Alfa 1-antitripsin ili α1-antitripsin (A1AT) je proteazni inhibitor iz serpinske superfamilije. On je generalno poznat kao serumski tripsinski inhibitor. Alfa 1-antitripsin se takođe naziva alfa-1 proteinazni inhibitor (A1PI), jer inhibira širok opseg proteaza.[1] On štiti tkiva od enzima inflamatornih ćelija, posebno neutrofilne elastaze, i ima referentni opseg u krvi od 1,5 - 3,5 gram/litre, mada koncentracija može da bude znatno viša nakon akutne inflamacije.[2] U njegovom odsustvu, neutrofilna elastaza nesmetano razlaže elastin, koji doprinosi elastičnosti pluća, što stvara respiratorne probleme, kao što je emfisema.
