The disulfide-bonded loop of chromogranin B mediates membrane binding and directs sorting from the trans-Golgi network to secretory granules. (1/1525)

The disulfide-bonded loop of chromogranin B (CgB), a regulated secretory protein with widespread distribution in neuroendocrine cells, is known to be essential for the sorting of CgB from the trans-Golgi network (TGN) to immature secretory granules. Here we show that this loop, when fused to the constitutively secreted protein alpha1-antitrypsin (AT), is sufficient to direct the fusion protein to secretory granules. Importantly, the sorting efficiency of the AT reporter protein bearing two loops (E2/3-AT-E2/3) is much higher compared with that of AT with a single disulfide-bonded loop. In contrast to endogenous CgB, E2/3-AT-E2/3 does not undergo Ca2+/pH-dependent aggregation in the TGN. Furthermore, the disulfide-bonded loop of CgB mediates membrane binding in the TGN and does so with 5-fold higher efficiency if two loops are present on the reporter protein. The latter finding supports the concept that under physiological conditions, aggregates of CgB are the sorted units of cargo which have multiple loops on their surface leading to high membrane binding and sorting efficiency of CgB in the TGN.  (+info)

Identification of DNA polymorphisms associated with the V type alpha1-antitrypsin gene. (2/1525)

alpha1-Antitrypsin (alpha1-AT) is a highly polymorphic protein. The V allele of alpha1-AT has been shown to be associated with focal glomerulosclerosis (FGS) in Negroid and mixed race South African patients. To identify mutations and polymorphisms in the gene for the V allele of alpha1-AT in five South African patients with FGS nephrotic syndrome DNA sequence analysis and restriction fragment length polymorphisms of the coding exons were carried out. Four of the patients were heterozygous for the BstEII RFLP in exon III [M1(Val213)(Ala213)] and one patient was a M1(Ala213) homozygote. The mutation for the V allele was identified in exon II as Gly-148 (GGG)-->Arg (AGG) and in all patients was associated with a silent mutation at position 158 (AAC-->AAT). The patient who was homozygous for (Ala213) also had a silent mutation at position 256 in exon III (GAT-->GAC) which was not present in any of the other four patients. Although the V allele of alpha1-AT is not associated with severe plasma deficiency, it may be in linkage disequilibrium with other genes on chromosome 14 that predispose to FGS. Furthermore, the associated silent mutation at position 158 and the Ala213 polymorphism are of interest, as these could represent an evolutionary intermediate between the M1(Ala213) and M1(Val213) subtypes.  (+info)

The Pseudomonas aeruginosa secretory product pyocyanin inactivates alpha1 protease inhibitor: implications for the pathogenesis of cystic fibrosis lung disease. (3/1525)

Alpha1 Protease inhibitor (alpha1PI) modulates serine protease activity in the lung. Reactive oxygen species inactivate alpha1PI, and this process has been implicated in the pathogenesis of a variety of forms of lung injury. An imbalance of protease-antiprotease activity is also detected in the airways of patients with cystic fibrosis-associated lung disease who are infected with Pseudomonas aeruginosa. P. aeruginosa secretes pyocyanin, which, through its ability to redox cycle, induces cells to generate reactive oxygen species. We tested the hypothesis that redox cycling of pyocyanin could lead to inactivation of alpha1PI. When alpha1PI was exposed to NADH and pyocyanin, a combination that results in superoxide production, alpha1PI lost its ability to form an inhibitory complex with both porcine pancreatic elastase (PPE) and trypsin. Similarly, addition of pyocyanin to cultures of human airway epithelial cells to which alpha1PI was also added resulted in a loss of the ability of alpha1PI to form a complex with PPE or trypsin. Neither superoxide dismutase, catalase, nor dimethylthiourea nor depletion of the media of O2 to prevent formation of reactive oxygen species blocked pyocyanin-mediated inactivation of alpha1PI. These data raise the possibility that a direct interaction between reduced pyocyanin and alpha1PI is involved in the process. Consistent with this possibility, pretreatment of alpha1PI with the reducing agent beta-mercaptoethanol also inhibited binding of trypsin to alpha1PI. These data suggest that pyocyanin could contribute to lung injury in the P. aeruginosa-infected airway of cystic fibrosis patients by decreasing the ability of alpha1PI to control the local activity of serine proteases.  (+info)

