  • Publication number: 20240131067
    Abstract: Disclosed are methods of eliminating at least one target cell in a subject, comprising administering to the subject an effective amount of a composition comprising a plurality of immune cells, wherein each immune cell of the plurality expresses one or more chimeric ligand receptor(s) (CLR(s)) that each specifically bind to a target ligand on the at least one target cell, wherein specifically binding of the one or more CLR(s) to the target activates the immune cell, and wherein the activated immune cell induces death of the target cell. Exemplary target cells include, but are not limited to, hematopoietic stem cells (HSCs).
