Abstract

The present invention provides Claudin-6-specific immunoreceptors (T cell receptors and artificial T cell receptors (chimeric antigen receptors; CARs)) and T cell epitopes which are useful for immunotherapy.

Claims (11)

1 . An artificial T cell receptor comprising:

a binding domain for claudin-6 (CLDN6) comprising the amino acid sequence of SEQ ID NO: 40;

a costimulatory domain selected from the group consisting of: CD28, CD137 (4-1BB), CD134 (OX40), and CD278 (COS); and

a T cell signaling domain that activates cytotoxic lymphocytes upon binding to CLDN6.

2 . The artificial T cell receptor of claim 1 , wherein the costimulatory domain is CD137 (4-1BB).

3 . The artificial T cell receptor of claim 1 , further comprising a transmembrane domain.

4 . The artificial T cell receptor of claim 3 , further comprising a spacer region which links the binding domain for CLDN6 to the transmembrane domain.

5 . The artificial T cell receptor of claim 1 , wherein the T cell signaling domain comprises the endodomain of CD3-zeta or a functional fragment thereof.

6 . The artificial T cell receptor of claim 1 which comprises a signal peptide which directs the nascent protein into the endoplasmic reticulum.

7 . The artificial T cell receptor of claim 6 , which comprises the structure:

NH2-signal peptide-binding domain for CLDN6-spacer region-transmembrane domain-T cell signaling domain-COOH.