Oligosaccharide modification in the early secretory pathway directs the selection of a misfolded glycoprotein for degradation by the proteasome. (4/1525)

The role of conformation-based quality control in the early secretory pathway is to eliminate misfolded polypeptides and unassembled multimeric protein complexes from the endoplasmic reticulum, ensuring the deployment of only functional molecules to distal sites. The intracellular fate of terminally misfolded human alpha1-antitrypsin was examined in hepatoma cells to identify the functional role of asparagine-linked oligosaccharide modification in the selection of glycoproteins for degradation by the cytosolic proteasome. Proteasomal degradation required physical interaction with the molecular chaperone calnexin. Altered sedimentation of intracellular complexes following treatment with the specific proteasome inhibitor lactacystin, and in combination with mannosidase inhibition, revealed that the removal of mannose from attached oligosaccharides abrogates the release of misfolded alpha1-antitrypsin from calnexin prior to proteasomal degradation. Intracellular turnover was arrested with kifunensine, implicating the participation of endoplasmic reticulum mannosidase I in the disposal process. Accelerated degradation occurred in a mannosidase-independent manner and was arrested by lactacystin, in response to the posttranslational inhibition of glucosidase II, demonstrating that the attenuated removal of glucose from attached oligosaccharides functions as the underlying rate-limiting step in the proteasome-mediated pathway. A model is proposed in which the removal of mannose from multiple attached oligosaccharides directs calnexin in the selection of misfolded alpha1-antitrypsin for degradation by the proteasome.  (+info)

Enhanced tumor growth and invasiveness in vivo by a carboxyl-terminal fragment of alpha1-proteinase inhibitor generated by matrix metalloproteinases: a possible modulatory role in natural killer cytotoxicity. (5/1525)

Matrix metalloproteinases (MMPs) are believed to contribute to the complex process of cancer progression. They also exhibit an alpha1-proteinase inhibitor (alphaPI)-degrading activity generating a carboxyl-terminal fragment of approximately 5 kd (alphaPI-C). This study reports that overexpression of alphaPI-C in S2-020, a cloned subline derived from the human pancreas adenocarcinoma cell line SUIT-2, potentiates the growth capability of the cells in nude mice. After stable transfection of a vector containing a chimeric cDNA encoding a signal peptide sequence of tissue inhibitor of metalloproteinase-1 followed by cDNA for alphaPI-C into S2-020 cells, three clones that stably secrete alphaPI-C were obtained. The ectopic expression of alphaPI-C did not alter in vitro cellular growth. However, subcutaneous injection of the alphaPI-C-secreting clones resulted in tumors that were 1.5 to 3-fold larger than those of control clones with an increased tendency to invasiveness and lymph node metastasis. These effects could be a result of modulation of natural killer (NK) cell-mediated control of tumor growth in nude mice, as the growth advantage of alphaPI-C-secreting clones was not observed in NK-depleted mice, and alphaPI-C-secreting clones showed decreased NK sensitivity in vitro. In addition, production of alphaPI and generation of the cleaved form of alphaPI by MMP were observed in various human tumor cell lines and in a highly metastatic subline of SUIT-2 in vitro. These results provide experimental evidence that the alphaPI-degrading activity of MMPs may play a role in tumor progression not only via the inactivation of alphaPI but also via the generation of alphaPI-C.  (+info)

Cytokines and inflammatory mediators do not indicate acute infection in cystic fibrosis. (6/1525)

