PROINFLAMMATORY CYTOKINE PROFILE IN PATIENTS WITH DIFFERENT ALPHA-1-ANTITRYPSIN PHENOTYPES

Alpha-1-antitrypsin (A1AT) exerts a wide spectrum of protective effects, being focused on reduction of secondary injury in inflammation. Moreover, A1AT inhibits some serine proteases, and down-regulates production of proinflammatory cytokines. A number of known A1AT phenotypes is accompanied by affe...
