684-脑肿瘤及其转移瘤的特异性微生物群特征研究

from 聊聊Sci

这项研究深入探讨了胶质母细胞瘤(GBM)与脑转移瘤中鲜为人知的肿瘤微生物组特征。研究人员利用成像、培养及测序等多种技术,证实了脑肿瘤内部存在细胞内活性细菌。实验发现,脑转移瘤的微生物丰富度与多样性显著高于GBM,且不同肿瘤类型具有独特的微生物组成与代谢通路。此外,细菌特征呈现出显著的空间差异,大脑后部区域的肿瘤比前部具有更高的微生物多样性。研究还指出,特定的细菌富集(如副球菌属)与脑转移瘤患者较短的生存期相关。这些发现揭示了微生物可能在脑肿瘤的生物学演变及治疗响应中发挥关键作用,为未来的临床转化提供了新方向。References: Gigi E, Gavert N, Raijman-Nagar L, et al.
