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。

III期、多中心、安慰剂对照临床试验,采用序贯随机分组,旨在评估杂交树突状细胞(DC)实验性疫苗治疗胶质母细胞瘤的疗效和安全性。研究在圣保罗大学医学院临床医院(HCFMUSP)和圣保罗大学生物医学科学研究所(ICB/USP)开展,由José Alexandre Marzagão Barbuto教授牵头,神经外科、病理学、血液学等多学科研究团队参与。研究旨在确定完成手术、化疗和放疗等标准治疗的成人胶质母细胞瘤患者接受杂交DC疫苗后是否可提高总生存期。次要目标包括评估无进展生存期、生活质量、免疫反应和干预安全性。计划入组186例并随机分为三组:安慰剂对照组、DC疫苗组、DC疫苗联合帕博利珠单抗组。
This Phase III, multicenter, placebo-controlled clinical trial with sequential randomization is designed to evaluate the efficacy and safety of an experimental vaccine composed of hybrid dendritic cells (DCs) for the treatment of glioblastoma. Conducted at the Hospital das Clínicas of the University of São Paulo Medical School (HCFMUSP) and the Institute of Biomedical Sciences of the University of São Paulo (ICB/USP), the study is led by Professor José Alexandre Marzagão Barbuto. A multidisciplinary team of researchers specializing in neurosurgery, pathology, hematology, and other fields will contribute to a comprehensive approach. The trial aims to determine whether the hybrid DC vaccine can increase overall survival in adult patients with glioblastoma who have completed standard treatment, including surgery, chemotherapy, and radiotherapy. Secondary objectives include evaluating progression-free survival, quality of life, immune response, and the safety of the intervention. The study will enroll 186 patients, who will be randomized into three groups: (1) a control group receiving placebo, (2) a group receiving the DC vaccine, and (3) a group receiving the DC vaccine combined with pembrolizumab.
