摘要:
The present invention relates to a live avirulent infectious pancreatic necrosis virus which has been shown to be genetically stable in biological studies. Fish exposed to said virus turn out positive for the virus without showing any signs of disease and the avirulent virus has also been shown to protect the fish against IPN for an extended period of time after administration. Thus, a vaccine comprising said virus and said virus for the prophylaxis or treatment of infectious pancreatic necrosis disease are also part of the present invention.
摘要:
The invention relates to therapeutic vaccines for treating neoplasias caused by the human papillomavirus (HPV). The vaccines according to the invention are especially formed by chimeric pseudo-viral capsids of birnavirus containing papillomavirus antigens.
摘要:
Disclosed are processes for producing a vaccine for use against infectious pancreatic necrosis virus (IPNV) in fish, which process comprises culturing a yeast host cell which expresses, and preferably secretes, an IPNV polypeptide, and formulating the polypeptide as a vaccine (preferably by using, or partially purifying) the supernatant. Such vaccines have advantages over vaccines produced in bacteria. Also disclosed are vaccines based VP3 and VP2var proteins, optionally in combination with antigens protective against other fish diseases. The invention further provides related materials (e.g. primers, vectors and host cells) and methods and uses of the vaccines for prophylaxis and therapy.
摘要:
The invention relates to nanocarriers formed by protein assemblies, obtained by means of the assembly of a genetically modified self assembly protein in order to couple products of interest bound to a ligand. These protein nanocarriers can be used as a system for carrying and presenting products of interest.
摘要:
The empty capsids of the infectious bursal disease virus (IBDV), VLP(-VP4), are characterized in that they are constituted only by assembly of IBDV pVP2 proteins and IBDV VP3 proteins. Said capsids have immunogenic activity and can be used in the manufacture of vaccines for protecting animals from the infection caused by IBDV, as well as in the manufacture of gene therapy vectors.

摘要:
There is described a novel virus which is the causative agent of fish pancreatic disease, which is a serious disease affecting Atlantic salmon. A method of isolating the virus through co-cultivation of infected tissues following by passage is described and an isolated strain of the virus has been deposited. The use of the virus, or proteins or polypeptide derived therefrom as a vaccine or in diagnosis is described, together with genetically engineered constructs.
