Alpha 1-acid Glycoprotein (AGP), also known as Orosomucoid, is a Lipocalin family acute-phase protein that is produced by the liver in response to inflammation and infection. Its serum concentration can increase 2-5 fold, making it one of the predominant proteins in serum. AGP functions as a carrier protein for many basic and neutral lipophilic drugs including steroid hormones. It can inhibit neutrophil migration in sepsis, exert a protective effect in severe bacterial infection, and inhibit platelet aggregation. The glycosylation pattern of alpha 1-Acid Glycoprotein influences its anti-inflammatory properties and is associated with various pathophysiological states.
