Alpha-1-AntitrypsinA mother had a child with cirrhosis of the liver and alpha-1-antitrypsin deficiency. In a subsequent pregnancy the fetal phenotype Pi MZ was detected by isoelectrofocussing in the amniotic fluid. Quantitative assay of alpha-1-antitrypsin gave results in the normal range. ...
Alpha 1-antitrypsin is also referred to as alpha-1 proteinase inhibitor (A1PI) because it inhibits a wide variety of proteases. It protects tissues from enzymes of inflammatory cells, especially neutrophil elastase, and has a reference range in blood of 1.5-3.5 gram/liter (in US the reference...
The study first concluded that induced diarrhea can cause an increase in alpha 1-antitrypsin clearance; if this is not considered in establishing normal values, there may be an overdiagnosis of excess protein leakage in patients with diarrhea. Second, there is a highly significant statistical ...
Alpha1-antitrypsin (α1AT) is an abundant serine-protease inhibitor in circulation. It has an important role in neutralizing the neutrophil elastase activity. Different pathogenic point mutations like Z(E342K)-α1AT have been implicated in the devel
Implications of the three-dimensional structure of alpha 1-antitrypsin for structure and function of serpins.

Intervertebral disc degeneration is a complex disease with high prevalence. It suggests that cell death, senescence, and extracellular matrix degradation are involved in the pathogenesis. Alpha-1 antitrypsin (AAT), a serine protease inhibitor, was previo

The normal plasma level of α1-antitrypsin is 150 to 350 mg/dL. Levels under 80 mg/dL are insufficient to protect the lung from developing emphysema. Most patients under this threshold will have the PiZZ phenotype. These patients can be managed with augmentation therapy, which involves weekly ...

suggesting a relevant role of the serpin in vivo. In normal individuals, α1AT levels range between 10–40 µM in alveolar interstitial fluid, and 2–5 µM in alveolar extracellular lining fluid28,29,30. Assuming that α1AT concentrations further increase during the acute phase respons...
