髓样和浆细胞样树突状细胞 (DC) 存在于非炎症性神经系统疾病 (NIND) 的脑脊液 (CSF) 中,并且在临床明确的多发性硬化症 (MS) 和早期 MS – 急性单症状视神经炎 (ON) 中升高。在这里,我们发现,与非炎症对照相比,MS 和 ON 中的血髓样 (CD11c+) DC 中 CCR5 的表达升高,CCR5 是一种调节正常 T 细胞表达和分泌 (RANTES) 激活、调节正常 T 细胞表达和分泌 (RANTES) 和巨噬细胞炎症蛋白 (MIP)-1α/β 的趋化因子受体。相比之下,CXCR4(一种基质细胞衍生因子(SDF)-1α 的受体)的表达在所有组中都相似。 MS 患者的血髓样 DC 对 RANTES 和 MIP-1β 产生趋化反应,这些物质在 MS 病变中表达。在活动性 MS 和 ON 中,血液中髓样 DC 的 CCR5 表达与脑脊液中这些细胞的数量相关。因此,在 MS 和 ON 中,CCR5 的升高可能有助于将髓样 DC 募集至 CSF。浆细胞样 DC 向 CSF 的募集似乎与 CCR5 无关。
Myeloid and plasmacytoid dendritic cells (DC) are present in cerebrospinal fluid (CSF) in non‐inflammatory neurological diseases (NIND) and elevated in clinically definite multiple sclerosis (MS) and in early MS – acute monosymptomatic optic neuritis (ON). Here, we show that expression of CCR5, a chemokine receptor for regulated on activation, normal T cell expressed and secreted (RANTES) and macrophage inflammatory protein (MIP)‐1α/β, is elevated on blood myeloid (CD11c+) DC in MS and ON compared to non‐inflammatory controls. In contrast, expression of CXCR4, a receptor for stromal cell‐derived factor (SDF)‐1α, is similar in all groups. Blood myeloid DC from MS patients respond chemotactically to RANTES and MIP‐1β, which are expessed in MS lesions. In active MS and ON, expression of CCR5 by myeloid DC in blood correlates with numbers of these cells in CSF. Thus, elevation of CCR5 may contribute to recruitment of myeloid DC to CSF in MS and ON. Recruitment of plasmacytoid DC to CSF appears to be CCR5‐independent.
