This disclosure is directed to compositions and methods for utilizing the boundaries of the C-terminal domains of Nucleoprotein from Zaire Ebola virus as highly stable recombinant protein antigens to generate antibodies for diagnosis and treatment of Ebola virus infection.

Cloned filovirus genomic cDNA and methods of using the cDNA are provided. Further provided are noninfectious lipid encapsulated filovirus-based particles.

Aspects of the present disclosure relate compositions comprising polypeptides or polynucleotides encoding such polypeptides that interact with target proteins such as viral spike proteins, and to methods of their use for treatment and prevention of disease, such as viral infections and/or post-viral infection syndromes.

Compounds useful as components of immunogenic compositions for the induction of an immunogenic response in a subject against infection, methods for their use in treatment, and processes for their manufacture are provided herein. The compounds comprise a nucleic acid construct comprising a sequence which encodes an interferon effector.

Provided are an Ebola virus envelope glycoprotein (that is GP protein) codon optimized nucleotide sequence, a human replication deficient recombinant adenovirus capable of expressing the nucleotide sequence, and applications in preparing a vaccine for preventing Ebola virus diseases. The nucleotide sequence takes a replication deficient 5 type adenovirus that is lack of E1 and E3 in a combined mode as a vector. HEK293 cells that integrate adenovirus E1 genes serve as a packaging cell line, and carried protective antigenic genes are codon optimized Zaire type Ebola virus Makona strain envelope glycoprotein genes. After the envelope glycoprotein genes are optimized by codon, the expression level in transfection cells is obviously improved.

The invention relates to vectors comprising two or more homologous nucleotide sequences and methods for generating them. The invention concerns substituting bases in the homologous nucleotide sequences with different bases that do not alter the encoded amino acid sequence. The invention allows for the reduction of intramolecular recombination between homologous nucleotide sequences, in particular in mammalian cells. The invention further relates to nucleotide sequences containing substituted bases.

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 invention is directed to a composition and/or plasmid and/or vector vaccine which encodes four fragments of the GP1 Ebola protein attached to the extracellular domain of the potent immunostimulatory protein CD40 ligand, in the configuration of two compositions and/or vaccines that are mixed together, to respectively increase the levels of antibodies and CD8 effector T cells, against the lethal Ebola virus.

The disclosure provides a composition comprising immunoglobulin from an equine that has been hyper-immunized with a filovirus immunogen. The disclosure further provides methods of making such compositions and methods of using such compositions, e.g., for treating Ebola virus infection.

The present embodiments provide methods and compositions for pseudotyping viral vectors. Also provided are methods and compositions for creating targeting moiety fused viral glycoproteins. Also provided herein are methods of treating a disease in a subject in need thereof using the compositions provided for herein. Also provided are methods of delivering a molecule of interest to a target cell using the compositions provided for herein.
