Approximately 50% of all global blindness is caused by cataract in adults aged ≥50 years. The mechanisms the disease are most arguably related to a redox imbalance and inflammation; therefore, aim study was evaluate processes associated with inflammation patients. Twenty-four patients 22–60 years (62.5% females) participated study, 33 controls 28–60 (66.7% females). Venous blood serum subjects ...

BACKGROUND 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...

Alpha 1 antitrypsin deficiency is a hereditary condition characterized by low alpha 1 proteinase inhibitor (also known as alpha 1 antitrypsin [AAT]) serum levels. Reduced levels of AAT allow abnormal degradation of lung tissue, which may ultimately lead to the development of early-onset emphysema. Intravenous infusion of AAT is the only therapeutic option that can be used to maintain levels abo...

Unlike most globular proteins, the native form of serine protease inhibitors (serpins) is strained. Previous studies of human alpha(1)-antitrypsin, a prototype plasma serpin, revealed that various unfavorable interactions, such as overpacking of side chains, buried polar groups and cavities, are the structural basis of the strain. The local strain could be relieved by various stabilizing single...

Using isoelectric focusing (IEF) and radial immunodiffusion (RID) techniques, serum samples from 100 normal healthy adults and 21 patients with pulmonary emphysema were analysed to identify various alpha 1 antitrypsin phenotypes and the serum concentrations. Ten percent of the patients had low serum values. The normal or most common genetic form, MM, is the predominant phenotype in both control...

Forty-two cases of hepatocellular carcinoma (HCC) were examined for the presence of the inclusions of alpha-1-antitrypsin (AAT), which indicate a carrier state for the Pi Z gene. These were found in the non-neoplastic liver tissue of two cases of HCC and in one of the 98 control livers, a difference that is not statistically significant. Typical globules of AAT deficiency were not found in HCC ...

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...
