The present invention relates to the filed of immunotherapy, in particular, of Epstein-Barr virus-associated diseases (EBV, also designated Human gammaherpesvirus 4), e.g., cancer or post-transplant lymphoproliferative disease, in particular, to adoptive T cell therapy or T cell receptor (TCR) gene therapy. The invention provides a combination of nucleic acids encoding at least two TCR constructs, or the respective proteins or host cells, wherein each TCR construct is capable of specifically binding to its respective epitope in the context of the respective MHC I, and wherein the epitopes are peptides from different antigens expressed by the same infective agent or cancer, e.g., EBV antigens. The invention also provides specific nucleic acids encoding a TCR alpha chain construct (TRA) and/or a TCR beta chain construct (TRB) of a TCR construct specific for an epitope in complex with a human MHC I, wherein the epitope is an epitope of an Epstein-Barr-virus protein, wherein the TCR constructs are specific for epitopes from LMP2A, LMP1 or EBNA3C. Proteins encoded by said nucleic acids, corresponding host cells and pharmaceutical compositions and kits are also objects of the invention.
A nucleic acid encoding a TCR alpha chain construct (TRA) and a TCR beta chain construct (TRB) of a TCR construct specific for an epitope in complex with a human MHC I, wherein the epitope is an epitope of an Epstein-Barr-virus (EBV) protein, wherein the epitope has the sequence of SEQ ID NO:
A nucleic acid encoding a TCR alpha chain construct (TRA) and a TCR beta chain construct (TRB) of a TCR construct specific for an epitope in complex with a human MHC I, wherein the epitope is an epitope of an Epstein-Barr-virus (EBV) protein,
A nucleic acid encoding a TCR alpha chain construct (TRA) and a TCR beta chain construct (TRB) of a TCR construct specific for an epitope in complex with a human MHC I, wherein the epitope is an epitope of an Epstein-Barr-virus (EBV) protein,
