Since we cloned interleukin-6 (IL-6) as B cell stimulatory factor 2 in 1986, IL-6 has been reported to influence cell proliferation, differentiation, and survival as well as mature cell functions. Signal transducer and activator of transcription 3 (STAT3) is a key molecule to mediate IL-6-induced cellular events. Indeed, STAT3 is activated in many tumor tissues, and the dimmer of STAT3 promotes cellular transformation, indicating that STAT3 itself can act as a proto-oncogene. In addition to oncogenesis, IL-6/STAT3 axis influences host immune systems. For example, IL-6/STAT3 axis is involved in the Toll-like receptor signaling pathways, the development and maturation of dendritic cells, and the differentiation of Th17 T-cell subset. These facts are likely to suggest that manipulation of IL-6/STAT3 signals could be suitable target for a variety of disease such as cancer and autoimmune diseases. We have energetically examined regulatory mechanisms of IL-6/STAT3-mediated signal transduction for the development of novel therapeutic strategies.

由于我们将白介素-6（IL-6）克隆为1986年的B细胞刺激因子2，因此据报道IL-6会影响细胞的增殖，分化和存活以及成熟的细胞功能。转录3（STAT3）的信号换能器和激活因子是介导IL-6诱导的细胞事件的关键分子。实际上，在许多肿瘤组织中激活了STAT3，STAT3的变暗器促进了细胞转化，表明STAT3本身可以充当原始癌基因。除肿瘤发生外，IL-6/STAT3轴还会影响宿主免疫系统。例如，IL-6/STAT3轴参与类似收费的受体信号通路，树突状细胞的发育和成熟以及Th17 T细胞子集的分化。这些事实可能表明，操纵IL-6/STAT3信号可能是癌症和自身免疫性疾病等多种疾病的合适靶标。我们已经精力研究了IL-6/STAT3介导的信号转导的调节机制，以开发新的治疗策略。
