1600-人类胸腺健康与疾病单细胞图谱

from 聊聊Sci

这份研究通过整合多组单细胞核糖核酸测序(scRNA-seq)数据,构建了一个涵盖45万余个细胞的人体胸腺全景图谱。该图谱详尽比较了健康胸腺(胚胎、儿童及成人期)与病理性胸腺(包括胸腺增生和各类胸腺上皮肿瘤)之间的细胞异质性。研究重点识别出了在疾病状态下特异性表达的胸腺上皮细胞(TET_TEC)和成纤维细胞(TET-FB)亚群,并揭示了它们在组织形态发生中的潜在作用。此外,通过分析细胞间通讯,作者发现了A型胸腺瘤中显著增强的APP-CD74信号通路,为相关疾病的诊断和治疗提供了关键的分子靶点。这项工作不仅深化了对胸腺发育与新生物转化过程的理解,也为未来精准医疗提供了宝贵的基础资源。References:Direder M, Wielscher M, Salek M, et al.
