    • Methods are disclosed herein for specifically inducing proliferation of CD4+ T cells. The methods are of use in treating immunodeficiencies, such as an immunodeficiency produced by infection with an immunodeficiency virus, such as infection with a human immunodeficiency virus (HIV). The methods include contacting isolated mammalian CD4+ T cells with an effective amount of a thymic stromal derived lymphopoietin (TSLP) polypeptide or a therapeutically effective amount of nucleic acid encoding the TSLP polypeptide, thereby inducing proliferation of the T cells. Methods are also disclosed for treating an IgE mediated disorder, such as asthma. The methods include administering to a subject a therapeutically effective amount of a TSLP antagonist. Transgenic mice are also disclosed herein. The somatic and germ cells of these mice include a disrupted thymic stromal lymphopoietin receptor (TSLP) gene, the disruption being sufficient to inhibit the interaction of TSLP with its receptor, and a disrupted γc gene, the disruption being sufficient to reduce signaling through the γc. The mice exhibit diminished thymic cellularity. Methods of using these mice for drug screening are also disclosed.
    • 本文公开了特异性诱导CD4 + T细胞增殖的方法。 该方法可用于治疗免疫缺陷,例如由免疫缺陷病毒感染产生的免疫缺陷,例如人免疫缺陷病毒(HIV)的感染。 所述方法包括使分离的哺乳动物CD4 + T细胞与有效量的胸腺基质衍生的淋巴细胞生成素(TSLP)多肽或治疗有效量的编码TSLP多肽的核酸接触,从而诱导T细胞的增殖。 还公开了用于治疗IgE介导的病症如哮喘的方法。 所述方法包括向受试者施用治疗有效量的TSLP拮抗剂。 本文还公开了转基因小鼠。 这些小鼠的体细胞和生殖细胞包括破坏的胸腺基质淋巴细胞生成素受体(TSLP)基因,破坏足以抑制TSLP与其受体的相互作用,以及破坏的γc基因,破坏足以减少通过γc的信号转导 。 小鼠表现出胸腺细胞减少。 还公开了将这些小鼠用于药物筛选的方法。

    • A transgenic mouse is disclosed herein whose somatic and germ cells comprise a disrupted IL-21 receptor gene, the disruption being sufficient to inhibit the binding of IL-21 to an IL-21 receptor, and a disrupted IL-4 gene, the disruption being sufficient to inhibit the production of IL-4 or the binding of IL-4 to the IL-4 receptor. A mouse homozygous for the disrupted IL-21 receptor gene and homozygous for the disrupted IL-4 gene has diminished B cell function. A method is disclosed for altering a B cell activity. The method includes administering a therapeutically effective amount of an agent that interferes with the interaction of IL-21 with an IL-21 receptor, thereby altering the B cell activity. A method is also disclosed for of treating a subject with Job's disorder or atopic disease. A method is also disclosed for treating or preventing an allergic reaction in a subject. A method is also disclosed for treating a subject with an autoimmune or antibody mediated disorder.
    • 本文公开了一种转基因小鼠,其体细胞和生殖细胞包含破坏的IL-21受体基因,所述破坏足以抑制IL-21与IL-21受体的结合以及破坏的IL-4基因,所述破坏是 足以抑制IL-4的产生或IL-4与IL-4受体的结合。 对于破坏的IL-21受体基因纯合的小鼠和破坏的IL-4基因是纯合的,具有减少的B细胞功能。 公开了用于改变B细胞活性的方法。 该方法包括施用治疗有效量的干扰IL-21与IL-21受体相互作用的试剂,由此改变B细胞活性。 还公开了用于治疗患有约瑟病或特应性疾病的受试者的方法。 还公开了用于治疗或预防受试者的过敏反应的方法。 还公开了用自身免疫或抗体介导的病症治疗受试者的方法。
