IL13 induces the same biological effects as IL4 in normal human B cells. We show that as in the IL4R complex, both IL4R alpha and IL2R gamma c are components of the IL13R and that both cytokines induced STAT6, STAT3 and STAT5 activation in B cells. In spite of this similar downstream signalling, IL4 and IL13 used a different set of Janus kinases: IL13 is unable to activate JAK1 and JAK3.
白细胞介素13(IL13)在正常人B细胞中诱导与白细胞介素4(IL4)相同的生物学效应。我们发现,与IL4受体复合物一样,IL4受体α和IL2受体γc都是IL13受体的组成部分,并且这两种细胞因子均可诱导B细胞中的信号转导和转录激活因子6(STAT6)、信号转导和转录激活因子3(STAT3)以及信号转导和转录激活因子5(STAT5)活化。尽管存在这种相似的下游信号传导,但IL4和IL13使用了不同的一组Janus激酶:IL13无法激活JAK1和JAK3。
