The present disclosure provides compositions, methods, kits, and platforms for selectively activating and deactivating chimeric receptor effector cells using humanized chimeric receptor effector cell switches that comprise a humanized targeting moiety that binds CD19 on a target cell and a chimeric receptor interacting domain that binds to a chimeric receptor effector cell and / or chimeric receptor effector cell switches comprising optimized chimeric receptor interacting domains. Also disclosed are methods of treating disease and conditions with such chimeric receptor effector cells and chimeric receptor effector cell switches. 本公开提供了用于使用人源化嵌合受体效应细胞开关选择性地使嵌合受体效应细胞活化和灭活的组合物、方法、试剂盒和平台，所述人源化嵌合受体效应细胞开关包括：人源化靶向部分，其结合靶细胞上的CD19；以及嵌合受体相互作用结构域，其与包括经过优化的嵌合受体相互作用结构域的嵌合受体效应细胞和/或嵌合受体效应细胞开关结合。还公开了用这种嵌合受体效应细胞和嵌合受体效应细胞开关治疗疾病和病状的方法。