Various treatment regimens and difficulties with research design are encountered with cystic fibrosis (CF) because no standard diagnostic criteria exist for defining acute respiratory exacerbations. This study evaluated the role of serial monitoring of concentrations of selected cytokines and inflammatory mediators in serum and sputum as predictors of respiratory exacerbation, as useful outcome measures for CF, and to guide therapy. Interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-alpha), neutrophil elastase-alpha-1-protease inhibitor complex (NE complex), protein, and alpha-1-protease inhibitor (alpha-1-PI) were measured in serum and sputum collected from CF patients during respiratory exacerbations and periods of well-being. Levels of NE complex, protein, and alpha-1-PI in sputum rose during respiratory exacerbations and fell after institution of antibiotic therapy (P = 0.078, 0.001, and 0.002, respectively). Mean (+/- standard error of the mean) levels of IL-8 and TNF-alpha were extremely high in sputum (13,780 +/- 916 and 249.4 +/- 23.5 ng/liter, respectively) but did not change significantly with clinical deterioration of the patient (P > 0.23). IL-8 and TNF-alpha were generally undetectable in serum, and therefore these measures were unhelpful. Drop in forced expiratory volume in 1 s was the only clinical or laboratory parameter that was close to being a determinant of respiratory exacerbation (P = 0.055). This study provides evidence of intense immunological activity occurring continually within the lungs of adult CF patients. Measurement of cytokines and inflammatory mediators in CF sputum is not helpful for identifying acute respiratory exacerbations.  (+info)

Probing the unfolding pathway of alpha1-antitrypsin. (7/1525)

Protein misfolding plays a role in the pathogenesis of many diseases. alpha1-Antitrypsin misfolding leads to the accumulation of long chain polymers within the hepatocyte, reducing its plasma concentration and predisposing the patient to emphysema and liver disease. In order to understand the misfolding process, it is necessary to examine the folding of alpha1-antitrypsin through the different structures involved in this process. In this study we have used a novel technique in which unique cysteine residues were introduced at various positions into alpha1-antitrypsin and fluorescently labeled with N, N'-dimethyl-N-(iodoacetyl)-N'-(7-nitrobenz-2-oxa-1, 3-diazol-4-yl)ethylenediamine. The fluorescence properties of each protein were studied in the native state and as a function of guanidine hydrochloride-mediated unfolding. The studies found that alpha1-antitrypsin unfolded through a series of intermediate structures. From the position of the fluorescence probes, the fluorescence quenching data, and the molecular modeling, we show that unfolding of alpha1-antitrypsin occurs via disruption of the A and C beta-sheets followed by the B beta-sheet. The implications of these data on both alpha1-antitrypsin function and polymerization are discussed.  (+info)

A kinetic mechanism for the polymerization of alpha1-antitrypsin. (8/1525)

The mutation in the Z deficiency variant of alpha1-antitrypsin perturbs the structure of the protein to allow a unique intermolecular linkage. These loop-sheet polymers are retained within the endoplasmic reticulum of hepatocytes to form inclusions that are associated with neonatal hepatitis, juvenile cirrhosis, and hepatocellular carcinoma. The process of polymer formation has been investigated here by intrinsic tryptophan fluorescence, fluorescence polarization, circular dichroic spectra and extrinsic fluorescence with 8-anilino-1-naphthalenesulfonic acid and tetramethylrhodamine-5-iodoacetamide. These biophysical techniques have demonstrated that alpha1-antitrypsin polymerization is a two-stage process and have allowed the calculation of rates for both of these steps. The initial fast phase is unimolecular and likely to represent temperature-induced protein unfolding, while the slow phase is bimolecular and associated with loop-sheet interaction and polymer formation. The naturally occurring Z, S, and I variants and recombinant site-directed reactive loop and shutter domain mutants of alpha1-antitrypsin were used to demonstrate the close association between protein stability and rate of alpha1-antitrypsin polymerization. Taken together, these data allow us to propose a kinetic mechanism for alpha1-antitrypsin polymer formation that involves the generation of an unstable intermediate, which can form polymers or generate latent protein.  (+info)

Alpha-1-antitrypsin or α1-antitrypsin (A1AT, A1A, or AAT) is a protein belonging to the serpin superfamily. It is encoded in humans by the SERPINA1 gene. A protease inhibitor, it is also known as alpha1-proteinase inhibitor (A1PI) or alpha1-antiproteinase (A1AP) because it inhibits various proteases (not just trypsin). In older biomedical literature it was sometimes called serum trypsin inhibitor (STI, dated terminology), because its capability as a trypsin inhibitor was a salient feature of its early study. As a type of enzyme inhibitor, it protects tissues from enzymes of inflammatory cells, especially neutrophil elastase, and has a reference range in blood of 0.9-2.3 g/L (in the US the reference range is expressed as mg/dL or micromoles), but the concentration can rise manyfold upon acute inflammation. When the blood contains inadequate amounts of A1AT or functionally defective A1AT (such as in alpha-1 antitrypsin deficiency), neutrophil elastase is excessively free to break down elastin, ...

