树突状细胞(DC)是一个异质性群体。小鼠树突状细胞包括常规树突状细胞和浆细胞样树突状细胞。在人类中,类似的群体是髓系树突状细胞(MDCS)和pDC。尽管在表型和功能上不同,但研究表明,这些DC亚群在免疫反应过程中可能相互作用或‘串扰’。例如,CDC可以促进PDC的成熟,而PDC在某些致病条件下可能会增强CDC的抗原提呈,甚至本身就具有CDC表型。树突状细胞在非感染性葡萄膜炎中的作用主要是在实验性自身免疫性葡萄膜炎小鼠模型中进行的研究,在患者中的研究程度较有限。最近的证据表明,在本病中DC亚群的数量、表型和功能都发生了改变。我们对PDCs和CDCs/MDCS的最新进展进行了综述,特别关注了它们之间的相互作用以及DC亚群在非感染性葡萄膜炎中的双重作用。
Dendritic cells (DCs) are a heterogeneous population. Murine DCs consist of conventional DCs (cDCs) and plasmacytoid DCs (pDCs). In human, the analogous populations are myeloid DCs (mDCs) and pDCs. Though distinct in phenotypes and functions, studies have shown that these DC subsets may interact or ‘crosstalk’ during immune responses. For example, cDCs may facilitate pDC maturation, while pDCs may enhance antigen presentation of cDCs in certain pathogenic conditions or even take on a cDC phenotype themselves. The role of DCs in non-infectious uveitis has been studied primarily in the experimental autoimmune uveitis mouse model and to a more limited extent in patients. Recent evidence shows that the number, phenotype and function of DC subsets are altered in this disease. We provide an overview of selected recent developments of pDCs and cDCs/mDCs, with special attention to their interaction and the dual roles of DC subsets in non-infectious uveitis.
