1. An isolated nucleic acid molecule encoding a chimeric antigen receptor (CAR) comprising, from N-terminus to C-terminus:(i) at least one extracellular antigen binding domain comprising a CD33 antigen binding domain encoded by the nucleotide sequence consisting of SEQ ID NO. 1, 3, 5, 7, 9, or 11:
(ii) a transmembrane domain comprising a transmembrane domain of a protein selected from the group consisting of the T-cell receptor (TCR) alpha chain, the TCR betachain, the TCR zeta chain, CD28, CD3 epsilon, CD45, CD4, CD5, CD8, CD9, CD16, CD22, CD33, CD37, CD64, CD80, CD86, CD134, CD137 and CD154, or any combination thereof;
(iii) at least one costimulatory domain comprising a functional signaling domain selected from the group consisting of OX40, CD70, CD27, CD28, CD5, ICAM-1, LFA-1 (CD11a/CD18), ICOS (CD278), DAP10, DAP12, and 4-1BB (CD137), or any combination thereof; and
(iv) an intracellular signaling domain comprising a functional domain selected from the group consisting of a 4-1BB (CD137); CD28, and CD3 zeta signaling domain, or a combination thereof.
