1. An isolated polynucleotide encoding a polypeptide comprising an anti-CD19 chimeric antigen receptor (CAR) that comprises the amino acid sequence of SEQ ID NO: 9, wherein the polypeptide does not comprise a rituximab binding site, wherein the polynucleotide comprises a nucleic acid sequence having at least 90% identity to SEQ ID NO: 3 and a short EF1a promoter that is capable of expressing the anti-CD19 chimeric antigen receptor (CAR) in a mammalian T cell, and wherein the short EF1a promoter comprises the nucleic acid sequence of SEQ ID NO:16 and does not comprise the nucleic acid sequence of SEQ ID NO:39.
