[Problem to be solved] To provide a transgenic (TG) non-human mammal expressing human matrix metalloproteinase 2 (hMMP2) in whole body tissues, and a model animal developing COPD. [Solution] The objective is solved by development of an hMMP2-expressing TG non-human mammal characterized by the inclusion of a promoter to induce gene expression, and by the expression of the whole hMMP2 gene region placed on the downstream of the promoter that can induce systemic expression of the gene. The promoter for gene expression is preferably abeta-actin promoter, and the non-human mammal is preferably a mouse. Chronic obstructive pulmonary disease (COPD) can be induced by exposing the TG non-human mammal to inhalation of cigarette smoke extract.

The purpose of the present invention is to provide an interepitope sequence that effectively induces antigen presentation of each epitopes in a long-chain peptide antigen having a plurality of epitopes. A vaccine for the purpose contains a long-chain peptide antigen having a plurality of epitopes, said vaccine being characterized in that a sequence between the individual epitopes is one sequence selected from the group consisting of two to ten consecutive tyrosines, two to ten consecutive threonines, two to ten consecutive alanines, two to ten consecutive histidines, two to ten consecutive glutamines and two to ten consecutive asparagines. It is preferred that the vaccine is one selected from the group consisting of an anticancer vaccine, an antibacterial vaccine and an antiviral vaccine. It is also preferred that the vaccine is at least one selected from the group consisting of a peptide vaccine, a DNA vaccine, an mRNA vaccine and a dendritic cell vaccine.

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.

Provide are a method of arranging a large number of living bodies such as cells, embryos, or individuals rapidly, individually, and one by one, a holding sheet for the method, and a device for processing the living bodies. The method of holding living bodies includes using a sheet in which multiple through-holes with a size capable of holding one of the target living bodies but not capable of holding two or more of the living bodies are provided, to thereby arrange and hold the living bodies one by one in the multiple through-holes in the sheet together with a liquid.
