Morphology, biophysical properties and protein-mediated fusion of archaeosomes. [PDF]

PLoS ONE, 2012
As variance from standard phospholipids of eubacteria and eukaryotes, archaebacterial diether phospholipids contain branched alcohol chains (phytanol) linked to glycerol exclusively with ether bonds.

Prevalence of beta 2-glycoprotein I antibody in systemic lupus erythematosus patients with beta 2-glycoprotein I dependent antiphospholipid antibodies. [PDF]

Annals of the Rheumatic Diseases, 1995
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 ...

Antiphospholipid Antibodies and Antiphospholipid Syndrome During Pregnancy: Diagnostic Concepts

Frontiers in Immunology, 2015
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.

Studies on specific interaction of beta-2-glycoprotein I with HBsAg

World Journal of Gastroenterology, 2003
To observe the binding activity of beta-2-glycoprotein I(beta(2)GPI) to hepatitis B surface antigen (HBsAg) and the possible roles of beta(2)GPI in hepatitis B virus (HBV) infection.The rationale of ELISA methods and ELISA-based research method and ligand-blotting technique were used to detect the specific interaction of beta(2)GPI with HBsAg.With the ...

OsVTC1-1 RNAi Mutant with Reduction of Ascorbic Acid Synthesis Alters Cell Wall Sugar Composition and Cell Wall-Associated Proteins

Agronomy, 2022
Ascorbic acid (AsA) or Vitamin C is an antioxidant molecule and plays an important role in many biological processes in plants. GDP-D-mannose pyrophosphorylase (GMP or VTC1) catalyzes the synthesis of GDP-D-mannose, which is a precursor for AsA ...

Differences in Endothelial Activation and Dysfunction Induced by Antiphospholipid Antibodies Among Groups of Patients With Thrombotic, Refractory, and Non-refractory Antiphospholipid Syndrome

Frontiers in Physiology, 2021
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by pregnancy morbidity or thrombosis and persistent antiphospholipid antibodies (aPL) that bind to the endothelium and induce endothelial activation, which is evidenced by the ...

Probable human origin of the SARS-CoV-2 polybasic furin cleavage motif

BMC Genomic Data, 2023
Background The key evolutionary step leading to the pandemic virus was the acquisition of the PRRA furin cleavage motif at the spike glycoprotein S1/S2 junction by a progenitor of SARS-CoV-2.
