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.

自1986年我们克隆出白细胞介素-6 （IL-6）作为B细胞刺激因子2以来，IL-6已被报道影响细胞增殖、分化、存活以及成熟细胞功能。STAT3是介导il -6诱导的细胞事件的关键分子。事实上，STAT3在许多肿瘤组织中被激活，STAT3的调暗促进细胞转化，表明STAT3本身可以作为原癌基因。除了肿瘤发生外，IL-6/STAT3轴还影响宿主免疫系统。例如，IL-6/STAT3轴参与toll样受体信号通路、树突状细胞的发育和成熟以及Th17 t细胞亚群的分化。这些事实可能表明，操纵IL-6/STAT3信号可能是多种疾病（如癌症和自身免疫性疾病）的合适靶点。我们积极研究了IL-6/ stat3介导的信号转导的调节机制，以开发新的治疗策略。
