The invention relates to an isolated non-naturally occurring protein comprising the amino acid sequence as set forth in SEQ ID NO: 1, and wherein the amino acid in position 8, 47, 209 and/or 354 is substituted by any amino acid different from the amino acid indicated at that position in said sequence SEQ ID NO: 1.

The invention relates to recombinant VSV viruses and viral vectors which produce a glycoprotein GP of the lymphocyte choriomeningitis virus (LCMV) instead of the G protein of the VSV, to virus producing cells which produce LCMV-GP-pseudotyped VSV virions, and to the use of said vectors and cells in the therapy of solid tumors, especially brain tumors.

The present disclosure is directed to Compositions comprising a population of multivalent viral particles are described herein. Also described herein are immunogenic compositions comprising a population of multivalent viral particles. Additionally, methods of making a multivalent immunogenic composition comprising a population of multivalent viral particles are described. Lastly, methods of using an immunogenic composition to elicit an immune response in a subject are described herein.

The present disclosure provides compositions and methods useful for treating HCMV infection. As described herein, the compositions and methods are based on development of immunogenic compositions that include virus-like particles (VLPs) which comprise one or more Moloney Murine leukemia virus (MMLV) core proteins and include one or more HCMV epitopes, such as, for example, from HCMV envelope glycoproteins gB and/or gH and/or tegument protein pp65. Among other things, the present invention encompasses the recognition that a combination of antigens (e.g., envelope glycoproteins and structural proteins) can lead to beneficial immune responses, for example that include both a humoral response (e.g., production of neutralizing antibodies) and a cellular response (e.g., T-cell activation).

The invention relates to recombinant VSV viruses and viral vectors which produce a glycoprotein GP of the lymphocyte choriomeningitis virus (LCMV) instead of the G protein of the VSV, to virus producing cells which produce LCMV-GP-pseudotyped VSV virions, and to the use of said vectors and cells in the therapy of solid tumors, especially brain tumors.

The present invention relates to the field of oncolytic viruses and in particular to a recombinant rhabdovirus, such as vesicular stomatitis virus encoding in its genome for a CD80 extracellular domain Fc-fusion protein. The invention is further directed to the use of the recombinant virus in the treatment of cancer, and also to methods for producing such viruses.

The invention relates to recombinant VSV viruses and viral vectors which produce a glycoprotein GP of the lymphocyte choriomeningitis virus (LCMV) instead of the G protein of the VSV, to virus producing cells which produce LCMV-GP-pseudotyped VSV virions, and to the use of said vectors and cells in the therapy of solid tumors, especially brain tumors.

The invention relates to an isolated non-naturally occurring protein comprising the amino acid sequence as set forth in SEQ ID NO: 1, and wherein the amino acid in position 8, 47, 209 and/or 354 is substituted by any amino acid different from the amino acid indicated at that position in said sequence SEQ ID NO: 1.

The invention relates to an isolated non-naturally occurring protein comprising the amino acid sequence as set forth in SEQ ID NO: 1, and wherein the amino acid in position 8, 47, 209 and/or 354 is substituted by any amino acid different from the amino acid indicated at that position in said sequence SEQ ID NO: 1.

The present invention relates to the discovery of a high titer hybrid-virus vector that gives rise to high titer virus like vesicles (VLVs) that can be used as a vaccine. The invention includes compositions and methods of generating an evolved hybrid-virus vector vaccine and selecting high titer VLVs, methods of treating and/or preventing or immunizing against, a specific disease or disorder, and methods of inducing a memory T cell and B cell immune response in a subject administered the VLV composition produced thereby. Furthermore, the invention encompasses a pharmaceutical composition for vaccinating a subject as well as a high titer protein expression system.
