Abstract: The application generally relates to enhanced recombinant nucleic acid constructs comprising a cDNA molecule encoding a full length antigenomic (+) RNA strand of a non-segmented negative-sense single-stranded RNA virus for expressing at least one heterologous polypeptide, protein, antigen, or antigenic fragment thereof. The application more particularly relates to constructs with multiple ATUs localized within a single intergenic region of a virus. The application also relates to the association between a construct with multiple ATUs and BAG plasmid to facilitate the introduction and expression of large inserts.

Abstract: The invention is in the field of prevention or treatment of diseases, in particular infectious diseases, and more particularly in the field of multivalent vaccines. The inventors characterized 5? copy-back DI-RNAs produced by recombinant MV strains, including rMV-based vaccines and wild-type MV (wt-MV). The efficiency of these DI-RNAs productions in different cell types was compared. For the first time 5? copy-back DI-RNAs specific binding to RIG-I, MDA5 and LGP2 was assessed and linked to functional outcome in type-I IFN signalling. The inventors provide a composition of products comprising at least (i) a mixture of particles of a rescued recombinant MV-derived virus encoding at least one antigen (ii) a recombinant and/or purified protein, comprising at least one antigen. Regardless of the presentation of the products, and in particular regardless of whether the products are separated or readily separable or presented as a mixture.

Abstract: The invention relates to a genetically modified infectious measles virus derived from a live-attenuated measles virus strain, in which the gene encoding the viral accessory C protein has been knocked out (MV-deltaC). It concerns in particular the use of said genetically modified infectious MV-deltaC in the treatment of malignant tumour or cancer conditions, and for the preparation of agents or compositions for such treatment.