In addition to its anti-proteinase activity, A1PI showed to have anti-inflammatory, anti-apoptotic and immunomodulatory properties (1-4).. GLASSIA is an injection solution prepared from human plasma collected from healthy volunteer blood donors in accordance with Food and Drug Administration (FDA) and European Medicines Agency (EMA) regulations. GLASSIA was approved in the United States (US) in July 2010 and is indicated for chronic augmentation and maintenance therapy in adults with clinically evident emphysema due to severe hereditary deficiency of Alpha1-PI (alpha1-antitrypsin deficiency). ...
In the present study, we evaluated the impact of the two most relevant AAT variants in two large and well-characterised cohorts of biopsy-proven NAFLD (both cohorts: n=1184) and chronic alcohol misuse (both cohorts: n=2462). We unambiguously found that the Pi*Z variant is a major risk factor for cirrhosis in the context of chronic metabolic injury such as NAFLD and chronic alcohol misuse. These findings are in line with previously published, smaller studies or studies pointing to an association with end-stage liver disease or cryptogenic cirrhosis in general.12 14 15 17 18 21 22 24 25 36 These findings provide a definitive answer and end the controversy about the clinical relevance of heterozygous carriage of the Pi*Z variant in NAFLD and ALD (online supplementary table 1). Moreover, this study is the first report that has systematically investigated the role of the Pi*S variant providing evidence that this variant does not pose a major risk to develop alcoholic or NAFLD-associated cirrhosis. ...

Alpha1-antitrypsin molecule. Computer model showing the structure of alpha1-antitrypsin (blue-green) with its reactive loop (pink). This protein, also known as alpha-1 proteinase inhibitor, is a type of serine protease inhibitor (serpin) and is named after its ability to covalently bind and irreversibly inactivate serine proteases, including the digestive enzyme trypsin. It plays a key role in mediating inflammation and a deficiency results in the lung disease emphysema. - Stock Image C035/5538
A protease/anti-protease imbalance is a characteristic feature of inflammatory lung diseases such as cystic fibrosis (CF) and COPD. However, alpha-1-antitrypsin (AAT) enzyme replace- ment therapy (ERT) trials have not shown conclusive evidence of therapeutic benefit. Here, we assessed whether transduction of murine lungs with a pseudotyped SIV vector, rSIV.F/HN-hCEF-AAT, generates therapeutic levels of AAT. Mice were transduced with rSIV.F/HN-hCEF-AAT (1.4e8 TU/mouse) by nasal instillation and culled 10 days post-trans- duction. AAT levels in lung homogenate and epithelial lining fluid (ELF) were 3 logs above controls (p | 0.05), and hAAT concentration in ELF was 92-28lg/ml, similar to the thera- peutic AAT level in ELF of 70lg/ml. For comparison trans- fection of mouse lung with cationic lipid GL67A complexed to hCEFI-AAT only led to 0.4-0.1lg/ml AAT in ELF. A neutrophil elastase (NE) activity assay showed that the recombinant AAT successfully neutralised NE activity (p | 0.05). In a separate

The AAT gene contains at least two enhancer elements , one at the 5 end of the gene and the other at the 3 end. The 5 enhancer is dominant under basal conditions and, following stimulation with IL-6 and related cytokines, both enhancers are essential and the 3 enhancer plays a major role.. Interferon γ and transforming growth factor β also modulate the hepatocyte response to IL-6. In addition to cytokines having an effect on AAT gene regulation, dexamethasone and oestrogen may have a stimulatory effect on gene regulation.. Monocyte AAT production appears to be primarily under the control of IL-6, although lipopolysaccharide , interleukin-1β (IL-1β) and tumour necrosis factor α (TNFα) all cause a 2±3-fold increase in AAT production by peripheral blood monocytes.. ...

