| abstract |
The present invention provides domain 1 β2GPI polypeptides, polynucleotides encoding these polypeptides, mimetics of these polypeptides, and methods using domain 1 β2GPI polypeptides and mimetics. Domain 1 of β2GPI has been shown to bind to anti-cardiolipin (β2GPI-dependent antiphospholipid) antibodies, which are associated with several pathologies, such as thrombosis and fetal loss. The domain 1 β2GPI polypeptides may be used to detect β2GPI-dependent antiphospholipid antibodies in a sample. The invention further provides methods of inducing tolerance using these domain 1 β2GPI polypeptides. |
