早在2022年,阿斯利康就以3.2亿美元收购TCR-T细胞疗法公司 Neogene Therapeutics。Neogene的TCR疗法是基于 TIL 衍生的 TCR,从通过穿刺活检收集的新鲜冷冻肿瘤组织中分离出来。此次收购标志着阿斯利康收购入局TCR-T 赛道,加速其细胞疗法的开发。 2023年5...
1.1CAR-T/TCR-T/CAR-Treg细胞免疫治疗项目背景 癌症治疗是世界难题,世界重大公共健康问题,人类“头号杀手”。癌症治疗所面临的关键问题:1、早期诊断难:缺乏可靠的肿瘤早期诊断标志物,2、现有的治疗手段遇到瓶颈:手术、放疗、化疗特异性差,副作用大,易复发或转移。因此迫切需要新型的肿瘤治疗手段。免疫疗法的发展彻底...
仅影响CD44highTregsTCRα的克隆多样性(图3B);创伤处理诱导CD44high Tregs细胞群多样性增加,这可能是由于损伤导致其他组织内的CD44highTregs进入淋巴结迁移到创伤部位(图3C,D);通过流式分析创伤处理小鼠Tregs上的TCR-Vβ特异性表达, 同样验证仅CD44highTreg存在显著扩增。
[Eur. J. Immunol. 2011. 41: 31013113.] shed light on the important question of the role of TCR diversity on Treg-cell function by demonstrating that high TCR diversity is crucial for optimal Treg-cell expansion, peripheral reshaping of the Treg-cell TCR repertoire and in vivo suppressive ...
“Participating in the CAR-TCR Summit provides us the opportunity to highlight our advanced CAR Treg optimization approach,” saidFrançois Meyer PhD, Chairman of the Board and Head of Research at TxCell.“Over the past 12 months, we have achieved significant progress in ...

Moreover, T cells that fail to upregulate Foxp3 under iTreg-differentiating conditions and high TCR stimulation acquire the capacity to make TNF and IFN-γ, as well as IL-17 and IL-9, especially if IFN-γ signaling is antagonized. Thus, NF-κB helps T cells control their differentiation ...
缓解期和活动期间Treg细胞TCR CDR3组库对V,J基因取用存在一定程度的偏向性,CDR3组库在插入和缺失核苷酸的数目上有较大的差异.4.SLE患者体内存在显著高频表达的TCR CDR3序列,存在一定数量的保守基序,可能与SLE的发病和活动相关,也可能与SLE体内Treg细胞数量减少和功能受损有关.5.SLE缓解期患者Treg细胞免疫组库和...
