The invention provides a pFTM3GW recombinant vector as well as a preparation method and application thereof. The pFTM3GW recombinant vector comprises a specific T cell receptor and a lentiviral vectorpFTM3GW, wherein the specific T cell receptor is used for identifying an antigen NY-ESO-1; the specific T cell receptor used for identifying the antigen NY-ESO-1 sequentially comprises an alpha chain, furin, SGSG flexible amino acid, a linker peptide and a beta chain. In the pFTM3GW recombinant vector, the T cell receptor comprising the alpha chain, the furin, the SGSG flexible amino acid, the linker peptide and the beta chain is inserted into the pFTM3GW vector, and all the components have synergistic interaction, so that the alpha chain and the beta chain of the T cell receptor are promotedto form a stable structure and achieve high-efficiency expression, the signal transduction is promoted, the transfection efficiency and a targeted effect are improved, an immunotherapy effect is promoted, and the pFTM3GW recombinant vector is wide in application prospect and market value.
