alpha-1-Antitrypsin Information for Pathologists
Acute phase plasma protein predominantly derived from liver which inhibits neutrophil elastase. Most abundant circulating serine protease inhibitor. Elastase digests lung tissue and is secreted by neutrophils during inflammation (Wikipedia). Member of serpin superfamily; homologous to alpha-1-antichymotrypsin. Clinical features
Notable Clinical Features:
Common genetic deficiency, see Liver nontumor chapter. Occurs in 1 per 2,500-5,000 newborns in Western Europe / USA. Incidence is highly dependent on Scandinavian descent within the population. Disorder due to folding errors (IUBMB Life 2009;61:1). Causes emphysema (Orphanet J Rare Dis 2008;3:16), chronic hepatitis (Hum Pathol 2012;43:753) or cirrhosis (Am J Gastroenterol 2008;103:2136, Clin Gastroenterol Hepatol 2012;10:575).
Common Uses By Pathologists:
Immunohistochemistry marker of alpha-1-antitrypsin genetic disease in hepatocytes. Also marker of normal histiocytes and hepatocytes.
