Engineering CAR-T cells: Design concepts CAR-T细胞设计的概念 Despite being empirically designed based on a simple understanding of TCR signaling, T cells engineered withchimeric antigen receptors (CARs) have been remarkablysuccessful in treating patients with advanced refractoryB cell malignancies. However, many challenges remainin improving the safety and efficacy of this therapy andextending it toward the treatment of epithelial cancers.Other aspects of TCR signaling beyond those directlyprovided by CD3z and CD28 phosphorylation strongly. influence a T cell’s ability to differentiate and acquire fulleffector functions. Here, we discuss how the principles ofTCR recognition, including spatial constraints, Kon/Koffrates, and synapse formation, along with in-depth analysis of CAR signaling might be applied to develop saferand more effective synthetic tumortargeting receptors. 基于对TCR信号的简单理解,经抗原受体改造的T细胞已经成功地用于晚期B细胞淋巴瘤的治疗中。然而这种治疗方式仍存在多种挑战,包括其治疗的安全,有效性和在实体瘤上的使用。除CD3z和CD28磷酸化,TCR信号传导的其他方面强烈的影响着T细胞的分化和其他的效应功能。在这里,我们将讨论TCR识别的原则,包括空间约束和突触的形成,以及深入分析CAR 信号可能适用于开发更安全、更有效的合成肿瘤靶向受体。
