    摘要： The invention provides methods for modulating an immune response comprising contacting an immune cell with an agent that modulates BTF4 or B7-L1 mediated signaling. BTF4 or B7-L1 mediated signaling may either be increased, to thereby downregulate the immune response, or alternatively may be decreased, to upregulate the immune response. Modulation may be either activation or inhibition, and contacting may occur in vivo or in vitro. Performance of this method in vivo is also potentially therapeutic for an individual who may benefit from the upregulation or downregulation of an immune response. Such modulation to downregulate the immune response serves as a therapeutic e.g., for an individual who has received an organ transplant, or has a condition such as an allergy, or an autoimmune disorder. Alternatively, modulation to upregulate the immune response serves as a therapeutic for an individual, e.g., who has a condition such as an immunosuppressive disorder or a tumor. Methods for identifying an agent that modulates BTF4 signaling or B7-L1 signaling is also provided.

    摘要翻译： 本发明提供了调节免疫应答的方法，包括使免疫细胞与调节BTF4或B7-L1介导的信号传导的药剂接触。 可以增加BTF4或B7-L1介导的信号传导，从而下调免疫应答，或者可以减少上调免疫应答。 调节可以是活化或抑制，并且接触可以在体内或体外发生。 该方法在体内的表现对于可能受益于免疫反应的上调或下调的个体也是潜在的治疗剂。 用于下调免疫应答的这种调节用作治疗剂，例如对于已经接受器官移植或具有诸如过敏或自身免疫病症的病症的个体。 或者，用于上调免疫应答的调节用作个体的治疗剂，例如患有诸如免疫抑制障碍或肿瘤的病症的个体。 还提供了用于识别调节BTF4信令或B7-L1信令的试剂的方法。
