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.

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

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.

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 ...

Bioengineered microbiotic levodopa therapy improves cognition and reduces pathology in a rat model of Alzheimer's disease

British Journal of Pharmacology, EarlyView.
Background and Purpose Degeneration of the pontine noradrenergic and midbrain dopaminergic systems contributes to cognitive‐behavioural disturbances during the prodromal stages of Alzheimer's disease (AD). We developed a genetically engineered, programmable probiotic Escherichia coli Nissle 1917 strain (EcNrhaL‐DOPA) capable of producing L‐3,4 ...

Identification of Copy Number Variants as a Suspected Cause of Cerebral Small Vessel Disease

Clinical Genetics, EarlyView.
Whole‐exome sequencing of 111 patients with suspected familial cerebral small vessel disease (CSVD) identified novel copy number variants in four patients across NOTCH3, LMNB1, and COL4A2, using bioinformatic and molecular techniques. These validated CNVs suggest structural variation is an underrecognized potential causal contributor to monogenic CSVD ...

Shared dysregulation of complement and phosphorylation pathways in the cerebrospinal fluid of encephalitis, Aicardi–Goutières syndrome, and autism

Developmental Medicine &Child Neurology, EarlyView.
Abstract Aim To identify shared and disorder‐specific molecular alterations across encephalitis, Aicardi–Goutières syndrome (AGS), and autism spectrum disorder (ASD) using cerebrospinal fluid (CSF) proteomics. Method In this cross‐sectional case–control study, mass‐spectrometry‐based proteomics was performed on archived CSF samples collected between ...
