1. An expression vector of an artificial chimeric antigen receptor (CAR), comprising:
a CD 19 antigen-binding fragment sequence comprising a nucleic acid sequence encoding a heavy chain variable domain, a light chain variable domain and a linker,
wherein the nucleic acid sequence of the heavy chain variable domain is SEQ ID NO: 2 and the nucleic acid sequence of the light chain variable domain is SEQ ID NO: 1,
or the nucleic acid sequence of the heavy chain variable domain is SEQ ID NO: 4 and the nucleic acid sequence of the light chain variable domain is SEQ ID NO: 3,
or the nucleic acid sequence of the heavy chain variable domain is SEQ ID NO: 6 and the nucleic acid sequence of the light chain variable domain is SEQ ID NO: 5;
a transmembrane domain sequence comprising a nucleic acid sequence encoding a transmembrane sequence of CD28, IgG1, CD4, CD8a or any combination thereof; and a signaling domain sequence comprising a nucleic acid sequence encoding at least one immunoreceptor tyrosine-based activation motif (ITAM) sequence, at least one co-stimulatory molecule (CM) sequence, or combination thereof.
