Gut-Induced Alpha-Synuclein and Tau Propagation Initiate Parkinson’s and Alzheimer’s Disease Co-Pathology and Behavior Impairments

Gastrointestinal-Induced Spread of α-Synuclein and Tau Proteins Triggers Comorbid Pathology and Behavioral Impairments in Parkinson’s and Alzheimer’s Diseases Background Parkinson’s Disease (PD) and Alzheimer’s Disease (AD) are two common neurodegenerative disorders, caused by the aggregation of α-synuclein (a-syn) and Tau protein in the brain, res...

Neuronal A2A Receptor Exacerbates Synapse Loss and Memory Deficits in APP/PS1 Mice

A2A Adenosine Receptor Exacerbates Synaptic Loss and Memory Deficits in APP/PS1 Mice Alzheimer’s disease (AD) is a neurodegenerative disorder associated with progressive cognitive decline, characterized by the deposition of extracellular β-amyloid (Aβ) plaques and the accumulation of hyperphosphorylated tau protein in neurons. Some epidemiological ...

Diurnal Characteristics of the Orexin System Genes and Its Effects on Pathology at Early Stage in 3XTg-AD Mice

Study on the Circadian Rhythm of Orexin System Genes and Their Impact on Early Alzheimer’s Disease (AD) Pathology Research Background and Objectives Alzheimer’s Disease (AD) is a chronic degenerative disease of the central nervous system, characterized by senile plaques formed by β-amyloid protein (Aβ) aggregation and neurofibrillary tangles formed...

Probable Novel APP Met671Leu Mutation in a Chinese Han Family with Early-Onset Alzheimer’s Disease

A Study Exploring a New Mutation in Early-Onset Alzheimer’s Disease Alzheimer’s Disease (AD) is a common neurodegenerative disorder, accounting for 60-70% of all dementia cases. In recent years, with global population aging and environmental changes, the incidence of AD has been increasing annually. It is predicted that by 2050, the number of patie...

Aβ-Aggregation-Generated Blue Autofluorescence Illuminates Senile Plaques as Well as Complex Blood and Vascular Pathologies in Alzheimer’s Disease

Blue Autofluorescence Generated by Aβ Aggregation Illuminates Senile Plaques and Complex Blood and Vascular Pathologies in Alzheimer’s Disease Research Background Alzheimer’s disease (AD) is a widespread neurodegenerative disorder globally, with senile plaques being the main pathological hallmark of AD, primarily composed of β-amyloid protein (Aβ)....

Low-dose IL-2 treatment rescues cognitive deficits by repairing the imbalance between Treg and Th17 cells at the middle Alzheimer's disease stage

Low-dose IL-2 treatment rescues cognitive deficits by repairing the imbalance between Treg and Th17 cells at the middle Alzheimer’s disease stage Background Alzheimer’s disease (AD) is an age-related neurodegenerative disorder characterized by neuronal damage, amyloid plaque deposition, and chronic inflammation in the central nervous system (CNS). ...

Microglia Undergo Sex-Dimorphic Transcriptional and Metabolic Rewiring During Aging

The Role of Microglia in Neuroinflammation: Metabolic and Gender Differences in Aging Research Background Aging is a major risk factor for neurodegenerative diseases such as Alzheimer’s Disease (AD) and Parkinson’s Disease. Even healthy aging is accompanied by a decline in cognitive function. Previous research has indicated that microglia undergo s...

Co-registration of MALDI-MSI and histology demonstrates gangliosides co-localize with amyloid beta plaques in Alzheimer’s disease

Co-registration of MALDI-MSI and histology demonstrates gangliosides co-localize with amyloid beta plaques in Alzheimer’s disease

Co-localization of Gangliosides with Amyloid Beta Plaques in Alzheimer’s Disease Detected by MALDI-MSI and Histology Alzheimer’s Disease (AD) is a progressive neurodegenerative disease characterized by cognitive impairment and behavioral changes. Historically, AD research has focused on misfolded proteins, but with advancements in mass spectrometry...

Early and Selective Localization of Tau Filaments to Glutamatergic Subcellular Domains within the Human Anterodorsal Thalamus

Background The main purpose of this study is to investigate the distribution and diffusion patterns of tau protein in the early stages of Alzheimer’s disease, with a particular focus on the vulnerability of calretinin-positive neurons in the anterodorsal thalamic nucleus of the human subcortical region and the accumulation of tau pathology protein ...

Brain vasculature accumulates tau and is spatially related to tau tangle pathology in Alzheimer's disease

Study of Tau Protein Accumulation in Brain Vasculature in Alzheimer’s Disease Background Introduction Alzheimer’s disease is characterized by neurodegeneration, with primary pathological features including amyloid plaques and neurofibrillary tangles (NFTs). These tangles are composed of tau protein, and these pathological changes are closely relate...
