Rationally designed virus-like particles for modulation of chimeric antigen receptor (CAR)-T-cell therapy

摘要

The present invention relates to a modified viral structural protein (VSP) as a tool for specifically targeting a chimeric antigen receptor (CAR) expressed on cells of the immune system. The modified VSPs can assemble into virus like particles (VLP). Exposed areas of the VSPs are modified to comprise in a region located at the surface of a higher order structure, e.g. such as a capsomeric structure, a capsid, a VLP, a viral vector or a virus, a ligand specifically binding to a CAR (LCAR). The present invention thus, provides a modified VSP. The invention also relates to a nucleic acid encoding said VSP. Further, the invention relates to a capsomeric structure, a capsid, a VLP, a viral vector or a virus comprising at least one VSP. Further, the invention relates to a pharmaceutical composition comprising the VSP, the nucleic acid,the capsomeric structure, the capsid, the VLP, the viral vector or the virus comprising at least one VSP. Further, the invention relates to a VSP, a capsomeric structure, a capsid, a VLP, a viral vector or a virus for use in medicine, in particular for use in decreasing or limiting an immune response, treating or preventing tumor lysis syndrome or for treating an immune disease in a patient.
