The present invention provides nucleic acids, vectors, host cells, methods and compositions to confer and/or augment immune responses mediated by cellular immunotherapy, such as by adoptively transferring CD8+ central memory T cells or combinations of central memory T cells with CD4+ T cells that are genetically modified to express a chimeric receptor under the control of an inducible promoter. In some alternatives the genetically modified host cell comprises a nucleic acid comprising a polynucleotide coding for a chimeric antigen receptor comprising a ligand binding domain, a polynucleotide comprising a spacer region, a polynucleotide comprising a transmembrane domain, and a polynucleotide comprising an intracellular signaling domain under the control of a drug inducible promoter. Controlling the expression of the chimeric receptor provides for the ability to turn expression on and off depending on the status of the patient. Pharmaceutical formulations produced by the method, and methods of using the same, are also described.
本发明提供了核酸、载体、宿主细胞、方法和组合物,以赋予和/或增强由细胞免疫疗法介导的免疫应答,例如通过收养性转移CD8+中心记忆T细胞或中心记忆T细胞与CD4+T细胞的组合,这些细胞经过遗传修饰,在可诱导启动子的控制下表达嵌合受体。在某些替代方案中,转基因宿主细胞包括核酸,该核酸包含编码嵌合抗原受体的多核苷酸,嵌合抗原受体包含配体结合域、包含间隔区的多核苷酸、包含跨膜域的多核苷酸和包含细胞内信号传导域的多核苷酸,受药物诱导启动子控制。通过控制嵌合受体的表达,可以根据患者的状态开启或关闭表达。还描述了用该方法生产的药物制剂和使用方法。
