Ghrelin Gene Products in Acute and Chronic Inflammation

Ghrelin gene products-the peptides ghrelin, unacylated ghrelin, and obestatin-have several actions on the immune system, opening new perspectives within neuroendocrinology, metabolism and inflammation. The aim of this review is to summarize the available evidence regarding the less known role of these peptides in the machinery of inflammation and autoimmunity, outlining some of their most promising therapeutic applications.
