树突状细胞(Dendritic cells,DCs)是一种在先天性和获得性免疫应答中发挥重要作用的专职抗原呈递细胞(antigen-presenting cells,APCs)。DC通过调节对病原体的保护性免疫和对自身抗原的耐受性之间的平衡来定向免疫应答。金黄色葡萄球菌(S.金黄色葡萄球菌)是人类皮肤微生物群中的常见成员,并可引起具有显著发病率和死亡率的严重感染。DC对病原体的保护性免疫是清除S.金黄色。树突状细胞通过模式识别受体(PRRs)感知葡萄球菌成分的存在,然后协调免疫系统以解决感染。本文综述了树突状细胞及其Toll样受体在S.金黄色葡萄球菌感染和病原体影响DC活化和功能的策略。
Dendritic cells (DCs) are professional antigen-presenting cells (APCs) that play a crucial role in both innate and adaptive immune responses. DCs orient the immune responses by modulating the balance between protective immunity to pathogens and tolerance to self-antigens. Staphylococcus aureus (S. aureus) is a common member of human skin microbiota and can cause severe infections with significant morbidity and mortality. Protective immunity to pathogens by DCs is required for clearance of S. aureus. DCs sense the presence of the staphylococcal components using pattern recognition receptors (PRRs) and then orchestrate immune systems to resolve infections. This review summarizes the possible roles of DCs, in particular their Toll-like receptors (TLRs) involved in S. aureus infection and strategies by which the pathogen affects activation and function of DCs.