Background Alpha-1 antitrypsin deficiency is an inherited disorder that can cause lung disease (chronic obstructive pulmonary disease or COPD, which is a chronic lung condition that prevents the air supply from getting to the lungs). It affects about 1 in 1600 to 1 in 5000 people. Patients with lung disease suffer from shortness of breath, reduced ability to exercise and wheezing. People who smoke are more seriously affected and have a greater risk of dying from the disease.. Study characteristics We reviewed the benefits and harms of treating patients who have the form of the disease that affects the lungs with alpha-1 antitrypsin extracted from blood donations. We found three randomised clinical trials (283 participants in the analyses) comparing treatment with alpha-1 antitrypsin with placebo (a pretend treatment) for two to three years. All participants were ex-smokers or had never smoked but had the genetic problem that carried a high risk of developing lung problems. The evidence is ...

PY - 1990/8/16. Y1 - 1990/8/16. N2 - Molecular analysis of α1-antitrypsin (α1AT) Wbethesda revealed that it differs from the normal M1(A1a213) allele by a single base mutation causing an amino acid substitution A1a336GCT → Thr ACT. Evaluation of α1AT biosynthesis directed by the Wbethesda allele showed that although Wbethesda α1AT mRNA was translated normally invitro, transfection of the Wbethesda cDNA into COS-I cells was associated with human α1AT secretion of 50% that of cells transfected with a normal α1AT cDNA. The pattern of α1AT biosynthesis was not intracellular accumulation as observed with the common Z α1AT deficiency allele, but reduced intracellular α1AT, suggesting intracellular degradation of the newly synthesized Wbethesda molecule. Together these observations suggest that in ...

Alpha-1 antitrypsin is the main inhibitor of neutrophil elastase in the lung. Although it is principally synthesized by hepatocytes, alpha-1 antitrypsin is also secreted by bronchial epithelial cells. Gene mutations can lead to alpha-1 antitrypsin deficiency, with the Z variant being the most clinically relevant due to its propensity to polymerize. The ability of bronchial epithelial cells to produce Z-variant protein and its polymers is unknown. We investigated the expression, accumulation, and secretion of Z-alpha-1 antitrypsin and its polymers in cultures of transfected cells and in cells originating from alpha-1 antitrypsin-deficient patients. Experiments using a conformation-specific antibody were carried out on M- and Z-variant-transfected 16HBE cells and on bronchial biopsies and ex vivo bronchial epithelial cells from Z and M homozygous patients. In addition, the effect of an inflammatory stimulus on Z-variant polymer formation, elicited by Oncostatin M, was investigated. Comparisons of groups
New life-saving treatments for Alpha 1-antitrypsin deficiency in clinical trial on The Impact of Delayed Diagnosis of Alpha-1 Antitrypsin Deficiency
Introduction Alpha-1 antitrypsin deficiency (AATD) is a hereditary disorder affecting about 1 in 3000 people in the UK commonly associated with early-onset emphysema. There are two common deficiency alleles - PiS and PiZ. PiZZ patients have severe AATD, with levels of 10-15% normal. PiSZ patients have less severe deficiency (≈ 40% normal) and are generally thought to have a minimal risk. We hypothesised that if PiSZ patients were at lower risk of COPD than PiZZ, and their lung disease would be more characteristic of usual COPD than that of PiZZ patients.. ...

phdthesis{a13a8c55-510f-4fb9-a532-a58534436a33, abstract = {Alpha-1-antitrypsin (AAT) is a glycoprotein synthesised in the liver. Its main role is to protect lung tissue from destruction by neutrophil elastase. In severe (PiZZ) AAT deficiency, there is an increased risk of emphysema, especially in smokers. The deficiency is caused by the retention and aggregation by polymerization of the AAT molecules in the liver, which increases the risk of neonatal cholestasis in infancy, and cirrhosis and hepatocellular carcinoma in adulthood. To investigate the prevalence of severe and moderate (PiSZ) AAT deficiency and follow its natural course, all 200,000 Swedish new-born children were screened in 1972-74.

