The present invention relates to a preparation comprising Epstein-Barr virus-like particles (EB-VLPs), said EB-VLPs being essentially free of Epstein Barr virus (EBV) DNA, wherein said EB-VLPs comprise a vaccination polypeptide comprising at least one peptide of an EBV tegument polypeptide and at least one immunogenic peptide; and to polynucleotides, host cells, and methods related thereto.

Epstein-Barr virus-like particles with broadened antigenic spectrum

The present invention relates to a composition comprising Epstein-Barr Virus (EBV) particles for use in vaccination of a subject, wherein said EBV particles comprise a significantly reduced chromosome instability-inducing EBV polypeptide activity. The present invention also relates to a composition comprising EBV particles for use in vaccination of a subject, wherein said vaccination comprises avoiding contacting the cytosol and/or nucleus of cells of said subject with a chromosome instability-inducing EBV polypeptide activity. Moreover, the present invention relates to polynucleotides, host cells, methods, and uses related to the aforesaid compositions.

EBV vaccine

The present invention relates to a polypeptide comprising a) a binding peptide binding to at least one protein selected from the group consisting of CD22, CD19, CD20, and CD21, and b) an immunogenic peptide comprising at least one T-cell epitope for use in vaccination of a subject against B-cell hyperproliferation or for use in the modulation of the immune response in a subject. The present invention further relates to a polynucleotide and a vector encoding said polypeptide and a host cell comprising the same. It also relates to a method for the stimulation of antigen-specific T-cells, comprising a) contacting antigen presenting cells (APC) with a polypeptide, the polynucleotide, or the vector of the invention, b) contacting said APC with T-cells, and c) thereby stimulating antigen-specific T-cells specific for said at least one T-cell epitope; to a method for immunizing a subject against B-cell hyperproliferation, to a method for immunizing a subject against an infectious agent, and to a method for inducing tolerance in a subject.

B-cell receptor complex binding proteins containing T-cell epitopes

The present invention relates to an Epstein-Barr virus-like particle (EB-VLP) substantially free of Epstein-Barr Virus (EBV) DNA. The present invention also relates to a polynucleotide comprising an EBV genome a) lacking at least one expressible gene selected from the group consisting of the BFLF1 gene, the BBRF gene, the BGRF1 gene, the BDRF1 gene, the BALF3 gene, the BFRF1A gene, and the BFRF1 gene, and b) producing the EB-VLP of the invention in a suitable host cell. The present invention further relates to a vector and a host cell comprising the polynucleotide of the invention as well to a method of manufacturing the EB-VLPs, a method of manufacturing a vaccine thereof, a vaccine and a composition comprising the EB-VLPs.

Second generation virus-like particles (VLP) from Epstein-Barr viruses for vaccination purposes

The present invention discloses an ex vivo method for producing a preparation containing CD4+ T cells specific for EBV structural antigens for use in the prophylaxis and treatment of patients with a reduced T cell activity in order to prevent or treat growth of EBV infected B cells.
