IgE是特应性疾病中的关键效应分子;然而,对IgE B细胞中IgE产生的调节机制仍知之甚少。在本研究中,我们证明,JSI-124(葫芦素I),选择性STAT 3抑制剂,选择性抑制IgE的产生由人IgE B细胞系,CRL-8033细胞,而不影响IgG的产生由IgG B细胞系。在分子机制方面,我们发现JSI-124对Ig λ基因表达有抑制作用,但对Ighe基因表达无影响。JSI-124的上述作用不是通过影响细胞增殖或凋亡介导的。此外,多个B细胞分化相关基因的表达没有受到JSI-124的显著影响。总之,我们证明了一种潜在的策略,治疗抑制IgE的生产,而不影响过敏性患者的IgG生产。
IgE is a key effector molecule in atopic diseases; however, the regulation mechanisms of IgE production in IgE B cells remain poorly understood. In the present study, we demonstrate that JSI-124 (cucurbitacin I), a selective STAT3 inhibitor, selectively inhibits production of IgE by a human IgE B cell line, CRL-8033 cells, while does not affect the IgG production by IgG B cell lines. In the aspect of molecular mechanism, we found thatIgλ, but notIghe, gene expression was suppressed by JSI-124. The above effects of JSI-124 were not mediated by affecting cellular proliferation or apoptosis. Furthermore, multiple B cell differentiation-related genes expression was not significantly affected by JSI-124. Taken together, we demonstrate a potential strategy of therapeutically suppressing IgE production without affecting IgG production in atopic patients.
