Recent evidence suggests that platelet-associated glycoprotein-specific (GP) antibodies represent true positive autoantibodies and can therefore be taken as the gold standard. Earlier tests, which aimed at detecting platelet-associated IgG (PA-IgG), might have been hampered, e.g. by the variation of platelet size in thrombocytopenic patients. In this study, 206 samples with increased PA-IgG fro...

In severe COVID-19 patients the blood level of autoantibodies (IgG) to neurospecific proteins was determined. It defined marked increase in peripheral myelin protein, protein lipid S100 type 2 dopamine receptors and dopamine. At same time, it designate relationship between levels NMDA receptors. High specific IgG SARS-CoV-2 S-Trimer Protein coincided with high

Some investigatoes reported  taht there is a relationship between.H.pylori chronic infection and the prevalence of acute coronary artery disease(CAD).it is suggested that H.pylori chronic infection causes some changes in serum levels of lipids an lipoproteins and produces inflamatory proteins which could give rise to thrombogenesis.in order to comfirm any correlation between positive history of...

This study was performed to characterize the humoral immune responses with isotype profiles in Mycobacterium tuberculosis infection. PPD-Specific IgG and IgG subclasses were measured using ELISA in 212 patients with pulmonary tuberculosis. The values of PPD-specific IgG were significantly higher in pulmonary tuberculosis patients than those in the control group, and were correlated to the sever...
