| abstract |
Provided herein are engineered immune cells, e.g. T cells, expressing a chimeric receptor comprising an intracellular region comprising a CD3zeta (CD3ΞΆ) signaling domain. In some embodiments, the engineered immune cells contain a modified CD247 locus that encodes the chimeric receptor or a portion thereof. In some embodiments, at least a portion of a CD3zeta chain encoded by CD247 genomic locus. Also provided are cell compositions containing the engineered immune cells, nucleic acids for engineering cells, and methods, kits and articles of manufacture for producing the engineered cells, such as by targeting a transgene encoding a portion of a chimeric receptor for integration into a region of a CD247 genomic locus. In some embodiments, the engineered cells, e.g. T cells, can be used in connection with cell therapy, including in connection with cancer immunotherapy comprising adoptive transfer of the engineered cells. |
