    Abstract: When stimulated through the T cell receptor(TCR)/CD3 complex without requisite costimulation through the CD28/B7 interaction, T cells enter a state of antigen specific unresponsiveness or anergy. This invention is based, at least in part, on the discovery that signaling though a common cytokine receptor null chain (e.g., interleukin-2 receptor, interleukin-4 receptor, interleukin-7 receptor, interleukin-15 receptor) prevents the induction of T cell anergy. This null chain has been found to be associated with a JAK3 kinase having a molecular weight of about 116 kD (as determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis) and signaling through the null chain induces phosphorylation of the JAK3 kinase. Accordingly, methods for stimulating or inhibiting proliferation by a T cell which expresses a cytokine receptor null chain are disclosed.

    Abstract translation: 当通过CD28 / B7相互作用刺激通过T细胞受体(TCR)/ CD3复合物而没有必要的共刺激时,T细胞进入抗原特异性无反应或无反应的状态。 本发明至少部分地基于以下发现,即通过常见的细胞因子受体γ链(例如白细胞介素-2受体,白介素-4受体,白细胞介素-7受体,白细胞介素-15受体)的信号传导阻止T的诱导 细胞无反应。 已经发现该γ链与具有约116kD分子量(通过十二烷基硫酸钠聚丙烯酰胺凝胶电泳测定)的JAK3激酶相关,并且通过γ链的信号传导诱导JAK3激酶的磷酸化。 因此,公开了用于刺激或抑制表达细胞因子受体γ链的T细胞增殖的方法。
