    • The present invention relates to a method for producing patient specific anti-cancer antibodies using a novel paradigm of screening. By segregating the anti-cancer antibodies using cancer cell cytotoxicity as an end point, the process makes possible the production of anti-cancer antibodies customized for the individual patient that can be used for therapeutic and diagnostic purposes. The invention further relates to the process by which the antibodies are made and to their methods of use. The antibodies can be made specifically for one tumor derived from a particular patient and are selected on the basis of their cancer cell cytotoxicity and simultaneous lack of toxicity for non-cancerous cells. The antibodies can be used in aid of staging and diagnosis of a cancer, and can be used to treat tumor metastases. The anti-cancer antibodies can be conjugated to red blood cells obtained from that patient and re-infused for treatment of metastases based upon the recognition that metastatic cancers are usually well vascularized and the delivery of anti-cancer antibodies by red blood cells can have the effect of concentrating the antibodies at the site of the tumor.
    • 本发明涉及使用新的筛选范例来生产患者特异性抗癌抗体的方法。 通过使用癌细胞细胞毒性分离抗癌抗体作为终点,该方法使得可以为可用于治疗和诊断目的的个体患者定制抗癌抗体。 本发明还涉及制备抗体的方法及其使用方法。 抗体可以专门针对来自特定患者的一种肿瘤进行制备,并且基于它们的癌细胞细胞毒性和对非癌细胞同时缺乏毒性进行选择。 抗体可用于帮助分期和诊断癌症,并可用于治疗肿瘤转移。 抗癌抗体可以与从该患者获得的红细胞结合,并且基于认识到转移性癌症通常是良好血管化并且红细胞递送抗癌抗体可以具有 将抗体集中在肿瘤部位的作用。

    • Reactivity between an alloantigen and an anti-alloantigen is indicative of immunological reactivity between two biological samples of the same species. Reactivity between a xenoantigen and an anti-xenoantigen is indicative of immunological reactivity between two biological samples of different species. In many cases both of the reactions are indicative of an antibody-mediated rejection. Anti-antibodies can be employed to reduce cross-reactivity in many transplantation-type situations, either within a similar species, or across species lines. These anti-antibodies are prepared against the antibodies responsible for the antibody-mediated rejection. These anti-antibodies can then be used in vivo or in vitro to complex with the antibodies thus reducing or eliminating reactivity between an alloantigen and an anti-alloantigen or reactivity between a xenoantigen and an anti-xenoantigen between any two species combinations. These antibodies may also be used to target and eliminate the B-cells that produce anti-xenogenic antibodies.
    • 同种异体抗原和抗同种异体抗原之间的反应性指示相同物种的两个生物样品之间的免疫反应性。 异种抗原和抗异种抗原之间的反应性指示不同物种的两个生物样品之间的免疫反应性。 在许多情况下,两种反应均表明抗体介导的排斥反应。 可以使用抗抗体来减少许多移植类型的情况下的交叉反应性,不管是在相似的物种内还是在物种种类之间。 针对负责抗体介导的排斥反应的抗体制备这些抗体。 然后,这些抗体可以在体内或体外用于与抗体复合,从而减少或消除任何两种物种组合之间异种抗原和抗同种异体抗原之间的反应性或异种抗原与抗异种抗原之间的反应性。 这些抗体也可用于靶向和消除产生抗异种抗体的B细胞。
