Multi-target chimeric antigen receptor

Abstract

Disclosed in the present invention is a multi-target chimeric antigen receptor. Provided in the present invention is a multi-target chimeric antigen receptor consisting of a main peptide chain and an auxiliary peptide chain; the main peptide chain comprises an antigen binding domain A, an auxiliary peptide chain connecting domain B, a transmembrane domain C and an intracellular signaling domain D; the auxiliary peptide chain comprises a main peptide chain connecting domain F; the antigen binding domain A is a polypeptide having an antigen-binding function; the auxiliary chain connecting domain B and the main peptide connecting domain F are combined with each other; the transmembrane domain C is a transmembrane domain of any membrane-binding protein or a transmembrane protein; and the intracellular signaling domain D comprises a primary signaling region. The multi-target chimeric antigen receptor of the present invention can bind to different antigens through the two antigen binding domains thereof, and mediates specific cell killing; and a cytokine and cytokine receptor complex playing the role of a cytokine are introduced into the multi-target chimeric antigen receptor of the present invention.