Please refer to the alpha 1-antitrypsin for the various protease inhibitor (Pi) genotypes and phenotypes. Normally, alpha 1-antitrypsin is produced in the liver and exists in levels of 1.5-3.5 gram/litre. When the levels are reduced (40-60%, in the PiSS, PiMZ and PiSZ phenotypes), most people will only suffer symptoms if they smoke, as the levels are still sufficient to counteract normal elastase activity in inflammation. Only in the PiZZ phenotype, when the levels are less than 15%, emphysema develops at a young age, and 50% will develop liver cirrhosis due to the accumulated protein, which is not secreted properly. On liver biopsy, they show as PAS-positive, diastase-negative granules. Apart from increasing the inflammatory reaction in the airways, cigarette smoke also directly inactivates alpha 1-antitrypsin by oxidizing essential methionine residues to sulfoxide forms, decreasing the enzyme activity by a rate of 2000. ...

Alpha-1 antitrypsin deficiency (AATD) is a common, potentially lethal inborn disorder caused by mutations in alpha-1 antitrypsin (AAT). Homozygosity for the Pi*Z variant of AAT (Pi*ZZ genotype) causes lung and liver disease, whereas heterozygous Pi*Z carriage (Pi*MZ genotype) predisposes to gallstones and liver fibrosis. The clinical significance of the more common Pi*S variant remains largely undefined and no robust data exist on the prevalence of liver tumours in AATD.Baseline phenotypes of AATD individuals and non-carriers were analysed in 482 380 participants in the UK Biobank. 1104 participants of a multinational cohort (586 Pi*ZZ, 239 Pi*SZ, 279 non-carriers) underwent a comprehensive clinical assessment. Associations were adjusted for age, sex, body mass index, diabetes and alcohol consumption.Among UK Biobank participants, Pi*ZZ individuals displayed the highest liver enzyme values, the highest occurrence of liver fibrosis/cirrhosis (adjusted OR (aOR)=21.7 (8.8-53.7)) and primary ...
Alpha 1-antitrypsin deficiency is a genetic disorder caused by defective production of alpha 1-antitrypsin (AAT). Gene therapy approaches have been conducted in patients with AAT deficiency with successful AAT expression, but not to the therapeutic levels required to reduce the risk of emphysema. Codon optimization, a somewhat new and evolving technique, is used by many scientists to maximize protein expression in living organisms by altering translational and transcriptional efficiency as well as protein refolding. The purpose of this study was to develop single stranded and double stranded AAT gene constructs, test their protein expression in vitro, and compare with those levels expressed by the AAT construct that is currently in clinical trials. Three constructs were to be developed, yet only one construct was successfully cloned. This clone, optimized ds-CB-AAT, illustrated increased AAT protein expression as the transfection time increased. However, protein levels were appreciably lower in

The hereditary disorder alpha-1 antitrypsin (AAT) deficiency results from mutations in the SERPINA1 gene and presents with emphysema in young adults and liver disease in childhood. The most common form of AAT deficiency occurs because of the Z mutation, causing the protein to fold aberrantly and accumulate in the endoplasmic reticulum (ER). This leads to ER stress and contributes significantly to the liver disease associated with the condition. In addition to hepatocytes, AAT is also synthesized by monocytes, neutrophils, and epithelial cells. In this study we show for the first time that the unfolded protein response (UPR) is activated in quiescent monocytes from ZZ individuals. Activating transcription factor 4, X-box binding protein 1, and a subset of genes involved in the UPR are increased in monocytes from ZZ compared with MM individuals. This contributes to an inflammatory phenotype with ZZ monocytes exhibiting enhanced cytokine production and activation of the NF-kappaB pathway when ...
Alpha 1-antitrypsin deficiency is an inherited disorder that can cause lung disease in adults and liver disease in adults and children. Alpha-1 antitrypsin (AAT) is a protein that protects the lungs. The liver usually makes the protein, and releases it into the bloodstream. Because of a mutation in the SERPINA1 gene, some people have little or no AAT. Not having enough AAT may lead to emphysema or liver problems. Smoking increases the risk. A deficiency of AAT can be treated but not cured. One treatment involves adding to or replacing the missing protein. More severe cases may require a lung transplant. This condition is caused by mutations in the SERPINA1 gene and inherited in an autosomal co-dominant fashion ...
The AATD is a metabolic disorder that predisposes the affected individual to chronic pulmonary disease, in addition to chronic liver disease, cirrhosis, and hepatocellular carcinoma. Clinical manifestations are always present in patients with complete absence of serum alpha-1 antitrypsin (null variants). The majority of patients with ZZ or SZ genotypes, and some others with the SS genotype, have pulmonary or hepatic symptoms. Severe lung and liver disease are rarely observed in the same person. Heterozygous individuals, with both a normal and a variant allele (MZ or MS), rarely develop clinical symptoms. In most patients with symptomatic AATD, the dominant manifestation is lung disease: the symptoms appear earlier and may proceed faster if additional risk factors are present, like smoke or air pollutants. The mean life expectancy of homozygous patients (ZZ and SS variant) is from 48 to 52 years for smokers and from 60 to 68 years for nonsmokers. Severe pulmonary impairment, manifesting as COPD ...

