Behavioral defects associated with amygdala and cortical dysfunction in mice with seeded α-synuclein inclusions

Neurobiology of Disease, 2020
Parkinson's disease (PD) is defined by motor symptoms such as tremor at rest, bradykinesia, postural instability, and stiffness. In addition to the classical motor defects that define PD, up to 80% of patients experience cognitive changes and psychiatric

AMPK-autophagy-mediated inhibition of microRNA-30a-5p alleviates morphine tolerance via SOCS3-dependent neuroinflammation suppression

Journal of Neuroinflammation, 2022
Background The development of morphine tolerance is a clinical challenge for managing severe pain. Studies have shown that neuroinflammation is a critical aspect for the development of analgesic tolerance.

A manifesto for Alzheimer’s disease drug discovery in the era of disease-modifying therapies

Molecular Neurodegeneration
After decades of disappointment, three disease-modifying therapies for Alzheimer’s disease (AD) have been approved since 2021. Burgeoning clinical data on these amyloid β-protein (Aβ) targeting drugs validate the amyloid cascade hypothesis as a molecular

Conditional deletion of ROCK2 induces anxiety-like behaviors and alters dendritic spine density and morphology on CA1 pyramidal neurons

Molecular Brain, 2021
Rho-associated kinase isoform 2 (ROCK2) is an attractive drug target for several neurologic disorders. A critical barrier to ROCK2-based research and therapeutics is the lack of a mouse model that enables investigation of ROCK2 with spatial and temporal ...

C9orf72 repeat expansions cause neurodegeneration in Drosophila through arginine-rich proteins

, 2014
An expanded GGGGCC repeat in C9orf72 is the most common genetic cause of frontotemporal dementia and amyotrophic lateral sclerosis. A fundamental question is whether toxicity is driven by the repeat RNA itself and/or by dipeptide repeat proteins ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Autophagy and Neurodegeneration [PDF]

Autophagy, 2006
The proteasome and lysosome are sophisticated apparatuses capable of shredding unnecessary proteins in eukaryotic cells. The proteasome and its partner ubiquitin (which functions as a destination signal for proteolysis) play crucial roles in selective breakdown of not only short-lived regulatory proteins but also abnormal proteins that need to be ...

Stress granules formation in HEI-OC1 auditory cells and in H4 human neuroglioma cells secondary to cisplatin exposure

Cell Stress
Stress granules (SGs) are highly dynamic micromolecular membraneless condensates that generate in cells subjected to stress. Formed from pools of untranslating messenger ribonucleoproteins (RNP), SGs dynamics constitute vital processes essential for cell

Pathological α-synuclein recruits LRRK2 expressing pro-inflammatory monocytes to the brain

Molecular Neurodegeneration, 2022
Background Leucine rich repeat kinase 2 (LRRK2) and SNCA are genetically linked to late-onset Parkinson’s disease (PD). Aggregated α-synuclein pathologically defines PD.

Microglia in neurodegeneration

Nature Neuroscience, 2018
The neuroimmune system is involved in development, normal functioning, aging, and injury of the central nervous system. Microglia, first described a century ago, are the main neuroimmune cells and have three essential functions: a sentinel function involved in constant sensing of changes in their environment, a housekeeping function that promotes ...
