Transplantation of genetically modified oligodendrocyte progenitor cells (OPCs) into a mouse model of MS improves remyelination, new research has demonstrated. The researchers used CRISPR in human embryonic stem cell-derived OPCs to delete neuropilin 1, a receptor for SEMA3A that is highly expressed in demyelinated lesions in people with MS and is chemorepulsive to OPCs. Transplantation of the modified OPCs enhanced remyelination in the mice, providing proof of concept for OPC transplantation as a potential therapeutic strategy for MS.

用于 MS 的少突胶质细胞祖细胞移植



新的研究表明,将转基因少突胶质细胞祖细胞 (OPC) 移植到 MS 小鼠模型中可改善髓鞘再生。研究人员在人胚胎干细胞衍生的 OPC 中使用 CRISPR 来删除神经纤毛蛋白 1,神经纤毛蛋白 1 是 SEMA3A 的一种受体,在 MS 患者的脱髓鞘病变中高度表达,并且对 OPC 具有化学脉冲性。移植修饰的 OPC 增强了小鼠的髓鞘再生,为 OPC 移植作为 MS 的潜在治疗策略提供了概念证明。
