Methods for generating immune responses using adenovirus vectors that allow multiple vaccinations with the same adenovirus vector and vaccinations in individuals with preexisting immunity to adenovirus are provided.

Provided are compounds of Formula (II) that enhance the efficacy of viruses by increasing spread of the virus in cells, increasing the titer of virus in cells, or increasing the antigen expression from a virus, gene or trans-gene expression from a virus, or virus protein expression in cells. Other uses, compositions and methods of using same are also provided. ##STR00001##

The present application provided defective bovine adenovirus (BAV) vectors that lack pV function. Cell lines and methods of preparing such vectors are provided. In addition, the invention provides methods of treating a disease or disorder with a defective BAV lacking pV function as well as vaccine comprising a defective BAV lacking pV function.

The present invention relates to new adenoviral coat protein based delivery vehicles. They are based on a modified penton base protomers that assemble into VLPs. Exposed areas of the penton base proteins can be modified to allow the VLP to specifically bind to any target and/or to comprise any desired peptide epitope. Additional cargo, e.g. drugs, proteins, or nucleic acids, can reversibly or irreversibly attached to the VLP via engineered fibre protein fragments. The present invention relates to such engineered penton base protomers, engineered proteins comprising an adenovirus fibre protein N-terminal fragment specifically binding to an adenovirus fibre protein binding cleft of a penton base protomer, VLPs comprising the engineered penton base protomers and optionally engineered proteins comprising an adenovirus fibre protein N-terminal fragment specifically binding to an adenovirus fibre protein binding cleft of a penton base protomer, nucleic encoding the engineered proteins, the VLPs as well as methods of producing the proteins and VLPs.

The invention describes new peptides containing epitopes recognized by CD4+ natural killer T (NKT) cells for increasing activity for use in infectious diseases, autoimmune diseases, immune reaction to administration of allofactors, allergic diseases, therapy of tumors, prevention of graft rejection and prevention of immunization against viral proteins used in gene therapy or gene vaccination.

The present invention discloses a combination of vaccine strains for treating, preventing, relieving or controlling Canine Distemper, Canine Parvovirus Enteritis and Canine Infectious Hepatitis, comprising: Canine Distemper virus vaccine strain with the microorganism deposition accession number CGMCC No. 19397, Canine Parvovirus vaccine strain with the microorganism deposition accession number CGMCC No. 19398 and Canine Infectious Hepatitis virus vaccine strain with the microorganism deposition accession number CGMCC No. 19396. The three vaccine strains of the combination of vaccine strains are low in toxicity and good in immunogenicity. The present invention further discloses a live vaccine composition using the above-mentioned combination of vaccine strains as immunogen. The vaccine composition is safe and effective.

The invention provides a gene sequence which can encode and express adenovirus hexon protein in vitro, and is represented as SEQ ID NO: 3. Also invented a protein which was translated and expressed by the gene sequence according to the invention, and the invention also relates to the use of the protein as an antigen to immunize rabbits to obtain a polyclonal antibody. The antibody mentioned above can detect adenovirus with high sensitivity and specificity.

The present invention relates to novel adenovirus strains with an improved seroprevalence. In one aspect, the present invention relates to isolated polypeptides of adenoviral capsid proteins such as hexon, penton and fiber protein and fragments thereof and polynucleotides encoding the same. Also provided is a vector comprising the isolated polynucleotide according to the invention and adenoviruses comprising the isolated polynucleotides or polypeptides according to the invention and a pharmaceutical composition comprising said vector, adenovirus, polypeptide and/or polynucleotide. The invention also relates to the use of the isolated polynucleotides, the isolated polypeptides, the vector, the adenoviruses and/or the pharmaceutical composition for the therapy or prophylaxis of a disease.

Methods and compositions for generating enhanced immune responses using adenovirus vectors that allow for multiple vaccinations in combination with an IL-15 superagonist complex in subjects in need thereof are provided.

The invention relates to a recombinant adenovirus comprising an albumin-binding moiety on the outer surface of the adenoviral hexon protein, pharmaceutical compositions containing it and its medical use. Particularly, the invention relates to an oncolytic adenovirus comprising a sequence encoding an albumin-binding moiety inserted in the hypervariable region 1 (HVR1) of the hexon protein coding sequence and its use in the prevention and/or treatment of cancer.
