PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

α‐Synuclein aggregation landscape from phase separation to neurotoxic intermediates

open access: yesFEBS Letters, EarlyView.
Alpha‐synuclein aggregation in Parkinson's disease involves a complex landscape of transient intermediates, including oligomers, fibrils and liquid–liquid phase separation (LLPS). A view is emerging in which LLPS maturation into solid‐like condensates may contribute to the formation of neurotoxic species.

Specific biomarkers for C9orf72 FTD/ALS could expedite the journey towards effective therapies

open access: yesEMBO Molecular Medicine, 2017
A hexanucleotide repeat expansion in the C9orf72 gene is a common genetic cause of ALS and FTD. The repeats are translated into five different dipeptide repeat proteins (DPRs).

Prominent amyloid plaque pathology and cerebral amyloid angiopathy in APP V717I (London) carrier – phenotypic variability in autosomal dominant Alzheimer’s disease

open access: yesActa Neuropathologica Communications, 2020
The discovery of mutations associated with familial forms of Alzheimer’s disease (AD), has brought imperative insights into basic mechanisms of disease pathogenesis and progression and has allowed researchers to create animal models that assist in the ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Iron deficiency in parkinsonism : region-specific iron dysregulation in Parkinson's disease and multiple system atrophy [PDF]

open access: yes
Alpha synuclein pathology is widespread and found in diverse cell types in multiple system atrophy (MSA) as compared to Parkinson's disease (PD). The reason for this differential distribution is unknown.

Expert consensus on diagnostic management specification and biomarker disclosure for subjective cognitive decline

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery
The concept of subjective cognitive decline (SCD) is currently receiving much attention, as SCD has a high risk of transitioning to mild cognitive impairment (MCI) and dementia.

Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

open access: yeseLife, 2019
Calcium is a critical second messenger in neurons that contributes to learning and memory, but how the coordination of action potentials of neuronal ensembles with the hippocampal local field potential (LFP) is reflected in dynamic calcium activity ...

Impaired phonemic discrimination in logopenic variant primary progressive aphasia

open access: yesAnnals of Clinical and Translational Neurology, 2020
Logopenic variant primary progressive aphasia (lvPPA) is the least well defined of the major primary progressive aphasia (PPA) syndromes. We assessed phoneme discrimination in patients with PPA (semantic, nonfluent/agrammatic, and logopenic variants) and
