Adipose tissue is not merely a storage depot of triacylglycerols but also a major endocrine organ. Its cells, including adipocytes, synthesize and secrete a range of biologically active molecules termed adipokines. Adipokines that display the properties of cytokines are often called adipocytokines. In recent years there has been increasing interest in a new adipokine called chemerin. Chemerin is a protein synthesized mostly by the adipose tissue and the liver as inactive pre‑pro‑chemerin. After the intracellular hydrolytic cutting off of the 20‑amino‑acid N‑terminal polypeptide, it is secreted into the bloodstream as inactive pro‑chemerin. Biologically active chemerin is then derived from pro‑chemerin after cleavage of the C‑terminal fragment by serum proteases involved in inflammation, coagulation and fibrinolysis. Proteolytic cleavage leads to formation of several chemerin‑derived peptides, both biologically active (often with opposing functions) and inactive. Within the last decade, there has been a growing number of publications regarding the role of chemerin in human disease. It seems to be implicated in the inflammatory response, metabolic syndrome, cardiovascular disease and alimentary tract disorders. The article presents the most recent information on the role of chemerin in human disease, and specifically alimentary tract disorders. The available evidence suggests that chemerin is an important link between adipose tissue mass, metabolic processes, the immune system and inflammation, and therefore plays a major role in human pathophysiology.
