Anti-beta 2 glycoprotein I antibodies in centenarians [PDF]
Non-organ-specific autoantibodies are present in centenarians without evidence of autoimmune diseases but conflicting or no data on anti-phospholipid and anti-phospholipid binding proteins were reported.To investigate the presence and antigen specificity of anti-phospholipid and anti-phospholipid binding proteins in centenarians.Seventy-seven ...

Dimers of β2-Glycoprotein I Mimic thein Vitro Effects of β2-Glycoprotein I-Anti-β2-glycoprotein I Antibody Complexes [PDF]
Anti-beta(2)-glycoprotein I antibodies are thought to cause lupus anticoagulant activity by forming bivalent complexes with beta(2)-glycoprotein I (beta(2)GPI). To test this hypothesis, chimeric fusion proteins were constructed of the dimerization domain (apple 4) of factor XI and beta(2)GPI.

Thrombosis and antiphospholipid antibodies in Japanese COVID-19: based on propensity score matching
BackgroundThrombosis is a unique complication of coronavirus disease 2019 (COVID-19). Although antiphospholipid antibodies (aPL) are detected in COVID-19 patients, their clinical significance remains elusive.

Morphology, biophysical properties and protein-mediated fusion of archaeosomes. [PDF]
As variance from standard phospholipids of eubacteria and eukaryotes, archaebacterial diether phospholipids contain branched alcohol chains (phytanol) linked to glycerol exclusively with ether bonds.

Anticardiolipin and anti-beta-2-glycoprotein I antibodies
The anticardiolipin (aCL) antibody test was first established in 1983, using cardiolipin (negatively charged phospholipid) as an antigen in a solid-phase immunoassAy. It was first applied to the study of systemic lupus erythematosus patients, and was found associated with thromboses and recurrent pregnancy losses.

beta 2-Glycoprotein I and anti-beta 2-glycoprotein I antibodies: where are we now? [PDF]
beta 2-Glycoprotein I (beta 2-GPI), a plasma protein with in vitro anticoagulant properties, has been recognized to have an important role in the antiphospholipid syndrome (APS) as a cofactor and an (co)antigen in ELISA assays. Although beta 2-GPI levels were found to be increased in some patients with APS, the clinical value of measuring beta 2-GPI ...

Prevalence of beta 2-glycoprotein I antibody in systemic lupus erythematosus patients with beta 2-glycoprotein I dependent antiphospholipid antibodies. [PDF]
To investigate whether beta 2-glycoprotein I antibody (aGPI) exists in sera that are positive for antiphospholipid antibodies (aPL).Thirty six patients with systemic lupus erythematosus (SLE) and 20 healthy volunteers were recruited. GPI independent and dependent aPL (anticardiolipin (aCL), antiphosphatidylserine, antiphosphatidylinositol ...

In vivo modulation of angiogenesis by beta 2 glycoprotein I [PDF]
Beta 2 glycoprotein I (β2GPI) is the major auto antigen in the antiphospholipid syndrome but also interacts with fibrinolytic and angiogenic proteins. The aim of this study was to examine the angiogenic potential of β2GPI in vivo in β2GPI deficient mice utilizing angiogenic assays. β2GPI deficient mice show increased microvessel formation in comparison

Antiphospholipid Antibodies and Antiphospholipid Syndrome During Pregnancy: Diagnostic Concepts
Antiphospholipid syndrome comprises of a wide spectrum of clinical and obstetric manifestations linked to the presence of antiphospholipid antibodies. APS was described in the context of lupus and later as an isolated syndrome or primary APS.
