Abstract
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.
