1. A host cell comprising a heterologous polynucleotide encoding a T cell receptor (TCR), wherein the TCR comprises:
(a) a TCR α-chain variable (Vα) domain comprising the CDR1α amino acid sequence set forth in SEQ ID NO:194, the CDR2a amino acid sequence set forth in SEQ ID NO:195, and the CDR3a amino acid sequence set forth in SEQ ID NO:196 or 12; and
(b) a TCR β-chain variable (VB) domain comprising the CDR1β amino acid sequence set forth in SEQ ID NO:197, the CDR2β amino acid sequence set forth in SEQ ID NO:198, and the CDR3β amino acid sequence set forth in SEQ ID NO:199 or 1,
wherein the TCR binds to a VLDFAPPGA (SEQ ID NO:59): human leukocyte antigen (HLA) complex, wherein the HLA comprises HLA-A*201.
