The invention provides a fusion chimeric antigen receptor targeting CA9, a recombinant expression vector and application thereof, and belongs to the technical field of gene engineering. The invention relates to a fusion chimeric antigen receptor for expressing CA9 surface antigen cells in a targeted manner, secreting IL-15SA fusion protein or IL-36gamma and CXCL11 and expressing CCR8 or CXCR6 on a membrane, which comprises a CD8 alpha signal peptide, CA9-targeted scFv, Strep II tag protein, a CD8 alpha hinge domain, a CD28 transmembrane structural domain, a CD28 intracellular signal structural domain, a 41-BB costimulatory domain, a CD3 zeta signal transduction domain and a structural domain for secreting IL-15SA, IL-36gamma or CXCL11 fusion protein, and the membrane expresses a structural domain of CCR8 or CXCR6. The fusion chimeric antigen receptor is expressed in T cells, immune cell infiltration is enhanced, more immune cells are collected, and a better tumor inhibition effect is achieved ...
