The present invention provides a method for detecting onset of, or the risk of development of, a protein misfolding disease, and a method for predicting the age of onset of a protein misfolding disease using nerve cells derived from iPS cells. The present invention also provides a kit to be used in these methods.
摘要:
The present invention provides a method of measuring the activity of neprilysin, etc. More specifically, the present invention provides a method of measuring the activity of neprilysin in nerve cells; a method of screening a protein, a peptide or a compound enhancing the activity or expression of neprilysin in nerve cells by measuring the activity of neprilysin; a method of enhancing the activity or expression of neprilysin; and so on. Thus, the compound enhancing the activity and/or expression of neprilysin, which is obtained by the screening method characterized by using the method of measuring the activity of neprilysin in accordance with the present invention, is useful as a preventive and/or therapeutic agent for Alzheimer's disease. The method of measuring the activity of the present invention can be used for presymptomatic diagnosis of Alzheimer's disease.

摘要:
The present invention provides a non-human model mammal of Alzheimer's disease (AD) containing chimeric amyloid precursor protein (APP) gene capable of producing human amyloid β peptide (Aβ) or a living part thereof, characterized in that Aβ42/Aβ40 ratio at 8-weeks-old is about 7-fold or more (about 140-fold or more in homozygote) higher compared to that of a corresponding wild-type mammal. Moreover, the present invention provides the mammal or a living part thereof, further characterized in that the level of APP expression is not significantly different compared to the corresponding wild-type mammal, and a screening method for a prophylactic and/or therapeutic drug for AD, a biomarker in biological fluids and molecular imaging of amyloid deposition or other pathological changes in the brain for an early diagnosis of AD using the mammal or a living part thereof.
摘要:
AβN3pE-42 is a β amyloid protein that accumulates specifically as a major constituent of senile plaque in the brains of both sporadic and familial Alzheimer's disease patients. The invention provides antibodies that specifically recognize AβN3pE-42 and can be expected to have a strong β amyloid-removing action. Particularly, humanized antibodies against AβN3pE-42 are useful to treat human neurodegenerative diseases. Further, since AβN3pE-42 is localized in the brain, the antibodies of the invention can avoid side effects such as kidney disorders caused by the formation of antigen-antibody complex in the blood. An agent for gene therapy using a vector in which a cDNA encoding a protein comprises the antigen-binding region of the antibody can be an efficient therapeutic drug for removing β amyloid from the brain.
