via the hypothalamic neuropeptide Y (NPY) system. Ghrelin exists in an inactive (des-acyl) and active (octanoylated) form which acts via the GHS-R1a. Whilst a great deal is understood about central interaction of these peptides their peripheral pathways remain uncertain. Adipose tissue (AT) produces several neuropeptides. Due to the importance of AT in the control of energy homeostasis...
