The invention relates to a diagnosis and therapeutic preparation for senile dementia and an application thereof, in particular to an application of ARHGAP11A gene, SPAG7 gene and C16ORF7 gene in preparing a diagnosis and therapeutic preparation for senile dementia. In order to solve the problem that molecular markers of senile dementia are scarce at present, the inventors carried out the high-throughput sequencing on peripheral blood samples of patients with senile dementia and healthy people, selected candidate genes, and confirmed that there was a good correlation between the candidate genes and senile dementia through molecular cell experiments, which laid a foundation for clinical gene diagnosis of senile dementia.

Disclosed are the use of neuregulin proteins in preparing a medicine for preventing, treating or delaying preserved ejection fraction cardiac failure in mammals, and a method for using the medicine. Also provided in the present invention is a method for preventing, treating or delaying preserved ejection fraction cardiac failure in mammals, comprising using the medication containing the neuregulin proteins in a special population having the disease or being at risk of having the disease.

Provided is an invention that is based on the novel function of a transcription factor RP58 in cells of the central nervous system. The present invention relates to: a transgenic non-human animal capable of increasing or decreasing the expression of the transcription factor RP58 in cells of the central nervous system of a non-human animal in the nascent stage and/or during and after the developmental stage; and a pharmaceutical composition for use in the treatment or prevention of brain dysfunction, or behavioral disorder, or a disease related thereto, wherein the pharmaceutical composition comprises a transcription factor RP58 protein, or a gene encoding the transcription factor RP58; etc.

The present invention provides a medicine containing a Toll-like receptor agonist, LAG-3 protein, a variant or derivative thereof.

The present invention provides a medicine containing a Toll-like receptor agonist, LAG-3 protein, a variant or derivative thereof.

An object of the present invention is to identify cancer antigen proteins specifically expressed on the surface of cancer cells and to provide a use of antibodies targeting such proteins as therapeutic and/or preventive agents for cancer. The present invention relates to, for example, a pharmaceutical composition for treatment and/or prevention of a cancer, which comprises, as an active ingredient, an antibody or fragment thereof having an immunological reactivity with an MCEMP1 protein having an amino acid sequence shown in any one of the even numbered SEQ ID NOS: 2 to 8 or an amino acid sequence having 80% or more sequence identity with the amino acid sequence, or with a fragment of the MCEMP1 protein comprising 7 or more consecutive amino acids.

Based on the identification of IL-33 as an exacerbating factor in endometriosis and adenomyosis uteri, a therapeutic agent for endometriosis and adenomyosis uteri has an IL-33 antagonist, which is capable of inhibiting the function of IL-33. The IL-33 antagonist is useful for treating, preventing or alleviating endometriosis and uterine adenomyosis uteri.

Disclosed are P. gingivalis antibodies raised against a chimeric or fusion protein, wherein the chimeric or fusion protein comprises a first peptide joined directly or through a linker to a second peptide or polypeptide, wherein (A) the first peptide comprises a region of a P. gingivalis trypsin-like enzyme and (B) the second peptide or polypeptide comprises an adhesin domain of P. gingivalis.