A1AT deficiency remains undiagnosed in many patients. Patients are usually labeled as having COPD without an underlying cause. It is estimated that about 1% of all COPD patients actually have an A1AT deficiency. Testing is recommended in those with COPD, unexplained liver disease, unexplained bronchiectasis, granulomatosis with polyangiitis or necrotizing panniculitis.[10] American guidelines recommend that all people with COPD are tested,[10] whereas British guidelines recommend this only in people who develop COPD at a young age with a limited smoking history or with a family history.[14] The initial test performed is serum A1AT level. A low level of A1AT confirms the diagnosis and further assessment with A1AT protein phenotyping and A1AT genotyping should be carried out subsequently.[15] As protein electrophoresis does not completely distinguish between A1AT and other minor proteins at the alpha-1 position (agarose gel), antitrypsin can be more directly and specifically measured using a ...

Eighty seven PiZZ, 32 PiSZ, and 92 control subjects (PiMM) answered a questionnaire on medication and alcohol consumption and provided blood samples. Liver stiffness was assessed by ...
UNLABELLED: Alpha-1-antitrypsin deficiency [AATD] is associated with variable development of emphysema and other features of chronic obstructive pulmonary disease [COPD]. Matrix metalloproteinases [MMPs] are believed to be important in the pathophysiology of COPD, and may therefore confer susceptibility to this phenotype in patients with AATD. OBJECTIVES: to assess the role of polymorphism of MMP1, MMP3 and MMP12 in AATD phenotypes. METHODS: 424 PiZZ subjects from the UK AATD Registry were assessed for history of chronic bronchitis [CB], post-bronchodilator lung function impairment and decline of lung function. Tag single nucleotide polymorphisms (SNPs) for MMP1, MMP3 and MMP12 were chosen using HapMap [r(2)|0.8, MAF|0.05] and were genotyped using TaqMan genotyping technologies. Quantitative genetic association was assessed using regression modelling to correct for covariates. RESULTS: in patients with AATD, carriers of the G allele of rs678815 [MMP3] had lower gas transfer [KCO] [P = 0.025, B =-7.766]
article{8610527, abstract = {Despite recent improvements, α1-antitrypsin deficiency (AATD) remains a rarely diagnosed and treated condition. To assess the variability of AATD diagnosis/treatment in Europe, and to evaluate clinicians views on methods to optimise management, specialist AATD clinicians were invited to complete a web-based survey. Surveys were completed by 15 physicians from 14 centres in 13 European countries. All respondents perceived the AATD diagnosis rate to be low in their country; 77% of physicians believed that ∼15% of cases were diagnosed. Low awareness was perceived as the greatest barrier to diagnosis. Spirometry was considered more practical than quantitative computed tomography (QCT) for monitoring AATD patients in clinical practice; QCT was considered more useful in trials. AAT therapy provision was reported to be highly variable: France and Germany were reported to treat the highest proportion (∼60%) of diagnosed patients, in contrast to the UK and Hungary, ...
Lung cancer development is a multifaceted process involving environmental and genetic factors, but their intricate interaction and extent of predisposition remains ill-defined. This study investigated the role of alpha1-antitrypsin deficiency (α1ATD), chronic obstructive pulmonary disease (COPD) and tobacco smoke exposure in lung cancer development in 1856 patients with lung cancer. The two control groups were free of any cancer and comprised 1585 community residents and 902 full siblings of patients. The α1AT alleles were tested in 1443 patients, 797 unrelated controls and 902 full siblings. The carrier rate was 13.4%, 7.8% and 9.9%, respectively.. The findings suggest that α1ATD carriers are at a 70-100% increased risk of lung cancer, particularly adenocarcinoma and squamous cell subtypes (adjusted for the effects of tobacco smoke exposure and COPD). Depending on smoking intensity, smokers were noted to have a 2-9-fold higher risk of lung cancer than never smokers. The study also confirmed ...
