Disease Staging of Alzheimer's Disease Using a CSF-Based Biomarker Model

Research Background and Objectives With over 50 million people worldwide affected by cognitive impairment disorders, this number is expected to double by 2050. Alzheimer’s disease (AD) is the most common form of dementia, characterized by extracellular amyloid-beta (Aβ) plaques and intracellular tau protein aggregates in the brain. Over the past tw...

Mapping Medically Relevant RNA Isoform Diversity in the Aged Human Frontal Cortex with Deep Long-Read RNA-Seq

Academic Background RNA isoforms play a critical role in gene expression regulation. On average, human protein-coding genes contain over eight RNA isoforms, leading to nearly four distinct protein-coding sequences. Traditional short-read sequencing technologies, due to their limitations in read length, cannot accurately assemble and quantify RNA is...

Convergent Neuroimaging and Molecular Signatures in Mild Cognitive Impairment and Alzheimer's Disease: A Data-Driven Meta-Analysis with n = 3,118

Convergent Neuroimaging and Molecular Signatures in Mild Cognitive Impairment and Alzheimer's Disease: A Data-Driven Meta-Analysis with n = 3,118

Neuroimaging and Molecular Markers in Alzheimer’s Disease: Data-Driven Meta-Analysis Research Background Alzheimer’s Disease (AD) is a chronic neurodegenerative disease characterized mainly by progressive memory loss and cognitive impairment, making it the most common type of dementia. Neuronal loss, one of the primary hallmarks of AD, is closely a...

Single-Value Brain Activity Scores Reflect Both Severity and Risk Across the Alzheimer’s Continuum

Report on the Association Between Single Value Brain Activity Scores and the Progression of Alzheimer’s Disease Introduction Among the elderly population, cognitive decline and brain structural changes are widespread, even among healthy individuals1-3. Episodic memory, crucial for storing, maintaining, and retrieving single-event memories4, is espe...

Genetics Impact Risk of Alzheimer's Disease through Mechanisms Modulating Structural Brain Morphology in Late Life

In recent years, Alzheimer’s disease (AD) has become a significant health problem affecting the elderly population worldwide. Its related neuropathological changes can begin decades before the appearance of clinical symptoms. To explore more comprehensively the relationship between AD risk and brain morphology, a research team conducted a bidirecti...

Clinical Value of Plasma pTau217 Immunoassay for Assessing Alzheimer's Disease

This research explores the clinical value of plasma phosphorylated tau proteins (p-tau) 217 and 181 in assessing patients with mild cognitive impairment. Mild cognitive impairment may be a precursor stage of Alzheimer’s disease (AD), and early detection and monitoring of disease progression are crucial for disease management. Research Background: A...

Identification of senescent, TREM2-expressing microglia in aging and Alzheimer's disease model mouse brain

Identification of senescent, TREM2-expressing microglia in aging and Alzheimer's disease model mouse brain

Alzheimer’s disease (AD) is an age-related chronic neurodegenerative disorder, whose pathological mechanism involves multiple factors, including brain inflammation. Microglia, particularly those expressing the AD risk gene TREM2, are believed to play a crucial role in the development of AD, but their exact contribution has not been fully elucidated...

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the contribution of the chemical exposome to neurodegenerative disease

Assessing the Risks of Chemical Exposures for Neurodegenerative Diseases Introduction In recent years, many environmental chemicals, from solvents to pesticides, have been implicated in the development and progression of neurodegenerative diseases. However, a systematic approach akin to genome-wide association studies, which have identified dozens ...
