Современная молекулярно-биологическая концепция исходит из дисбаланса в системе протеолиз–антипротеолиз, альфа1-антитрипсин является основным ингибитором сериновых протеаз, к которым относятся трипсин, химотрипсин, нейтрофильная эластаза, тканевой калликрин, фактор Х «а» и плазминоген. Ген PI (proteinase inhibitor) расположен на длинном плече хромосомы 14 (14q31-32), продуктом данного гена и является гликопротеин альфа1- антитрипсин. В двух типах клеток – макрофагах и гепатоцитах – экспрессируется ген PI, функция их заключается в связывании тканевой специфичности ингибитора.</p></abstract><trans-abstract xml:lang="en"><p>This article reflects the genetic aspects of chronic obstructive pulmonary disease. Modern molecular biology concept comes from an imbalance in the system proteolysis - antiproteoliz , alpha 1- antitrypsin is a major inhibitor of serine proteases, which include trypsin, chymotrypsin, neutrophil elastase, tissue kallikrin, Factor X "a" and plasminogen. The gene PI (proteinase inhibitor) located on the long arm of chromosome 14 (14q31- 32), and the gene product is glycoprotein alpha1 - antitryprisin. Two types of cells expressing the gene PI - macrophages and hepatocytes, the function of hepatocyte, associate tissue specificity of the inhibitor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>хроническая обструктивная болезнь лёгких</kwd><kwd>альфа1-антитрипсин</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chronic obstructive pulmonary disease</kwd><kwd>alpha1 - antitrypsin</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дворецкий Л.И.