TY - JOUR. T1 - Lung disease associated with α1-antitrypsin deficiency. AU - Tuder, Rubin M.. AU - Janciauskiene, Sabina M.. AU - Petrache, Irina. PY - 2010/11. Y1 - 2010/11. N2 - α1-Antitrypsin (A1AT) is a polyvalent, acute-phase reactant with an extensive range of biological functions that go beyond those usually linked to its antiprotease (serpin) activities. Genetic mutations cause a systemic deficiency of A1AT, leading to liver and pulmonary diseases, including emphysema and chronic bronchitis. The pathogenesis of emphysema, which involves the destruction of small airway structures and alveolar units, is triggered by cigarette smoke and pollutants. The tissue damage caused by these agents is further potentiated by the mutual interactions between apoptosis, oxidative stress, and protease/antiprotease imbalance. These processes lead to the activation ofendogenous mediators of tissue destruction, including the lipid ceramide, extracellular matrix proteins, and abnormal inflammatory cell ...
A1AT is caused by mutations in the SERPINA1 gene that is responsible for production of the alpha-1 antitrypsin protein. Normally, this protein is produced in the liver and released in the blood and functions to protect the body from the neutrophil elastase enzyme. A1AT also appears to have anti-inflammatory effects independent of its anti-neutrophil elastase activity. Mutations in the SERPINA1 gene result in production of an abnormal protein that gets trapped in the liver, resulting in low serum levels of A1AT that can predispose to lung breakdown by neutrophil elastase and other proteolytic enzymes (enzymes that break down proteins). In addition, abnormal A1AT protein can accumulate in the liver and cause scarring damage. Over 150 different mutations in the SERPINA1 gene have been identified to date, with the most common termed S and Z, whereas the normal version (allele) of the gene is termed M. The S allele causes serum levels of A1AT to be moderately low and the Z allele is associated with ...
Alpha1-antitrypsin deficiency (AATD) was first described by Laurell and Eriksson in 1963. Laurell noted the absence of the band of alpha1- protein in 5 of 1500 serum protein electrophoreses (SPEP) submitted to his laboratory in Sweden.
Alpha-1 antitrypsin (A1AT) deficiency is a common inherited condition caused by a lack of a protease inhibitor (Pi) normally produced by the liver. The role of A1AT is to protect cells from enzymes such as neutrophil elastase.. ...

The measurement of forced expiratory volume in 1 second (FEV1) and its decline over time are prognostic indicators of early chronic airflow obstruction. Although alpha1-antitrypsin (AAT) deficiency (Z allele) was shown to be a risk factor for rapid decline in lung function, individuals with the same AAT genotype may differ in their phenotypes suggesting the presence of other genetic modifiers.

In Response:. We appreciate the comments raised by Dahl et al in the letter above. However, there are a number of differences in the study design reported in our article published in Arteriosclerosis, Thrombosis, and Vascular Biology1 and that of both Dahl et al2 and Elzouki et al,3 which could have led to discrepancies in the concluded role for alpha-1-antitrypsin (AAT). While our study examined the association of common and rare AAT variants with progression of atherosclerosis in individuals with well defined atherosclerotic disease, the others looked at the occurrence of ischemic heart disease (IHD) or ischemic cerebrovascular disease (ICVD) in individuals who carried rare AAT deficiency genotypes compared with controls. Atherosclerosis progression, IHD, and ICVD are very different disease endpoints, and furthermore, the causes of ischemia are multiple.4 In addition, while our study is a prospective analysis of angiographically defined disease, the other two are case:control analyses. So the ...
