Project Abstract Diffuse gliomas are fatal brain tumors that respond poorly to current immunotherapies. Using both mice models and human clinical trial data, we propose a series of experiments to identify immune biomarkers and key immune cell types that predict tumor responsiveness to therapy. These results will further our understanding of brain tumor biology and inform the future development of new treatment modalities.

项目摘要 弥漫性神经胶质瘤是致命的脑肿瘤，对目前的免疫疗法反应不佳。使用 无论是小鼠模型和人类临床试验数据，我们提出了一系列的实验，以确定 免疫生物标志物和关键免疫细胞类型，预测肿瘤对治疗的反应性。 这些结果将进一步加深我们对脑肿瘤生物学的理解，并为未来提供信息。 开发新的治疗模式。
