The prominent role of tolerogenic dendritic cells (tolDCs) in promoting immune tolerance and the development of efficient methods to generate clinical grade products allow the application of tolDCs as cell-based approach to dampen antigen (Ag)-specific T cell responses in autoimmunity and transplantation. Interleukin (IL)-10 potently modulates the differentiation and functions of myeloid cells. Our group contributed to the identification of IL-10 as key factor in inducing a subset of human tolDCs, named dendritic cell (DC)-10, endowed with the ability to spontaneously release IL-10 and induce Ag-specific T regulatory type 1 (Tr1) cells. We will provide an overview on the role of IL-10 in modulating myeloid cells and in promoting DC-10. Moreover, we will discuss the clinical application of DC-10 as inducers of Ag-specific Tr1 cells for tailoring Tr1-based cell therapy, and as cell product for promoting and restoring tolerance in T-cell-mediated diseases.
耐受性树突状细胞(tolDCs)在促进免疫耐受中的突出作用,以及生成高效临床级产品的方法的发展,使得 tolDCs 可以作为一种基于细胞的方法,用于抑制自身免疫和移植中的抗原(Ag)特异性 T 细胞反应。白细胞介素(IL)-10 可强力调节髓样细胞的分化和功能。我们的研究小组发现 IL-10 是诱导人 tolDC 亚群(称为 DC-10)的关键因素,DC-10 具有自发释放 IL-10 和诱导 Ag 特异性调节性 T 细胞 1(Tr1)的能力。我们将概述 IL-10 在调节髓样细胞和促进 DC-10 中的作用。此外,我们将讨论 DC-10 作为诱导 Ag 特异性 Tr1 细胞的应用,用于定制基于 Tr1 的细胞治疗,以及作为促进和恢复 T 细胞介导疾病中耐受性的细胞产品。
