Low levels of IgG recognizing the alpha-1-antitrypsin (A1AT)
61 The aim of this study was to examine oxidative stress and low level of alpha62 1-antitrypsin (A1AT) in primary Sjögren's syndrome (pSS), and evaluate the 63 associated autoreactivity against unmodified and their 4-hydroxy-2-nonenal (HNE)64 modified peptides with pSS. Two differentially expressed proteins, alpha-1-acid 65 glycoprotein 1 (A1AG1) and A1AT, exhibited 2-fold differences, and thei...
متن کاملActive Trafficking of Alpha 1 Antitrypsin across the Lung Endothelium
The homeostatic lung protective effects of alpha-1 antitrypsin (A1AT) may require the transport of circulating proteinase inhibitor across an intact lung endothelial barrier. We hypothesized that uninjured pulmonary endothelial cells transport A1AT to lung epithelial cells. Purified human A1AT was rapidly taken up by confluent primary rat pulmonary endothelial cell monolayers, was secreted extr...
متن کاملPrevalence of Alpha-1 Antitrypsin (A1AT) Deficiency among Patients with COPD in Kerman, Iran
Background: One of the genetic risk factors for chronic obstructive pulmonary disease (COPD) is deficiency of Alpha-1 Antitrypsin (A1AT). There is no exact statistics about the prevalence of this disease in different regions of Iran. The present study aimed to determine the prevalence of alpha-1 antitrypsin (A1AT) deficiency in COPD patients in Kerman, Iran. Metho...
متن کاملPolymerized alpha-antitrypsin is present on lung vascular endothelium. New insights into the biological significance of alpha-antitrypsin polymerization.
AIMS The damage to lung tissue in chronic obstructive pulmonary disease (COPD) may involve the progressive loss of pulmonary vascular endothelial cells. Endothelial binding of alpha1-antitrypsin (alpha1-AT) derived from plasma has been identified, and alpha1-AT deficiency is a known genetic risk factor associated with alpha1-AT polymerization and COPD development. Therefore, in the present stud...
متن کاملHeritability of lung function in severe alpha-1 antitrypsin deficiency.
Severe alpha-1 antitrypsin (AAT) deficiency is a proven genetic risk factor for COPD, but there is marked variation in the development of COPD among AAT deficient subjects. To investigate familial aggregation of lung function in subjects with AAT deficiency, we estimated heritability for forced expiratory volume in 1 s (FEV1) and FEV1/forced vital capacity (FVC) in 378 AAT deficient subjects fr...
