摘要:
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.
摘要:
The invention provides methods for propagating a monkey adenovirus in a cell, including a human cell, comprising one or more gene products isolated from a human adenovirus. Also provided are methods for propagating wherein the monkey adenovirus comprises a nucleic acid sequence encoding a human adenovirus gene product. The invention further provides a monkey adenovirus, including a replication-deficient monkey adenovirus, obtained by such propagation methods.

The present invention provides compositions, compounds, and methods relating to recombinant adenoviral-based polypeptides for treating disorders associated with epithelial tissues.
摘要:
Polypeptides are disclosed comprising, in N-terminal-to-C-terminal order: an N-terminal segment of Ad5 fiber tail sequence; at least 2 pseudorepeats of an Ad5 fiber shaft domain sequence; a portion of a third Ad5 fiber shaft domain sequence; a carboxy-terminal segment of a T4 fibritin bacteriophage trimerization domain sequence; a linker sequence; and a camelid single chain antibody sequence. A camelid single chain antibody sequence can be against a human carcinoembryonic antigen. Also disclosed are nucleic acids encoding these polypeptides, and adenovirus vectors comprising the polypeptides. Methods are disclosed for treating a neoplastic disease. These methods can comprise administering an adenovirus vector comprising a disclosed polypeptide. Also disclosed are methods of targeting a vector to CEA-expressing cells. These methods comprise administering an adenovirus vector comprising a disclosed polypeptide. Methods can further comprise subjecting a subject to ionizing radiation in an amount effective for inducing CEA overexpression.

摘要:
The invention relates to methods for isolating traffic-enhancing mutants of drug delivery proteins. In one embodiment, the invention provides a carrier for delivering a therapeutic agent to an organelle, comprising a polypeptide encoded by a mutant penton base gene. In another embodiment, the invention provides a method of enhancing trafficking to a cell by administering a composition comprising a penton base (PB) protein with one or more mutations that enhance cellular entry.
