5 Year Expression and Neutrophil Defect Repair after Gene Therapy in Alpha-1 Antitrypsin Deficiency.
Alpha-1 antitrypsin deficiency is a monogenic disorder resulting in emphysema due principally to the unopposed effects of neutrophil elastase. We previously reported achieving plasma wild-type alpha-1 antitrypsin concentrations at 2.5%-3.8% of the purported therapeutic level at 1 year after a single intramuscular administration of recombinant adeno-associated virus serotype 1 alpha-1 antitrypsi...
Alpha(1)-antitrypsin is a 45-kDa (394-residue) serine protease inhibitor synthesized by hepatocytes, which is released into the circulatory system and protects the lung from the actions of neutrophil elastase via a conformational transition within a dynamic inhibitory mechanism. Relatively common point mutations subvert this transition, causing polymerisation of α(1)-antitrypsin and deficiency ...
Most patients with alpha1 antitrypsin deficiency do not receive this diagnosis until developing severe complications, in particular when respiratory symptoms are absent. This is a reason for making alpha1 antitrypsin deficiency a possible diagnosis among patients with cryptogenic cirrhosis or other conditions of liver disease without a clear etiology. In this report, a case of cryptogenic cirrh...
Background Alpha-1 antitrypsin deficiency (AATD) is a hereditary disorder defined by low plasma levels of alpha-1 antitrypsin (AAT). It is linked primarily with the development of lung, liver and skin disease. The most common abnormal variant of AAT is the ‘Z’ variant. It is the AATD type most associated with the development of liver disease. The aim of this project is to determine the prevalen...
Chronic obstructive pulmonary disease (COPD) affects over 65 million individuals worldwide, where α-1-antitrypsin deficiency is a major genetic cause of the disease. The α-1-antitrypsin gene, SERPINA1, expresses an exceptional number of mRNA isoforms generated entirely by alternative splicing in the 5'-untranslated region (5'-UTR). Although all SERPINA1 mRNAs encode exactly the same protein, ex...

Emphysema is a chronic progressive lung disease characterised by abnormal permanent enlargement of airspaces as a result of destruction of alveolar walls. Most patients develop emphysema as a consequence of smoking but 1–2% of patients with emphysema develop the condition as a result of a genetic deficiency of the plasma proteinase inhibitor á1-antitrypsin. The two common deficiency variants of...
