An isolated chimeric antigen receptor (CAR) polypeptide, wherein the CAR includes an extracellular antigen-binding domain, including an antibody or antibody fragment that binds to a protein encoded by a herpes virus, or to a protein complex including the protein (herpes virus antigen), wherein the herpes virus antigen is present on the surface of a human cell that is latently infected with said herpes virus and supports the lytic phase of viral replication. The invention further relates to a nucleic acid molecule encoding the CAR of the invention, a genetically modified immune cell, preferably a T cell, expressing the CAR of the invention and the use of the cell in the treatment of a medical disorder associated with human herpesvirus, such as herpes virus-associated cancers, chronic active herpes virus infections or primary herpes virus infections. In preferred embodiments the herpes virus is Epstein-Barr virus (EBV) and a preferred herpes virus antigen target of the CAR is the EBV glycoprotein 350/220 (gp350/gp220).

Chimeric antigen receptor and CAR-T cells that bind a herpes virus antigen

The present invention relates to cells engineered to express at least one cytokine and at least one antigen which induces the self differentiation of dendritic cell (DC) progenitor cells into functional antigen-presenting induced DC (iDC). Moreover, therapeutic uses of said iDC for regenerating the immune system after transplantation of hematopoietic stem cells are disclosed. Said iDC are also useful for generating mice with a functional endogenously regenerated humanized immune system producing antigen-specific T and B cell responses which can be used as animal models for the study of the human adaptive immune responses.
