Abstract
The present invention relates to a human CD123-targeting chimeric receptor ligand, comprising an IL-3 molecule-based CD123 binding domain, a transmembrane region, and an intracellular signaling domain. The present invention provides a T cell modified by the human CD123-targeting chimeric receptor ligand and capable of specifically binding with CD123 on tumor cell surfaces, thereby having specific cytotoxicity on tumor cells. The present invention further relates to an application of the human CD123-targeting chimeric receptor ligand and an immune effector cell thereof in preparing an anti-tumor immunotherapy drug.
