中英文说明丨InVivoMAb 抗小鼠 IL-4介绍

The 11B11 monoclonal antibody reacts with mouse IL-4 (interleukin-4) a multifunctional 14 kDa cytokine. IL-4 is expressed primarily by activated Th2 cells and NK cells, and at lower levels by mast cells, and basophils. IL-4 signals through the IL-4Rα. Upon receptor binding IL-4 stimulates activated B and T lymphocyte proliferation, and the differentiation of B cells into plasma cells. It also induces B cell class switching to IgE, and up-regulates MHC class II production while decreasing the production of Th1 cells, macrophages, IFNγ, and dendritic cell IL-12. Like other Th2 associated cytokines, IL-4 is involved in the airway inflammation observed in the lungs of patients with allergic asthma. The 11B11 monoclonal antibody has been shown to neutralize the bioactivity of natural or recombinant IL-4.

11B11单克隆抗体与小鼠IL-4（白细胞介素-4）反应，这是一种多功能14kDa细胞因子。IL-4主要由活化的Th2细胞和NK细胞表达，在较低水平上由肥大细胞和嗜碱性粒细胞表达。IL-4通过IL-4Rα发出信号。受体结合后，IL-4刺激活化的B和T淋巴细胞增殖，以及B细胞分化为浆细胞。它还诱导B细胞类切换到IgE，并上调MHC II类的产生，同时减少Th1细胞，巨噬细胞，IFNγ和树突状细胞IL-12的产生。与其他Th2相关细胞因子一样，IL-4参与过敏性哮喘患者肺部观察到的气道炎症。11B11单克隆抗体已被证明可以中和天然或重组IL-4的生物活性。
