Abstract
The present invention provides a peptide that promotes insulin secretion, and a use for said peptide. A search for insulin secretion promoting factors present in a culture supernatant of brown adipocytes (BA-SUP) derived from human pluripotent stem cells led to the identification of a bioactive peptide that promotes insulin secretion. Through the development of a peptide that imitates said peptide, it was discovered that a short-chain linear peptide capable of forming an α-helix structure exhibits strong insulin secretion promoting activity. Moreover, it was discovered that by heat-treating said peptide under acidic conditions or freeze-drying the peptide after dissolving in a buffer solution, the peptide becomes an active form having an increased insulin secretion promoting effect. Said peptide exhibited an effect of promoting insulin secretion using pancreatic beta cells, and of reducing the blood sugar level in vivo. The peptide group according to the present invention is expected to be applicable to the development of a therapeutic medication for glucose metabolism disorders.

Provided is a technology for more efficient genetic modification, including target gene disruption, using a guide RNA-dependent nuclease. The present invention also addresses the problem of different cleavage efficiencies for each target sequence. Specifically, by the present invention, a new system was developed in which, when developing a target cleavage system that utilizes a guide RNA-dependent nuclease, only the nuclease gene is integrated into a negative-strand RNA viral vector, which has the properties of high infection efficiency and high transgene expression, and, after the viral vector has been introduced into cells in advance and the nuclease has been caused to be expressed, guide RNA is separately supplied to the cells. As a result, an increase in cleavage efficiency and a reduction in recleavage were both successfully achieved, and the efficiency of target gene modification was improved. The present invention is useful as an efficient genetic modification technology, and also has the feature of making it possible to adjust the enhancement and attenuation of genetic modification efficiency by adjusting cleavage efficiency through adjustment of the amount of guide RNA that is introduced.

Abstract
A polypeptide for selectively inducing a target antigen-specific CD8-positive T cell response is provided. Induction of vaccine-derived human immunodeficiency virus (HIV)-specific CD4-positive T cell response can promote HIV infection, so it would be useful to be able to obtain an HIV vaccine antigen that selectively induces an HIV-specific CD8-positive T cell response. In this invention, the amino acid sequence of a target antigen protein is divided into amino sequences of 8-12 residues, and a polypeptide antigen is designed in which these are linked in a sequence different from that of the original amino acid sequence. As a result of experiments on monkeys involving inoculation of vaccines using viral vectors and DNA expressing this antigen, it was shown that it is possible to efficiently and selectively induce an antigen-specific CD8-positive T cell response. This antigen is thought to be useful as a CD8-positive T cell-inducing vaccine antigen with extremely high selectivity.

The present invention addresses the problem of providing an improved negative-strand RNA viral vector enabling transient high expression of a gene carried by the vector, and quick removal of the vector after the expression, and the use thereof. It was found that if a degron is added to a P-protein possessed by a negative-strand RNA viral vector, high-level expression of a gene carried by the vector is transiently induced after introduction of the vector, and thereafter, the vector can be quickly removed in a manner dependent on the degron. In particular, if the degron is added to a temperature-sensitive P-protein, the vector can be removed to a level below the detection limit within two weeks after cells are infected with the vector. Since the present invention is useful for transiently expressing a transcription factor, such as a reprogramming factor or the like, in target cells, and then quickly removing the vector, the present invention is expected to be applied in cell therapy and regenerative medicine.
