    • The present invention relates to humanized FcγRIIB antibodies, fragments, and variants thereof that bind human FcγRIIB with a greater affinity than said antibody binds FcγRIIA. The invention encompasses the use of the humanized antibodies of the invention for the treatment of any disease related to loss of balance of Fc receptor mediated signaling, such as cancer, autoimmune and inflammatory disease. The invention provides methods of enhancing the therapeutic effect of therapeutic antibodies by administering the humanized antibodies of the invention to enhance the effector function of the therapeutic antibodies. The invention also provides methods of enhancing the efficacy of a vaccine composition by administering the humanized antibodies of the invention. The invention encompasses methods for treating an autoimmune disease and methods for elimination of cancer cells that express FcγRIIB.
    • 本发明涉及以比所述抗体结合FcγRIIA更大的亲和力结合人FcγRIIB的人源化FcγRIIB抗体,其片段和变体。 本发明包括本发明的人源化抗体用于治疗与Fc受体介导的信号传导的平衡丧失有关的任何疾病(例如癌症,自身免疫性和炎症性疾病)的用途。 本发明提供了通过施用本发明的人源化抗体来增强治疗性抗体的治疗效果以增强治疗性抗体的效应子功能的方法。 本发明还提供了通过施用本发明的人源化抗体来增强疫苗组合物的功效的方法。 本发明包括治疗自身免疫性疾病的方法和用于消除表达FcγRIIB的癌细胞的方法。

    • The present invention is directed to diabody molecules and uses thereof in the treatment of a variety of diseases and disorders, including immunological disorders, infectious disease, intoxication and cancers. The diabody molecules of the invention comprise two polypeptide chains that associate to form at least two epitope binding sites, which may recognize the same or different epitopes on the same or differing antigens. Additionally, the antigens may be from the same or different molecules. The individual polypeptide chains of the diabody molecule may be covalently bound through non-peptide bond covalent bonds, such as, but not limited to, disulfide bonding of cysteine residues located within each polypeptide chain. In particular embodiments, the diabody molecules of the present invention further comprise an Fc region, which allows antibody-like functionality to engineered into the molecule.
    • 本发明涉及双抗体分子及其在治疗各种疾病和病症(包括免疫学疾病,感染性疾病,中毒和癌症)中的用途。 本发明的双抗体分子包含两个缔合以形成至少两个表位结合位点的多肽链,其可识别相同或不同抗原上相同或不同的表位。 另外,抗原可以来自相同或不同的分子。 双抗体分子的单个多肽链可以通过非肽键共价键共价结合,例如但不限于位于每个多肽链内的半胱氨酸残基的二硫键。 在具体实施方案中,本发明的双抗体分子还包含Fc区,其允许抗体样功能被改造成分子。

    • An article for culturing cells includes a substrate on which cells can be cultured. The substrate has a base surface. An array of projections extends from the base surface. The projections have a height of about 1 micrometer to about 100 micrometers, and have a gap distance along the major surface from center to center between neighboring projections of about 10 micrometers to 80 micrometers. A plurality of arrays of projections may extend from the surface with gaps in the base surface between the arrays. Hepatocytes cultures on such microprojection array substrates maintained in vivo like morphology and membrane polarity. Hepatocytes co-cultured with helper cells on such substrates tended to grow in the area of the arrays, while the helper cells tended to grow in the areas between the arrays.
    • 培养细胞的制品包括可以培养细胞的底物。 基板具有基面。 一组突起从基面延伸出来。 突起具有约1微米至约100微米的高度,并且在约10微米至80微米的相邻突起之间具有从中心到中心的主表面的间隙距离。 多个突起阵列可以从阵列之间的基部表面中的间隙从表面延伸。 在这样的微喷射阵列基板上的肝细胞培养物保持体内,如形态和膜极性。 与这种底物上的辅助细胞共培养的肝细胞趋向于在阵列区域中生长,而辅助细胞趋向于在阵列之间的区域中生长。
