    • The present invention relates to methods of treating or preventing cancer and other diseases using molecules, particularly polypeptides, more particularly immunoglobulins (e.g., antibodies), comprising a variant Fc region, wherein said variant Fc region comprises at least one amino acid modification relative to a wild-type Fc region, which variant Fc region binds an Fc?R that activates a cellular effector ("Fc?Ractivating," such as Fc?RIIA or Fc?RIIIA) and an Fc?R that inhibits a cellular effector ("Fc?Rinhibiting" such as Fc?RIIA) with an altered Ratio of Affinities relative to the respective binding affinities of such Fc?R for the Fc region of the wild-type immunoglobulin. The methods of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection where either an enhanced efficacy of effector cell function mediated by Fc?R is desired (e.g., cancer, infectious disease) or an inhibited effector cell response mediated by Fc?R is desired (e.g., inflammation, autoimmunde disease).
    • 本发明涉及使用分子,特别是多肽,特别是包含变体Fc区的免疫球蛋白(例如抗体)治疗或预防癌症和其它疾病的方法,其中所述变体Fc区包含至少一个相对于 野生型Fc区,该变体Fc区结合激活细胞效应子(“FcγRactivation”,例如FcγRIIA或FcγRIIIA)的FcγR和抑制细胞效应子(Fc)的FcγR 抑制野生型免疫球蛋白Fc区的FcγR的相对结合亲和力的改变的亲和力比例如FcγRIIA。 本发明的方法特别可用于预防,治疗或改善与需要由FcγR介导的效应细胞功能的增强功效的疾病,病症或感染相关的一种或多种症状(例如,癌症,感染性 疾病)或由FcγR介导的受抑制的效应细胞应答是期望的(例如炎症,自身免疫疾病)。

    • The present invention provides methods of treating, preventing or ameliorating the symptoms of Latent Autoimmune Diabetes in Adults (LADA) and adult-onset type 1 diabetes through the use of anti-human CD3 antibodies. In particular, in invention provides methods of preventing or delaying insulin requirement in patients diagnosed with LADA. The methods of the invention provide for administration of antibodies that specifically bind the epsilon subunit within the human CD3 complex. Such antibodies modulate the T cell receptor/alloantigen interaction and, thus, regulate the T cell mediated cytotoxicity associated with autoimmune disorders. Additionally, the invention provides for modification of the anti-human CD3 antibodies such that they exhibit reduced or eliminated effector function and T cell activation as compared to non-modified anti-human CD3 antibodies.
    • 本发明提供了通过使用抗人CD3抗体来治疗,预防或改善成人隐匿性自身免疫糖尿病(LADA)和成人发病1型糖尿病的症状的方法。 具体而言,本发明提供了在被诊断患有LADA的患者中预防或延迟胰岛素需求的方法。 本发明的方法提供了特异性结合人CD3复合物内的ε亚基的抗体的施用。 这种抗体调节T细胞受体/同种异体抗原相互作用,从而调节与自身免疫病相关的T细胞介导的细胞毒性。 此外,本发明提供了修饰抗人CD3抗体,使得与未修饰的抗人CD3抗体相比,它们表现出减少的或消除的效应子功能和T细胞活化。
