Car-t cell with good blood-brain barrier permeability, product, and use thereof

Abstract

Disclosed is a CAR-T cell with good blood-brain barrier permeability, a product, and use thereof, relating to the technical field of treatment of central nervous system diseases. Based on the study on CAR-T cell immunotherapy for central nervous system diseases, this disclosure provides a CAR-T cell with good blood-brain barrier permeability and a corresponding drug for treating or improving the central nervous system diseases. The CAR-T cell targets B-cell maturation antigens and highly expresses a chemokine receptor CXCR3 and chemokines CCL1, CCL3, and CCL4. This disclosure further provides a product for detecting and judging the blood-brain barrier permeability of the CAR-T cell, such as probes, reagents, and kits, which can accurately detect and judge the blood-brain barrier permeability of a specific CAR-T cell.
