摘要: 【摘要】 朗格汉斯细胞(LC)是表皮内重要的免疫细胞,具有抗原提呈功能,在炎症状态下经过成熟、活化后,迁移至局部淋巴结并活化初始T细胞,启动免疫应答。近年对LC在银屑病发病中的研究显示,LC具有促进炎症和抑制炎症的双重作用。对LC起源的研究显示,LC有两个亚群,分别具有促炎和抑炎作用,参与不同的免疫应答过程,可能与银屑病免疫异常有关。本文综述LC在银屑病中的研究进展。

Abstract: 【Abstract】 Langerhans cells (LC) are important immune cells with antigen-presenting functions in the epidermis. After maturation and activation in an inflammatory state, LC can migrate to local lymph nodes and activate initial T cells to initiate the immune response. Recent studies on the role of LC in pathogenesis of psoriasis have shown that LC play both pro- and anti-inflammatory roles. Studies on the origin of LC have shown that two subsets of LC exert pro- and anti-inflammatory effects respectively, and participate in different immune response processes, which may be related to immune abnormalities in psoriasis. This review systematically elaborates research advances in the role of LC in psoriasis.
