CD81 通过阻断 CD274/PD-L1 的选择性自噬降解驱动放射抵抗性胶质母细胞瘤的免疫逃逸
CD81 drives immune evasion in radioresistant glioblastoma by blocking selective autophagic degradation of CD274/PD-L1.
我们的工作确立了CD81作为连接放射抵抗与免疫逃逸的关键桥梁,其通过维持GBM中CD274的丰度发挥作用,并突显CD81作为优化放射免疫治疗的有前景的治疗靶点。

这是一项分期未标注的注册临床试验,评估细胞治疗用于脑肿瘤的安全性、可行性及初步疗效。当前状态:招募中。计划入组 500 例。试验地点:中国 · 台北(共 1 个中心,其中中国 1 个)。登记号:NCT05921786。
不限性别 · ≥ 18 Years
入选标准: 1. 年龄>18岁,确诊脑部疾病(新诊断或复发),适合并愿意接受切除手术。 排除标准: 1. 无法提供参加研究的知情同意。 2. 肿瘤样本经标准病理流程仍无法获得明确病理诊断。 3. 仅接受活检而非切除手术。 4. 病理检查提示明显放疗后改变或放射性坏死。
Inclusion Criteria: 1\. Patients older than the age of 18 with diagnosis of brain disease (both newly-diagnosed or recurrent) who are suitable and willing to receive resection surgery. Exclusion Criteria: 1. Patients who cannot give consent to participate in the study. 2. The tumor samples failed to give a conclusive pathological diagnosis by standard pathological workflow. 3. Patients who only receives biopsy surgery rather than resection surgery. 4. Significant post-irradiation effect or radiation necrosis reported in the pathological examination.

主要终点:Acquire neuronal structual (image frame) results of different brain regions · By interpreting the microscopic images of different brain regions' tissues , an attempt is made to understand the structure of brain disease tissues (via cell morphology, microvessels, etc). · 3 years;Acquire electrophysiological readout (voltage amplitude, mV) datas of different brain regions · By interpreting the neuron electric reactive datas, an attempt is made to know the neuronal activity (via detecting voltage amplitude change) between multiple neurons. · 3 years
次要终点:To conduct imaging for multiple types of human brain tissues and construct the neuron image database
本研究旨在建立多种脑组织的大型数据库,并验证人脑组织模型及 hiPSC 来源类器官模型的相关性。
The research aims to establish a big database of multiple kinds of brain tissues and prove the relevance of human brain tissue models and hiPSCs-derived organoid models.
