               [摘   要] 赖氨酸特异性去甲基化酶 6B(lysine⁃specific demethylase 6B,KDM6B)是含 Jumonji C 结构域蛋白家族(Jumonji C
                domain⁃containing protein family,JmjC)中的一种重要表观遗传因子,不仅在细胞分化、炎症反应、组织稳态和神经性疾病中发挥表
                观遗传调控作用,还对巨噬细胞的功能、免疫反应等具有关键调控意义。作为 JmjC 家族中唯一能响应类 Toll 受体(Toll⁃like
                receptor,TLR)信号的成员,KDM6B 可在 TLR 信号刺激下被激活从而发挥功能。研究发现,KDM6B可以通过调节巨噬细胞的
                极化、影响细胞因子的表达水平以及参与肿瘤微环境调控等方式影响巨噬细胞,因此,KDM6B在免疫反应、炎症反应以及肿瘤
                等病理生理过程中发挥重要作用。KDM6B作为关键的表观遗传因子对巨噬细胞的功能具有调控作用,包括调节巨噬细胞的
                极化、炎症反应以及促纤维化等,有望成为研究免疫、炎症及肿瘤等相关疾病的潜在靶点。

               [Abstract] Lysine⁃specific demethylase 6B(KDM6B)is an important epigenetic factor in the Jumonji C domain⁃containing protein
                family(JmjC). It not only plays an epigenetic role in cell differentiation,inflammatory response,tissue homeostasis,and neurological
                diseases,but also plays an important role in macrophage function and immune response. KDM6B is the sole member of the JmjC family
                that can respond to Toll ⁃ like receptor(TLR)signals. It is activated under the stimulation of TLR signals and thereby fulfills its
                function. Studies have found that KDM6B can affect macrophages by regulating the polarization of macrophages,affecting the
                expression of cytokines and participating in the regulation of tumor microenvironment. Therefore,KDM6B plays an important role in
                the physiological and pathological processes such as immune response,inflammatory response,and tumor. As a key epigenetic factor,
                KDM6B regulates the functions of macrophages,including the polarization,inflammatory response,and pro ⁃ fibrotic activities of
                macrophages,and is expected to become a potential target for the study of immune,inflammatory,and tumor⁃related diseases.
