摘要:
An altered avian NDV that contains the coding sequence of avian interleukin-4 (IL-4), or a portion thereof, in the reverse orientation suppresses in-ovo IL-4 production via RNAi when administered to embryonic birds. An immunogenic composition containing this altered NDV is included in this invention. The altered avian NDV can, optionally contain a polynucleotide encoding a heterologous antigen from a heterologous avian pathogen and can produce said heterologous antigen in-ovo .

Described herein are chimeric Newcastle disease viruses engineered to express a heterologous interferon antagonist and compositions comprising such viruses. The chimeric Newcastle disease viruses and compositions are useful in the treatment of cancer.
摘要:
The invention relates to a recombinant Mononegavirales virus (MV) vector comprising a foreign gene that is flanked by non-coding regions of a MV virus gene.
摘要:
The goal of the invention is to increase the therapeutical activity of oncolytic NDV. This issue is solved by a Newcastle Disease Virus comprising a recombinant nucleic acid, wherein the nucleic acid codes for a binding protein that has a therapeutic activity when expressed by the virus-infected tumor cell. Binding proteins belong to the following group: A natural ligand or a genetically modified ligand, a recombinant soluble domain of a natural receptor or a modified version of it, a peptide-ligand, an antibody molecule and derivatives thereof or antibody-like molecules like ankyrin repeat molecules or derivatives thereof.
摘要:
The present invention relates to recombinant RNA virus templates derived from and applicable to negative strand naturally non-segmented viruses, including the families Bornaviridae, Filoviridae, and Paramyxoviridae, and methods for generating such recombinant RNA virus templates, wherein the templates are generated from two or more recombinant RNA molecules. The invention relates to the use of segmented recombinant RNA virus templates for naturally non-segmented RNA viruses to express heterologous gene products in appropriate host cell systems and/or to construct recombinant viruses taken from that family and that express, package, and/or present the heterologous gene product. The invention includes the expression products and recombinant and chimeric viruses thus prepared and vaccine and therapeutic formulations comprising the recombinant RNA viruses.
摘要:
The present invention concerns cDNAs for making attenuated, infectious Newcastle disease virus (NDV). Another aspect of the invention relates to methods of making the cDNAs. Another aspect of the invention is a vector containing the cDNA optionally linked to an operable promoter. Within the scope of the invention are vaccines comprising the attenuated, infectious NDV. Also disclosed are methods of making the vaccines and methods of using the vaccines to prevent or treat Newcastle disease in an avian host. The present invention also concerns the nucleotide sequences of the entire genome of NDV, the leading region, the trailing region, and the NP region, as well as proteins encoded by these nucleotide sequences.
摘要:
The present invention encompasses engineered Newcastle Disease Virus (NDV) vaccines or compositions. The vaccine or composition may be a recombinant vaccine. The invention also encompasses recombinant vectors encoding and expressing avian pathogen antigens, more specifically avian influenza proteins, epitopes or immunogens. Such vaccines or compositions can be used to protect animals, in particular avian, against disease.
摘要:
The invention relates to methods of stimulating an immune response against an antigenic protein in a mammalian subject. More specifically, the invention relates to routes of administration of a hybrid Newcastle Disease Virus-vector (NDV-vector) for eliciting an immune response against an antigenic protein that is encoded by the hybrid NDV-vector.
