The present invention relates to the field of
immunotherapy, in particular to diseases associated with Epstein-
Barr virus (EBV, also known as human gamma herpesvirus 4), such as
cancer or post-transplant lymphoproliferative
disease, in particular to adoptive
T cell therapy or
T cell receptor (TCR)
gene therapy. The present invention provides a combination of nucleic acids encoding at least two TCR constructs or corresponding proteins or host cells, wherein each TCR construct is capable of specifically binding to its respective
epitope in the context of a respective MHC I, and wherein the epitopes are derived from different antigens expressed by the same
infectious agent or
cancer, such as EBV antigens. The present invention further 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 complexed with human MHC I, wherein the
epitope is an epitope of an Epstein-
Barr virus protein, the TCR construct being specific for an epitope from LMP2A, LMP1 or EBNA3C. Proteins encoded by said nucleic acids, corresponding host cells, as well as pharmaceutical compositions and kits are also an object of the present invention.
