摘要:
Disclosed are novel methods for combating diseases characterized by deposition of amyloid. The methods generally rely on immunization against amyloidogenic proteins (proteins contributing to formation of amyloid) such as beta amyloid (Aβ). Immunization is preferably effected by administration of analogues of autologous amyloidogenic polypeptides, said analogues being capable of inducing antibody production against the autologous amyloidogenic polypeptides. Especially preferred as an immunogen is autologous Aβ which has been modified by introduction of one single or a few foreign, immunodominant and promiscuous T-cell epitopes while substantially preserving the majority of Aβ's B-cell epitopes. Also disclosed are nucleic acid vaccination against amyloidogenic polypeptides and vaccination using live vaccines as well as methods and means useful for the vaccination. Such methods and means include methods for identification of useful immunogenic analogues of the amyloidogenic proteins, methods for the preparation of analogues and pharmaceutical formulations, as well as nucleic acid fragments, vectors, transformed cells, polypeptides and pharmaceutical formulations.

The present invention relates to novel vaccines against malaria infections, based on recombinant viral vectors, such as alpha viruses, adenoviruses or vaccinia viruses. The recombinant viral-based vaccines can be used to immunize against different Plasmodium infections, such as infections by P. falciparum or P. yoelii. Novel codon-optimized circumsporozoite genes are disclosed. Preferably, replication-defective adenoviruses are used, derived from serotypes that encounter low titers of neutralizing antibodies. The invention, therefore, also relates to the use of different adenoviral serotypes that are administered to elicit a strong immune response, either in single vaccination set-ups or in prime-boost set-ups in which compositions based on different serotypes can be applied.
摘要:
Disclosed are a method and a medium for cultivating the marine dinoflagellate Dinophysis acuminata. The laboratory culture of D. acuminata causing diarrhetic shellfish poisoning, whose cultivation was known difficult, has been first established, thereby contributing to a better understanding of ecophysiology, biology and toxicology of Dinophysis species, as well as the evolution of dinoflagellate plastids.
摘要:
The invention relates to a method of excysting and growing protozoal oocysts by in vitro tissue culture resulting in production of a continuous culture of merozoites. The invention also provides an economical and reliable supply of cultured Eimeria sp. for vaccine production, assays and research. Domesticated avians that have been vaccinated using the provied Eimeria sp. are also provided.
摘要:
The present invention provides isolated bovine Neospora cultures. Also provided are recombinant immunodominant Neospora antigens. The cultures and antigens are used to develop diagnostic assays for the detection of Neospora infections in cattle and other animals. Also provided are pharmaceutical compositions for the treatment and prevention of Neospora infections.
摘要:
Molecular targets are identified in T. cruzi suitable for use in diagnosis of Chagas disease, drug development, and vaccines, including live vaccines.
摘要:
Disclosed are apparatuses and methods for the production of attenuated aseptic parasites in haematophagous insects generally, and production of Plasmodium species sporozoites in Anopheles species mosquitoes specifically; apparatuses and methods for the production of strains of haematophagous insects with desired properties such as hypoallergenicity or hyperinfectivity; methods of producing a parasite strain that is capable of withstanding cyropreservation at temperatures close to freezing; apparatuses and methods for the injection of an attenuated parasite vaccine; production of parasites and haematophagous insects that are free from contamination by unwanted biological agents; apparatuses for the reconstruction of complex parasitic life cycles aseptically to avoid the contamination of the parasite or the insect vector host with unwanted biological agents.
摘要:
The invention relates to membrane vesicles from non-pathogenic amoeba, in particular from the amoeba Dictyostelium discoideum, containing a molecule of therapeutic interest, to a method of preparing such vesicles and to the use of said vesicles as a vehicle for transferring the molecule therapeutic interest to an eukaryotic mammalian cell.
