摘要： An objective of the present invention is to provide a safe and effective vaccine therapy for Alzheimer's disease. A minus strand RNA viral vector carrying amyloid gene was constructed, and administered intranasally to 24- to 25-months-old APP transgenic mice. The level of serum anti-A 42 antibody was determined and showed to be markedly higher than the control. The results of histological investigation showed that the administration of a vector of the present invention markedly reduced senile plaques in all of the frontal lobe, parietal lobe, and hippocampus. The brain A level was also markedly reduced. Furthermore, the administration of a vector of the present invention did not result in lymphocyte infiltration in the central nervous system.

摘要： The present invention provides methods for testing and producing (−) strand RNA virus vectors with reduced or eliminated particle formation ability or cytotoxicity. It was revealed that a deficiency in M protein localization in cells introduced with such a (−) strand RNA virus vector could result in the suppression of virus-like particle (VLP) formation in the cells. The present invention provides methods for testing and screening for a (−) strand RNA virus vector in which particle formation ability has been reduced or eliminated, and methods for producing a recombinant (−) strand RNA virus vector in which particle formation ability has been reduced or eliminated. Such a vector, in which VLP formation has been reduced or eliminated, is extremely useful as a vector for gene therapy, since it neither induces cytotoxicity nor immune response due to the secondary release of viruses from cells in which it has been introduced.

摘要： F gene-deficient virus virions are successfully recovered by using an F gene-deficient Sendai virus genomic cDNA. Further, F gene-deficient infectious viral particles are successfully constructed by using F-expressing cells as helper cells. Also, F gene and HN gene-deficient virus virions are successfully recovered by using a virus genomic cDNA deficient in both F gene and HN gene. Further, F gene and HN gene-deficient infectious viral particles are successfully produced by using F- and HN-expressing cells as helper cells. A virus deficient in F gene and HN gene and having F protein is constructed by using F-expressing cells as helper cells. In addition, M gene-deficient infectious virus particles were produced using helper cells expressing M protein. From cells infected with M gene-deficient viruses, release of virus-like particles was inhibited. Further, a VSV-G pseudo type virus is successfully constructed by using VSV-G-expressing cells. Techniques for constructing these deficient viruses contribute to the development of vectors of Paramyxoviridae usable in gene therapy.

摘要： A functional RNP containing negative-strand single-stranded RNA derived from Sendai virus, which has been modified so as not to express at least one envelope protein, has been successfully prepared. An RNP comprising a foreign gene is prepared and inserted into a cell with the use of a cationic liposome, thereby successfully expressing the foreign gene.
