TY - JOUR AU - Stockley, Robert A. PY - 2015 TI - The multiple facets of alpha-1-antitrypsin JF - Annals of Translational Medicine; Vol 3, No 10 (June 26, 2015): Annals of Translational Medicine Y2 - 2015 KW - N2 - Alpha-1-antitrypsin (AAT) is recognised as a potent inhibitor of serine proteinases. Genetic deficiency is associated with several neutrophilic diseases including severe emphysema. This is believed to reflect the loss of inhibition of neutrophilic serine proteinases that then result in local tissue damage (the proteinase/antiprotease hypothesis). In recent years the role of AAT in the control of inflammatory and immunological processes has become identified. Although in some instances this may reflect its ability to control pro-inflammatory effects of serine proteinases it has also become recognised that it has non proteolytic mediated functions. This poly functional role is starting to become recognised offering a possibility of its use as a therapeutic agent in many clinical disease areas. The current review explores both the traditional and non-traditional function of AAT through published literature. UR - https://atm.amegroups.org/article/view/6399
