1393-胶质母细胞瘤肿瘤浸润淋巴细胞:免疫生物学与转化影响

from 聊聊Sci

这篇综述探讨了胶质母细胞瘤 (GBM) 免疫治疗面临的独特挑战,重点分析了肿瘤浸润淋巴细胞 (TILs) 的生物学特性。研究指出,人类患者体内的 TILs 表现与小鼠模型存在显著差异,患者肿瘤中普遍缺乏典型的竭竭性 T 细胞,取而代之的是具有特定功能的 GZMK⁺ T 细胞。这种差异主要归因于 GBM 极低的肿瘤突变负荷和高度抑制的免疫微环境,导致免疫检查点抑制剂在临床试验中表现不佳。文章详细阐述了脑肿瘤免疫循环的运作机制,并评估了新抗原疫苗、过继性细胞疗法及工程化 TCR 等前沿技术。最终,作者强调必须针对 GBM 特有的免疫景观开发个体化方案,通过识别肿瘤特异性 T 细胞来突破治疗瓶颈。References:Hill C M, Nwagwu C D, Odukoya A O, et al.
