Induction of early atherosclerosis in LDL-receptor-deficient mice immunized with beta2-glycoprotein I.

BACKGROUND Immunization with beta2-glycoprotein I (beta2GPI), the probable target of autoimmune anticardiolipin antibodies, results in experimental antiphospholipid syndrome in different mouse strains. The present study was undertaken to evaluate the effect of beta2GPI immunization on the progression of atherosclerosis. METHODS AND RESULTS In the first experiment, 3 groups of LDL receptor-def...

Are Oxidized LDL/β2-glycoprotein I Complexes Pathogenic Antigens in Autoimmune-mediated Atherosclerosis?

The oxidative modification of low-density lipoprotein (LDL) in the intima of arteries contributes to the initiation and progression of atherosclerotic lesions. We have previously reported that oxidized LDL (oxLDL) interacts with an endogenous plasma protein, beta2-glycoprotein I (beta2GPI), to form complexes and that the interaction is mediated by oxLDL specific ligands. We have also demonstrat...

Optimization of Unnicked β2-Glycoprotein I and High Avidity Anti-β2-Glycoprotein I Antibodies Isolation

Patient biological material for isolation of β2-glycoprotein I (β2GPI) and high avidity IgG anti-β2-glycoprotein I antibodies (HAv anti-β2GPI) dictates its full utilization. The aim of our study was to evaluate/improve procedures for isolation of unnicked β2GPI and HAv aβ2GPI to gain unmodified proteins in higher yields/purity. Isolation of β2GPI from plasma was a stepwise procedure combining n...

Pro-Atherogenic Oxidized Ldl/β2-Glycoprotein I Complexes in Diabetes Mellitus: Antioxidant Effect

Diabetes mellitus (DM) is the fifth deadliest disease in the United States with an annual economic cost estimated over $100 billion. Cardiovascular disease (CVD) represents the most life threatening consequence of DM accounting for the death of up to 65% of DM patients. Aggressive efforts aimed at treating and controlling the classic CVD risk factors over the last few decades have brought along...
