Disclosed herein are chimeric receptors comprising an extracellular domain with affinity and specific for the Fc portion of an immunoglobulin molecule (Ig), an Fc -binding domain; a transmembrane domain; at least one co- stimulatory signaling domain; and a cytoplasmic signaling domain comprising an immunoreceptor tyrosine-based activation motif (ITAM). Also provided herein are nucleic acids encoding such chimeric receptors and immune cells expressing the chimeric receptors. Such immune cells can be used to enhance antibody-dependent cell-mediated cytotoxicity and/or to enhance antibody-based immunotherapy, such as cancer immunotherapy. |
