摘要： 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.

摘要： 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.
