XCL1, a C class chemokine also known as lymphotactin, is produced by T, NK, and NKT cells during infectious and inflammatory responses, whereas XCR1, the receptor of XCL1, is expressed by a dendritic cell subpopulation. The XCL1-XCR1 axis plays an important role in dendritic-cell-mediated cytotoxic immune response. It has been also shown that XCL1 and XCR1 are constitutively expressed in the thymus and regulate the thymic establishment of self-tolerance and the generation of regulatory T cells. This review summarizes the expression and function of XCL1 and XCR1 in the immune system.
XCL1，一种 C 类趋化因子，也被称为淋趋化因子，在感染和炎症反应期间由 T、NK 和 NKT 细胞产生，而 XCL1 的受体 XCR1，则由树突状细胞亚群表达。XCL1-XCR1 轴在树突状细胞介导的细胞毒性免疫反应中发挥重要作用。也已经表明，XCL1 和 XCR1 在胸腺中持续表达，调节自身耐受的胸腺建立和调节性 T 细胞的产生。这篇综述总结了 XCL1 和 XCR1 在免疫系统中的表达和功能。
