靶向表面结合肿瘤抗原的表达嵌合抗原受体(CAR)的T细胞已经产生了有希望的临床结果,最近有两种CD 19 CAR-T细胞疗法获得了FDA批准用于治疗B细胞恶性肿瘤。采用汽车识别可溶性配体(生理学和疾病中的一类独特生物标志物)可以显著拓宽汽车在疾病治疗中的用途。在这项研究中,我们证明了CAR-T细胞可以被改造为对不同的可溶性配体(包括CD 19胞外域,GFP变体和转化生长因子β(TGF-β))产生强烈反应。我们还表明,响应于可溶性配体的CAR信号传导依赖于配体介导的CAR二聚化,并且可以通过调节CAR的配体结合和信号传导结构域之间的机械偶联来微调CAR对可溶性配体的响应性。我们的研究结果支持机械转导在CAR信号传导中的作用,并证明了系统地工程化免疫细胞对可溶性细胞外配体的反应的方法。
Chimeric antigen receptor (CAR)-expressing T cells targeting surface-bound tumor antigens have yielded promising clinical outcomes, with two CD19 CAR-T cell therapies recently receiving FDA approval for the treatment of B-cell malignancies. The adoption of CARs for the recognition of soluble ligands, a distinct class of biomarkers in physiology and disease, could significantly broaden the utility of CARs in disease treatment. In this study, we demonstrate that CAR-T cells can be engineered to respond robustly to diverse soluble ligands, including CD19 ectodomain, GFP variants, and transforming growth factor beta (TGF-β). We additionally show that CAR signaling in response to soluble ligands relies on ligand-mediated CAR dimerization, and that CAR responsiveness to soluble ligands can be fine-tuned by adjusting the mechanical coupling between the CAR’s ligand-binding and signaling domains. Our results support a role for mechanotransduction in CAR signaling and demonstrate an approach to systematically engineer immune-cell responses to soluble, extracellular ligands.
