针对CD39的免疫治疗策略正在临床试验中,如单克隆抗体TXX-030和CD39阻断抗体IPH520,显示出潜力提升抗肿瘤治疗效果。通过与免疫检查点抑制剂(ICI)如PD-1/PD-L1抑制剂的联合使用,或通过CAR-T疗法改造T细胞,CD39靶向可能成为免疫疗法的重要补充。尽管免疫治疗的进步,如ICI,仍有部分患者对治疗反应有限...
We found that both CD39+ HBVs-CAR-T and CD39+ personalized tumor-reactive CD8+ T cells induced much more apoptosis in HCC organoids. Although the exhaustion status of CAR-T cells increased in CD39+ CAR-T cells, triple knockdown of PD-1, Tim-3, and Lag-3 with shRNAs further enhanced...
与CD19CAR-T细胞相比,研究人员还观察到单个CD19/20/22CAR-T细胞连续杀死靶细胞的频率更高,杀死的靶细胞总数更高,并且无效杀伤率也明显更低。 目前,国内正在招募一款针对B细胞急性淋巴细胞白血病的CAR-T临床试验,这是一款靶向CD19...
Chimeric antigen receptor (CAR)-T cells directed to solid tumors have been less effective, due in part to the low or lost expression of specific tumor antigens. Herein, we developed a different strategy to enhance CAR-T cell persistence and efficacy by producing a multispecific CAR-T or vacci...
LUCAR-G39P细胞制剂是南京传奇生物科技有限公司利用自主研发的同种异体非基因编辑LUCAR平台开发的创新型CD19/CD20 双靶点通用型细胞制剂。这是通过非基因编辑的方式研制的CAR-T免疫细胞制剂,避免了利用基因编辑改造的CAR-T可能引发的宿主免疫排斥反应,同时还能减少CAR-T疗法的生产步骤。
We inserted the antibody sequence into the chimeric antigen receptor (CAR) construct to induce MSLN CAR-T cells to secret the CD39 antibody, and the efficacy was measured in xenograft models of ovarian cancer. Results: We screened human CD39 antibodies using a VHH library and developed a ...
刘东方团队开发的CD147 CAR-NK前期已在肝癌模型中展现出一定的抗肿瘤潜力(Nature Communications,2020),体内外研究中均能有效抑制肿瘤进展,且耐受性良好,但其系统性毒性尤其是神经毒性尚未明确。 本项研究中,研究团队构建了hCD147TG免疫缺...
15.图1显示了抗cd39单克隆抗体mab21和mab23对atp介导的t细胞增殖抑制的阻断。migg2a被用作同种型对照抗体。 16.图2显示了抗cd39嵌合抗体c14、c19、c21和c23对atp介导的t细胞增殖抑制的阻断。higg4是指人类igg4同种型对照抗体。 17.图3显示了树突细胞(dc)上的cd39表达水平。
Recently, it has been found that an antibody neutralizing IL-27 reduces CD39 expression on human monocytes and this may be the main cause of increased frequency of IL17+ T cell proliferation following blockade of IL-27 [82]. The CD39 expression levels are also linked to the cardiovascular ...
论文通讯作者、德国埃尔朗根-纽伦堡大学的Georg Schett博士说,“严重的[红斑狼疮]对CAR-T细胞治疗非常敏感,[患者]可以进入长期的无药物缓解期。” 他说,这项新研究中的副作用是温和的。在癌症研究中,这种类型的疗法已引起了高烧和寒战,呼吸困难,以及细胞因子释放综合征。当CAR-T细胞增殖和释放大量的炎症性细胞因子到...
