Abstract: The present invention provides a chimeric antigen receptor (CAR) comprising an extracellular target-binding domain comprising at least one glucose-regulated-protein 78 (GRP78)-binding moiety. The present invention further provides polynucleotides and recombinant vectors encoding such CARs. The present invention further provides isolated host cells and methods for preparing isolated host cells expressing the CARs. The present invention further provides pharmaceutical compositions comprising the host cells and methods for treating a tumor using the pharmaceutical compositions.

Abstract: The present disclosure provides chimeric antigen receptors (CARs), particularly CARs that have enhanced antitumor properties and/or can be regulated by safety switches. Also provided are polypeptides of the CARs and other related molecules, polynucleotides, vectors, and cell compositions comprising the same. Pharmaceutical compositions comprising the polypeptides, polynucleotides, vectors, or cells of the present disclosure, and their uses in treating a cancer in a subject are also provided.

Abstract: Embodiments concern methods and/or compositions related to immunotherapy for cancer. In particular embodiments, engager immune cells harbor a vector that encodes a secretable engager molecule. In particular cases, the engager molecule has an activation domain and an antigen recognition domain. In some embodiments, the engager molecules further comprise a cytokine or co-stimulatory domain, for example.
