Modeling native and seeded Synuclein aggregation and related cellular dysfunctions in dopaminergic neurons derived by a new set of isogenic iPSC lines with SNCA multiplications.

SNCA 基因三倍体是早发型、侵袭性帕金森病的罕见遗传病因。本研究从两名携带新近报道的紧凑 SNCA 三倍体、表现为严重运动障碍、精神症状和认知下降的同胞患者外周血单核细胞出发，利用非整合仙台病毒重编程获得诱导多能干细胞（iPSC）。通过 CRISPR/Cas9 在每条 SNCA 拷贝中引入移码 indel 突变，构建了从 4 个到...
