DNA methylation patterns in the frontal lobe white matter of multiple system atrophy, Parkinson’s disease, and progressive supranuclear palsy: a cross-comparative investigation

Cross-Comparative Study of DNA Methylation Patterns in the Frontal Lobe White Matter of Multiple System Atrophy, Parkinson’s Disease, and Progressive Supranuclear Palsy Academic Background Multiple System Atrophy (MSA) is a rare neurodegenerative disease characterized by neuronal loss and gliosis, accompanied by glial cytoplasmic inclusions (GCIs) ...

Characterisation of Premature Cell Senescence in Alzheimer’s Disease Using Single Nuclear Transcriptomics

Characterisation of Premature Cell Senescence in Alzheimer’s Disease Using Single Nuclear Transcriptomics

Characteristics of Premature Cellular Senescence in Alzheimer’s Disease: Application of Single-Nucleus Transcriptomics Research Background and Objectives Alzheimer’s disease (AD) is the most common type of dementia in the elderly, characterized by extracellular deposition of β-amyloid protein and intracellular neurofibrillary tangles. Other patholo...

Amyloid-β peptide signature associated with cerebral amyloid angiopathy in familial Alzheimer’s disease with APPdup and Down syndrome

Background Introduction Alzheimer’s disease (AD) is an age-related neurodegenerative disease characterized by the death of neurons in the brain. Its main pathological features include extracellular β-amyloid plaques and intracellular neurofibrillary tangles (NFTs). β-amyloid plaques are primarily composed of aggregated Amyloid beta peptides (Aβ). A...

Sex Differences in the Extent of Acute Axonal Pathologies After Experimental Concussion

Gender Differences in Acute Axonal Pathology Following Experimental Concussion Academic Background Each year, approximately 50 million people worldwide suffer from concussions, also known as mild traumatic brain injuries (TBI). However, for more than 15% of patients, this “mild” brain injury can lead to lasting neurocognitive dysfunction. The exist...

Neuropathologically Directed Profiling of PRNP Somatic and Germline Variants in Sporadic Human Prion Disease

Somatic and Germline PRNP Variants in Sporadic Human Prion Disease: A Neuropathological Study Introduction Prion diseases are a class of infectious, progressive, and fatal neurodegenerative diseases characterized by the pathological folding and aggregation of prion protein (PrP). Prion protein is encoded by the PRNP gene, with normal cellular prion...

Differences in the Cerebral Amyloid Angiopathy Proteome in Alzheimer's Disease and Mild Cognitive Impairment

Differences in the Cerebral Amyloid Angiopathy Proteome in Alzheimer's Disease and Mild Cognitive Impairment

Cerebral amyloid angiopathy (CAA) is a disease caused by the deposition of amyloid-beta (Aβ) in cerebral blood vessels. It is common not only in the elderly and almost all patients with Alzheimer’s disease (AD) but can also occur independently of other AD-related pathologies. The presence and severity of CAA promote the progression of AD-related cl...
