The present disclosure belongs to the field of biological detection, and particularly relates to a protein antigen combination for detection of Alzheimer's disease (AD) and application thereof. The specific technical solution is as follows: An antigen combination is provided, wherein the antigen combination at least simultaneously includes the following proteins: DOC2A, LGALS1, KDM4D, and ADARB1. The present disclosure provides several new protein antigens and the combination thereof, which can be used for early-screening detection or diagnosis of AD, and are particularly suitable for risk assessment and prediction prior to the onset of AD. Meanwhile, the protein antigens and the combination thereof can distinguish AD from other types of dementia, and can be further prepared into related reagents or kits according to needs.

The invention relates to methods and compositions for developing basal forebrain cholinergic neurons (BFCNs) from stem cells, and in particular, BFCNs having repaired electrophysiological defects relating to one or more mutations in PSEN2, and to the use of such BFCNs in cell-based therapies to treat Alzheimer's disease.
Resumen de: WO2025166920A1
The present invention belongs to the technical field of detection reagents, and relates to a modified polypeptide and the use thereof. The modified β amyloid protein polypeptide comprises peptide fragment I, peptide fragment II, and peptide fragment III located between the peptide fragment I and the peptide fragment II. The peptide fragment I contains a sequence as shown in SEQ ID NO: 9, the peptide fragment II contains a sequence as shown in SEQ ID NO: 18, and the peptide fragment III is composed of non-hydrophobic amino acids. Linker compounds are added between the peptide fragment I and the peptide fragment III, as well as between the peptide fragment II and the peptide fragment III. Compared with the original polypeptide, the modified polypeptide is reduced in terms of synthesis difficulty and cost, and improved in terms of stability. In terms of reaction activity with antibodies, the modified form is consistent with the original polypeptide, is a better raw material form for a calibrator of a diagnostic reagent, and is beneficial to development and wide application of a detection kit.
Resumen de: US2024197682A1
A method of inhibiting propagation of protein misfolding associated with a neurological disease, is carried out by contacting an environment populated with a propagating amyloid conformation of a protein (prion) associated with a neurological disease with molecules which binds multiple adjacent sites of the protein assemblies and allowing the molecules to bind multiple cites of the protein assemblies; and thereby impeding propagation of the disease-associated conformation of the protein in the environment. Drug/prion complexes are formed and uses of the drugs in detection and treatment of neurodegenerative diseases are disclosed.
