Patent: 10,246,505

Summary for Patent: 10,246,505

Title:	Chimeric antigen receptors to control HIV infection
Abstract:	The present disclosure is directed to novel multispecific chimeric antigen receptor (CAR) proteins and DNA sequences encoding these proteins. The CARs comprise at least two extracellular domains fused, via a transmembrane domain to a cytoplasmic signaling domain comprising two signaling domains. The disclosure further relates to nucleic acids encoding the novel CARs, to host cells expressing the novel CARs, and to methods of using the CARs to co-stimulate effector functions in the cells and for using cells expressing the receptors for treatment of disease and viral infections. The disclosure also relates to methods of generating a recombinant T cell with reduced susceptibility to HIV infection.
