Abstract

It has been recently shown that systemically injected neural precursor cells (NPCs) could cross brain endothelium and favor functional recovery in animal models of multiple sclerosis (MS). Here we show that human NPCs express receptors of the chemokines IL8 and CXCL13 (CXCR1 and CXCR5, respectively) and migrate across brain endothelial cells in vitro, in response to these chemokines. Considering that these chemokines have been found overexpressed in MS in active, but not inactive areas of demyelination, our data suggest that systemically injected human NPCs may be considered for targeting active areas of demyelination in therapeutic approaches of MS.

摘要

最近有研究表明,系统性注射神经前体细胞(NPCs)可以穿透血脑屏障,并有利于多发性硬化症(MS)动物模型的功能恢复。在这里,我们发现人类 NPCs 表达趋化因子 IL8 和 CXCL13 的受体(分别为 CXCR1 和 CXCR5),并在体外响应这些趋化因子穿透血脑内皮细胞迁移。鉴于这些趋化因子在 MS 中活性脱髓鞘区域过度表达,但在非活性区域不表达,我们的数据表明,在 MS 的治疗方法中,系统注射的人 NPCs 可被视为针对脱髓鞘的活性区域。
