Chimeric Antigen Receptor (CAR)-redirected T cells show great efficacy in the patient-specific therapy of hematologic malignancies. Here, we demonstrate that a DARPin with specificity for CD4 specifically redirects and triggers the activation of CAR engineered T cells resulting in the depletion of CD4+ target cells aiming for elimination of the human immunodeficiency virus (HIV) reservoir.

设计锚蛋白重复蛋白 (DARPin) 以将嵌合抗原受体 (CAR) 重定向的 T 细胞靶向 CD4+ T 细胞,以减少潜伏的 HIV+ 细胞库。

嵌合抗原受体 (CAR) 重定向的 T 细胞在血液系统恶性肿瘤的患者特异性治疗中显示出巨大的疗效。在这里,我们证明了对 CD4 具有特异性的 DARPin 特异性重定向和触发 CAR 工程 T 细胞的激活,导致 CD4 +靶细胞的消耗,旨在消除人类免疫缺陷病毒 (HIV) 宿主。
