Dysregulated TIE‐2 expression is associated with blood‐brain barrier leakiness and Alzheimer's disease‐related neuropathology

Brain Pathology, EarlyView.
Ince et al., have analysed TIE‐1 and ‐2 expression in human brain tissue, including microvessel‐enriched fractions (MVF) and covering a spectrum of AD‐associated pathology, and in CSF from independent cohorts spanning a clinical spectrum from normal cognition to AD.

CRYAB is compromised in pathologically affected oligodendrocytes in multiple system atrophy

Brain Pathology, EarlyView.
CRYAB is hypermethylated and colocalizes with α‐synuclein in multiple system atrophy oligodendrocytes.

Distinctly altered TRPC3 and TRPC6 expression patterns in human Alzheimer's disease cortex and hippocampus

Brain Pathology, EarlyView.
Divergent remodeling of TRPC channels occurs in Alzheimer's disease, with TRPC3 increased in neurons and reactive astrocytes and TRPC6 reduced in pyramidal neurons. These alterations may contribute to calcium dysregulation, neuroinflammation, and synaptic dysfunction during AD progression.

Lewy bodies are surrounded by granulovacuolar degeneration bodies in dementia with Lewy bodies

Brain Pathology, EarlyView.
Here, we report Lewy bodies (LBs) to be enriched for tau‐laden granulovacuolar degeneration bodies (GVBs), suggesting a potential mechanistic interface between α‐synuclein and tau pathology in dementia with Lewy bodies (DLB). Abstract Lewy bodies (LBs), composed primarily of aggregated α‐synuclein (α‐syn), are the pathological hallmark of Lewy body ...

Clinicopathological and molecular heterogeneity of amyloid‐β in unnatural deaths under 70 years: A forensic autopsy–based study

Brain Pathology, EarlyView.
This study investigates amyloid‐beta (Aβ) pathology in a forensic autopsy cohort of relatively young individuals (40–69 years). Using detailed immunohistochemical analyses of multiple Aβ species, we demonstrate marked regional and molecular heterogeneity, particularly within the striatum.

Artificial intelligence–based 3D segmentation of tangle‐associated TDP‐43 in neurodegeneration

Brain Pathology, EarlyView.
Multiplex immunostaining of anti‐phosphorylated TDP‐43, tau (AT8, pS396, TauC3, MN423, GT38), and Thioflavin S combined with AI‐based object recognition, reconstruction, and TAT maturation analysis pipeline in limbic regions revealed that distinct aggregation and tangle maturation patterns underscored region‐specific dynamics in the neurodegenerative ...

α‐Synuclein strain homogeneity in multiple system atrophy subtypes

Brain Pathology, EarlyView.
Two different subtypes of multiple system atrophy are recognized: MSA‐C and MSA‐P. In this manuscript, Lau et al. investigate whether MSA‐C and MSA‐P are caused by different strains of α‐synuclein aggregates. By performing conformational fingerprinting experiments as well as in vitro and in vivo seeding assays, their findings suggest that both MSA‐C ...

Olfactory proteomics reveals the capacity of the HDAC1 inhibitor pyroxamide to halt the α‐synuclein preformed fibrils‐induced damage in nasal epithelial, microglial and dopaminergic neuronal cell lines

Brain Pathology, EarlyView.
Omics‐driven drug repositioning reveals pyroxamide as a neuroprotective HDAC1 inhibitor in Parkinson's disease models. Abstract Parkinson's disease (PD) is the second most common neurodegenerative disorder mainly characterized by the degeneration of dopaminergic neurons originating in the substantia nigra (SN) pars compacta and projecting to other ...

Neuropathology of a patient with Parkinson's disease and biallelic expansion in RFC1

Brain Pathology, EarlyView.
This is the first report of neuropathology in biallelic RFC1 expansion‐associated Parkinson’s disease (PD). It shows a synucleinopathy of intraneuronal Lewy bodies consistent with the clinical PD diagnosis while neuropathological CANVAS (Cerebellar Ataxia with Neuropathy and bilateral Vestibular Areflexia) features were absent.
