1. A method of treating a CD 1a-positive cancer in a subject in need thereof, said method comprising administering to said subject a CD1a-negative allo-tolerant T cell comprising a nucleic acid encoding a chimeric antigen receptor (CAR) comprising:
(i) an extracellular domain comprising a CD 1a targeting-moiety, wherein the CD 1a targeting moiety is an antibody, scFv, Fab, or scFab comprising a VL domain and VH domain,
wherein said VL domain comprises LCDR1, LCDR2 and LCDR3 polypeptides and said VH domain comprises HCDR1, HCDR2 and HCDR3 polypeptides, and LCDR1 consists of QDINKY (SEQ ID NO: 1), LCDR2 consists of YTS, LCDR3 consists of LHYDNLPWT (SEQ ID NO: 3), HCDR1 consists of GYAFSTYT (SEQ ID NO: 4), HCDR2 consists of INPNSAST (SEQ ID NO: 5), and HCDR3 consists of ARGFYTMDY (SEQ ID NO: 6);
(ii) a transmembrane domain; and
(iii) an intracellular signaling domain.
