简介：[摘要 ]： JAK/STAT信号通路参与体内多种细胞的增殖、分化及免疫调节等过程，这一通路更参与与造血干细胞的存活、增殖、分化等有关的细胞因子的表达。当信号通路过度激活时，将与多种血液系统疾病密切相关。芦可替尼是一种非选择性 JAK1/2抑制剂，可有效阻断 JAK/STAT信号通路过度激活，在治疗相关疾病中发挥不容忽视的作用。本文就此进行综述。

简介：摘要JAK/STAT信号通路在皮肌炎发病中起着重要作用。JAK抑制剂能阻断依赖JAK/STAT通路相关因子的信号转导，抑制免疫细胞激活和T细胞介导的炎症性反应。目前美国食品药品监督管理局批准的JAK抑制剂适应证只有风湿性关节炎和骨髓纤维化，但已有不少应用JAK抑制剂治疗难治性皮肌炎的报道。本文综述JAK/STAT通路在皮肌炎发病机制中的作用、JAK抑制剂治疗皮肌炎的作用机制及临床应用。
