摘要:
Disclosed is a intranasal spray-type tuberculosis vaccine, which has a high prophylactic effect on human tuberculosis, particularly adult tuberculosis. The nebulizable tuberculosis vaccine for intranasal administration comprises a paramyxovirus gene (particularly rhPIV2) having, integrated therein, a gene encoding an α antigen derived from an acid-fast bacterium (e.g., an α antigen derived from Mycobacterium kansasii or Mycobacterium bovis BCG), an analogue of the gene, or a variant of the gene which has an equivalent function to that of the gene.

The present invention discloses a cell system, as a host cell to be infected with an F gene-deficient virus, which can constitutively and stably express the F protein, and a method for producing an F gene-deficient virus by utilizing the cell. A non-proliferative human parainfluenza type 2 virus vector is produced by co-culturing an F gene-deficient human parainfluenza type 2 virus with a Vero cell having the F gene of human parainfluenza type 2 virus in such a manner that the F gene is non-inducibly expressed, and isolating viral particles from a culture supernatant.
摘要:
Disclosed are: a virus vector in which a gene encoding an antigenic polypeptide is integrated in human parainfluenza virus type 2 gene, wherein the antigenic polypeptide is expressed in the form of a fusion protein with a viral structural protein; and a method for producing the same. The virus vector of the present invention contains a quantitatively large amount of the antigenic peptide on the virus particle and can efficiently deliver the antigenic polypeptide to a target cell.

A cancer test device (1) is provided with: an application unit (40) for applying a staining agent (45), which can selectively stain a product of a cancer-relating gene in a living cell a chromatic color, onto a group of living cells; an imaging unit (10) for imaging the group of living cells having the staining agent (45) applied thereto; and a determination unit (52) for determining the level of malignancy of cancerization of the group of living cells on the basis of the state of the stained expression pattern of the cancer-relating gene in the group of living cells in an image obtained by the aforementioned imaging.
摘要:
The present invention relates to: a virus vector, which can effectively transfer a macromolecular antigenic peptide into target cells while maintaining a three-dimensional structure that is required for functioning as an antigen; and a vaccine utilizing the vector. Specifically, disclosed are: a virus vector, in which a nucleic acid encoding an antigenic polypeptide is integrated immediately 5' upstream of HN gene of an F gene-defective Paramyxoviridae virus gene, wherein the antigenic polypeptide is expressed as a fusion protein of 130 or more amino acid residues, fused with a TM sequence and/or a CT sequence derived from the virus.
