Abstract
The present disclosure provides use of chemokine receptor CXCR5, wherein CAR-T cells with enhanced chemotaxis are obtained by modifying chimeric antigen receptor T cells (CAR-T cells) utilizing the chemotactic signal between CXCR5 and its ligand CXCL13. The chemokine receptor CXCR5 can guide CAR-T cells to migrate to tumors. It has an excellent ability to enhance the chemotaxis of CAR-T cells, can specifically clear tumor cells, and effectively solve the problem of poor efficacy of the existing CAR-T therapy for solid tumors, thereby exhibiting broad application prospects and great market value.
