甚至，还可以在体外进行基因改造，把病人或者其他健康人提供的T细胞，改造成能特异性识别neoantigen的“抗癌战士”，回输给病人，这就是比较高级的私人订制的TCR-T或者CAR-T技术，目前国外的大公司正在紧锣密鼓地尝试中。2：个性化肿瘤疫苗 如果能鉴定出一个病人的neoantigen，那么就能在体外合成这些neoantigen所对应的抗...
In the human body, mature T cells are armed with an incredible diversity of T cell receptors (TCRs) that theoretically react to the variety of random mutations generated by tumor cells. The outcomes, however, of current clinical trials using TCR-T cell therapies are not very successful ...

01. The TCR-T cells are constructed and display cytokine secretion and cytotoxicity upon co-culturing with varied tumor cells expressing the KRAS-G12V mutation. Moreover, 1-2C TCR-T cells show anti-tumor activity in preclinical models in female mice. The 9-mer KRAS-G12V mutant peptide ...
除了评估TCR Vβ克隆型的肿瘤特异性外,MANAFEST还可以研究新抗原特异性T细胞应答随时间推移的动态变化,并利用治疗前或治疗后获得的液体活检监测免疫治疗的疗效。此外还有Trogocytososis、T-Scan等新开发的方法用于新抗原的免疫原性。 03 基于新抗原的治疗策略...
注:免疫反应的性质是在这个阶段决定的,关键的平衡代表T效应细胞和T调节细胞的比率是最终结果的关键呈现。 =》第四步和第五步:激活的T细胞开始转移和浸润至肿瘤bed。 =》第六步:特异性地通过其T细胞受体(TCR)与MHCI结合的同源抗原的相互作用重新编码并与癌细胞结合。
(TCR)-transduced T cells, restoring the effector capacity of CD8+T cells by immune checkpoint blockades (ICBs), increasing the immune recognition of tumors with bispecific antibodies (bsAbs) and chimeric antigen receptor (CAR)-transduced T cells, and modulating the tumor immune microenvironment.8...
