摘要
Provided herein are recombinant antigen receptors, for example chimeric antigen receptors (CARs), that comprise modified cytoplasmic domains that provide improved signalling and thereby provide improved performance and safety. Also provided are polynucleotides encoding the recombinant antigen receptors, vectors comprising the polynucleotides, and engineered immune cells comprising the vectors and/or polynucleotides. The invention further provides methods for engineering immune cells to express the recombinant antigen receptors. Improved recombinant antigen receptor signalling is also provided by co-expressing a first recombinant antigen receptor and a second recombinant antigen receptor or co-expressing a recombinant antigen receptor and a protein involved in transducing the signal from the activated recombinant antigen receptor. Also provided are methods of treating a variety of conditions, including, but not limited to, blood cancers and cancers characterized by solid tumors, by administering the engineered cells to patients suffering from such a condition.
