The present invention provides a kit of a related marker for a central neurodegenerative disease and a detection method thereof. The kit uses a double antibody sandwich detection method, and can simultaneously detect 5 Alzheimer disease-related proteins in the same sample. An A microsphere labeled with a rabbit antibody is adopted, shaking is conducted in an incubation process, and an incubating agent, including polyol, a polymer, a nonionic surfactant and a chelating agent, is added. The aforementioned components cooperate with each other to achieve a long-term effect of maintaining suspension of the microspheres, so as to promote the reaction in the incubation process, reduce the formation of microsphere agglomeration and reduce non-specific binding. The Fc fragment of a detection antibody is removed, and thus the interference with a non-specific reaction is excluded. The aforementioned improvements improve the accuracy in detection of the relevant proteins of Alzheimer disease, make the clinical detection application be more convenient, can reduce the cost of reagents and labor, and has strong specificity, high sensitivity and good repeatability, and thus has good application prospect.

Some aspects pertain to stimulating a cell to induce a phenotype characteristic of a neurodegenerative disease or disorder and contacting the cell with a potential drug candidate and determining a responsive change, wherein a decrease or loss in the phenotype is indicative that the drug candidate is capable of treating, preventing, reducing or ameliorating neurodegenerative diseases or disorders.
Resumen de: WO2024149703A1
Alzheimer disease (also termed Alzheimer's disease or AD) is a progressive and devastating neurodegenerative disorder with a poor prognosis, and for which no curative treatment is available yet With respect to diagnosis, a huge amount of work has been performed with the aim to identify relevant markers for diagnosing AD, ideally the different stages of progression thereof. It is admitted in the art that development of AD involves both genetic factors and non- genetic factors. This explains why the search for biomarkers includes identification of genetic and non-genetic biomarkers. Further, even though the field of Alzheimer disease research has rapidly developed over the last decade, there is still a lack of disease-modifying therapies. Thus, it remains a great need for methods allowing a diagnosis of the Alzheimer disease. The present disclosure relates to methods relating to the diagnosis of AD, including the development stage of AD, as well as methods for monitoring the efficiency of a (candidate) therapeutic treatment of AD, which methods take benefit from the inventors' findings that AD nucleated cells, especially AD skin fibroblasts, show one or more perinuclear crowns of the auto-phosphorylated form of the ATM protein.
