    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: [Problems to be Solved] The present invention provides methods for producing antibodies and antibody-producing cells.[Means for Solving the Problems] The present invention provides methods for producing antibodies or antibody-producing cells, such methods including the steps of inoculating non-human animals with minus-strand RNA viral vectors carrying nucleic acids which encode foreign polypeptides to be used as antigens, nucleic acids producing the viral vectors, cells into which the vectors or the nucleic acids producing the vectors have been introduced, or lysates of the cells; and collecting the antibodies or antibody-producing cells from the animals. The antibody production can be induced efficiently by the immune activating effect of the minus-strand RNA viral vectors and a high expression of the antigen polypeptides. The antibodies produced by the methods of the present invention can be used in research and development and in the clinical field.
