    • The present invention concerns antigen binding proteins that bind TL1A, including bispecific antigen binding proteins (e.g., antibodies) to TL1A and TNF-α. Such bispecific antibodies can be in a tetrameric immunoglobulin format, in which one heavy chain-light chain pair of the antibody is directed to TL1A and the other to TNF-α. The bispecific antigen binding proteins may also be comprised in an IgG-scFv fusion, in which a conventional tetrameric antibody directed to one antigen is fused to a pair of single chain Fv units directed to the other. The bispecific antigen binding protein may also be comprised in an IgG-Fab fusion, in which a Fab molecule that binds to one antigen is fused to each heavy chain of a conventional tetrameric antibody directed to the other antigen. The invention further relates to uses of the anti-TL1A binding proteins and anti-TL1A/anti-TNF-alpha antigen binding proteins, and pharmaceutical formulations thereof.
    • 本发明涉及结合TL1A的抗原结合蛋白,包括TL1A和TNF-α的双特异性抗原结合蛋白(例如抗体)。 这样的双特异性抗体可以是四聚体免疫球蛋白形式,其中抗体的一个重链 - 轻链对针对TL1A而另一个针对TNF-α。 双特异性抗原结合蛋白也可以包含在IgG-scFv融合物中,其中针对一种抗原的常规四聚体抗体与针对另一种抗原的一对单链Fv单元融合。 双特异性抗原结合蛋白也可以包含在IgG-Fab融合物中,其中与一种抗原结合的Fab分子与针对另一种抗原的常规四聚体抗体的每种重链融合。 本发明进一步涉及抗TL1A结合蛋白和抗TL1A /抗TNF-α抗原结合蛋白及其药物制剂的用途。
