Anti-phospholipid antibodies are directed against a complex antigen that includes a lipid-binding inhibitor of coagulation: beta 2-glycoprotein I (apolipoprotein H).

Proceedings of the National Academy of Sciences of the United States of America, 1990
Anti-phospholipid (aPL) antibodies that exhibit binding in cardiolipin (CL) ELISA can be purified to greater than 95% purity by sequential phospholipid affinity and ion-exchange chromatography. However, these highly purified aPL antibodies do not bind to

Thrombosis and antiphospholipid antibodies in Japanese COVID-19: based on propensity score matching

Frontiers in Immunology, 2023
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]

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.

Anticardiolipin and anti-beta-2-glycoprotein I antibodies

Autoimmunity, 2005
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.

Dimers of β2-Glycoprotein I Mimic thein Vitro Effects of β2-Glycoprotein I-Anti-β2-glycoprotein I Antibody Complexes [PDF]

Journal of Biological Chemistry, 2001
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.

Noise driven dynamic phase transition in a a one dimensional Ising-like model [PDF]

Phys. Rev E 81 : 032103 (2010), 2009
The dynamical evolution of a recently introduced one dimensional model in \cite{biswas-sen} (henceforth referred to as model I), has been made stochastic by introducing a parameter $\beta$ such that $\beta =0$ corresponds to the Ising model and $\beta \to \infty$ to the original model I. The equilibrium behaviour for any value of $\beta $ is identical:

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.

Critical values for the $β$-transformation with a hole at $0$ [PDF]

arXiv, 2021
Given $\beta\in(1,2]$, let $T_\beta$ be the $\beta$-transformation on the unit circle $[0,1)$ such that $T_\beta(x)=\beta x\pmod 1$. For each $t\in[0,1)$ let $K_\beta(t)$ be the survivor set consisting of all $x\in[0,1)$ whose orbit $\{T^n_\beta(x): n\ge 0\}$ never hits the open interval $(0,t)$. Kalle et al. proved in [Ergodic Theory Dynam.

Fiber Bundle model with Highly Disordered Breaking Thresholds [PDF]

Phys. Rev. E 91, 032103 (2015), 2015
We present a study of the fiber bundle model using equal load sharing dynamics where the breaking thresholds of the fibers are drawn randomly from a power law distribution of the form $p(b)\sim b^{-1}$ in the range $10^{-\beta}$ to $10^{\beta}$. Tuning the value of $\beta$ continuously over a wide range, the critical behavior of the fiber bundle has ...

Autoantibodies to domain 1 of beta 2 glycoprotein I determined using a novel chemiluminescence immunoassay demonstrate association with thrombosis in patients with antiphospholipid syndrome

Lupus, 2016
Introduction Antibodies to the domain 1 of beta 2 glycoprotein I (β2GPI–D1) have been suggested as a risk marker for thrombosis in patients with the antiphospholipid syndrome (APS).
