Abstract

Official abstract text for this publication.

The invention features compositions and methods of using a dimeric inhibitor, e.g., A1-A1, to selectively target β2GPI in β2GPI/antibody complexes. The compositions can be administered to subjects (e.g., a mammal, such as a human) having or likely to develop APS, or one or more symptoms of APS, in order to treat or inhibit the disease or treat or reduce its symptoms. The inhibitors of the invention include two ligand-binding A1 modules, e.g., from ApoER2, connected by a flexible linker.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of treating antiphospholipid syndrome in a subject in need thereof comprising administering a composition comprising a polypeptide, wherein said polypeptide comprises a first low density lipoprotein (LDL) receptor-type A (LA) module, a second LA module, and a linker that joins said first LA module to said second LA module; and wherein said first LA module comprises a first A1 domain comprising an amino acid sequence with 85% or more sequence ident…
