Resumen de: WO2025231348A1
Provided are methods of phospho-tau aggregation-based biomarker discovery, and new utilities for discovered biomarkers in Alzheimer's disease (AD) diagnosis, differentiation, treatment, and identification of the presence of pretangles in a subject. Novel p-tau sites, p-tau198, p-tauS356, p-tau396, and p-tau422, identified through such methods showed comparable or superior characteristics with established p-tau biomarkers, and identified biomarkers were capable of differentiating AD or mild cognitive impairment (MCI) from cognitively normal controls.

Resumen de: US2025340593A1
Inventors have shown evidence of VEGF accumulation in extracellular Aβ plaques in the post-mortem brain of patients with Alzheimer's disease (AD) and of the APP/PS1 mouse model of AD. They identified specific binding domains involved in the direct interaction between A0o and VEGF and engineered a peptide that blocks this interaction. The designed peptide binds to Aβ oligomers with high affinity and inhibits the process of Aβ self-aggregation, leading to the blockade of fibrillar aggregation. Furthermore, the peptide prevents soluble Aβ-derived toxins to target synapses in hippocampal neuron cultures and restores long-term potentiation in the hippocampus of the APP/PS1 mouse model of Alzheimer's disease. Thus, these findings have broad implications for preventing and treating diseases with Aβ neurotoxicity such as Alzheimer's disease. Accordingly, the invention relates to a peptide comprising the amino acid sequence KRKKSRYKSWSVYVG (SEQ ID NO: 1).

Resumen de: WO2025223573A1
Provided in the present invention is the use of an Achyranthes bidentata polypeptide combined with a human umbilical cord mesenchymal stem cell-derived exosome in the preparation of a drug for preventing and/or treating Parkinson's disease. A Parkinson's disease (PD) model mouse is established using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), and then an Achyranthes bidentata polypeptide is used in combination with a human umbilical cord mesenchymal stem cell-derived exosome to treat the mouse. It is found that the treatment can significantly relieve PD-related symptoms, for example, restoring the number of dopaminergic neurons in the substantia nigra, improving the expression of tyrosine hydroxylase in the midbrain, relieving motor and olfactory dysfunction of the PD model mouse, reducing the activation of microglia and astrocytes in the olfactory bulb and midbrain, and improving the activity of neurons in the olfactory bulb.
