摘要:
The present invention concerns methods and compositions for the treatment of cancer and cancer cells using altered poxviruses, including a vaccinia virus that has been altered to generate a more effective therapeutic agent. Such poxviruses are engineered to be attenuated or weakened in their ability to affect normal cells. In some embodiments, methods and compositions involve poxviruses that possess mutations that result in poxviruses with diminished or eliminated capability to implement an antiviral response in a host. Poxviruses with these mutations in combination with other mutations can be employed for more effective treatment of cancer.
摘要:
Presented herein is the discovery of a new human picornavirus, Cosavirus (previously termed Dekavirus), methods of detecting the Cosavirus and diagnosing Cosavirus infection, methods of treating or preventing Cosavirus infection, and methods for identifying anti-Cosavirus compounds.
摘要:
The present invention relates to isolated Clostridium perfringens bacteriophage lytic enzymes from baccteriophages CP26F and CP39O, and uses in controlling Clostridium perfringens.
摘要:
Recombinant multivalent non-pathogenic Marek's Disease virus constructs that encode and express both Infectious Laryngotracheitis Virus and Newcastle Disease virus protein antigens, and methods of their use in poultry vaccines.
摘要:
The invention relates to engineered Herpes simplex virus (HSV) particles that are targeted to one or more specific binding pair members, such as receptors. Also, recombinant vectors for producing such HSV particles are provided. By reducing the affinity of HSV for its natural receptor(s) and increasing the affinity for a selected receptor, the HSV particles of the invention are useful for targeting cells that express the selected receptor, which itself may be a product of genetic engineering. The ability to selectively target cells render the HSV particles. particularly useful in selectively diagnosing, treating, and imaging cells bearing the selected binding pair member, such as a receptor. The invention also provides for polynucleotide-based therapy to cells bearing the selected binding pair member such as a receptor.
摘要:
Novel simian adenovirus 41 and two isolates thereof are described. Various uses of these isolates, including construction of a recombinant vector which comprises simian adenovirus 41 sequences and a heterologous gene under the control of regulatory sequences are provided. A cell line which expresses simian adenovirus 41 gene(s) is also disclosed. Methods of using the vectors and cell lines are provided.
摘要:
Disclosed are improved recombinant adeno-associated viral (rAAV) vectors having mutations in one or more capsid proteins. Exemplary vectors are provided that have altered affinity for heparin or heparin sulfate, as well as vectors, expression systems, and rAAV virions that lack functional VP2 protein expression, but are nevertheless, fully virulent. Also provided by the invention are rAAV vector-based compositions, virus particles, host cells, and pharmaceutical formulations that comprise them useful in the expression of selected therapeutic proteins, polypeptides, peptides, antisense oligonucleotides and/or ribozymes in selected mammals, including organs, tissues, and human host cells.
摘要:
Provided are a full genome DNA of a human cytomegalovirus (HCMV) strain JHC isolated from Korean patients and open reading frames (ORFs) thereof and, more particularly, UL1, UL119 and RL6.
摘要:
A process of producing one or more than one protein of interest, comprising: (a) providing a plant or plant cells comprising a first heterologous nucleotide sequence comprising a nucleotide sequence encoding an RNA replicon, and a first inducible promoter operably linked to said nucleotide sequence encoding said RNA replicon; said RNA replicon not encoding a protein providing for cell-to-cell movement of said RNA replicon in said plant; said RNA replicon encoding a polymerase and said one or more than one protein of interest, said polymerase being adapted for replicating said RNA replicon; and (b) inducing, in said plant or plant cells of step (a), said inducible promoter, thereby producing said one or more than one protein of interest in said plant or plant cells.
摘要:
The present invention relates to recombinant cells as well as to methods for the generation of non-segmented negative-sense single-stranded RNA viruses (NNV or mononegavirales) from cloned deoxyribonucleic acid (cDNA), especially from measles virus and in particular from attenuated strains such as those approved for vaccination, in particular from the attenuated Schwarz measles virus and various recombinant Schwarz measles-based viruses expressing heterologous sequences. Such rescued viruses can be used, after amplification, as vaccines for immunization against measles and/or against the heterologous peptides or proteins expressed.
