Ontogeny of synaptophysin and synaptoporin in the central nervous system [PDF]

, 1993
The expression of the synaptic vesicle antigens synaptophysin (SY) and synaptoporin (SO) was studied in the rat striatum, which contains a nearly homogeneous population of GABAergic neurons. In situ hybridization revealed high levels of SY transcripts in

Unraveling 4‐Phenylbutyrate's Therapeutic Role in SLC6A1 Disorders: Pharmacochaperoning Over HDAC Inhibition

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Variants in SLC6A1, encoding the GABA transporter 1 (GAT‐1), cause epilepsy, autism spectrum disorder, and developmental delay via loss of GABA uptake, impaired trafficking, and ER retention. We previously found that 4‐Phenylbutyrate (PBA), an FDA‐approved drug, restores GABA uptake and reduces seizures in SLC6A1‐related disorders ...

Diabetes‐Associated Cognitive Impairment: Pathophysiology and Emerging Therapies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diabetes‐associated cognitive impairment (DACI) is a common yet underrecognized condition, manifesting along a spectrum from mild cognitive impairment to dementia. DACI encompasses patients who develop vascular dementia (VaD) or Alzheimer's disease (AD) with diabetes as a risk factor; however, in certain patients, particularly those lacking ...

Botulinum neurotoxin Light Chain/A1 uses fast synaptic vesicle cycling to cleave plasma membrane bound SNAP-25

Communications Biology
Botulinum neurotoxins (BoNT) are the most potent protein toxins for humans, yet how BoNT-Light Chain/A1 (LC/A1) journeys to cleave intracellular SNAP-25 is understudied.

Levetiracetam Mechanisms of Action: From Molecules to Systems

Pharmaceuticals, 2022
Epilepsy is a chronic disease that affects millions of people worldwide. Antiepileptic drugs (AEDs) are used to control seizures. Even though parts of their mechanisms of action are known, there are still components that need to be studied.

Casein kinase 2 controls synapse organization and stability [PDF]

, 2013
Synapse remodeling is a local and dynamic process, requiring constant modifications of the neuronal network. Post-translational modifications, such as reversible phosphorylation by kinases and phosphatases, play a crucial role in synapse development and ...

GDNF‐Enriched Small Extracellular Vesicle‐Loaded ROS‐Scavenging Hydrogel Promotes Neural Regeneration After Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
A glial cell line‐derived neurotrophic factor (GDNF)‐enriched small extracellular vesicle‐loaded reactive oxygen species (ROS)‐scavenging hydrogel integrates sustained neurotrophic delivery with local modulation of oxidative and inflammatory stress after spinal cord injury. The composite hydrogel improves local vesicle retention, protects neural tissue,

AKAP1 Protects Retinal Ganglion Cells and Preserves Vision by Improving Mitochondrial and Synaptic Health in Glaucomatous Neurodegeneration. [PDF]

Adv Sci (Weinh)
Intravitreal AAV2‐mediated AKAP1 restoration enhances mitochondrial fusion and biogenesis, improves bioenergetic capacity, and preserves mitochondrial integrity in glaucomatous RGCs. AKAP1 stabilizes presynaptic structure, maintaining synaptic protein expression, and limiting complement‐associated neuroinflammation.

Anti‐Inflammatory and Neuroactive Effects of Polymer‐Coated Iron Oxide Nanoparticles Functionalized With Interleukin 4 for Spinal Cord Injury

Advanced Healthcare Materials, EarlyView.
Polymer‐coated IONPs functionalized with IL‐4 display respective neuroactive and anti‐inflammatory actions on neural progenitor cells and macrophages/microglia in vitro. When examined chronically in a rat experimental model of spinal cord injury, rGO scaffolds carrying these nanosystems adequately integrate into the lesion, significantly reduce ...

Assessment of changes in synaptic density in the zQ175DN mouse model of Huntington’s disease: a [18F]SynVesT-1 study

NeuroImage: Clinical
Huntington’s disease (HD) is a neurodegenerative disorder characterized by involuntary movements, cognitive decline and psychiatric problems. HD has been associated with synaptic dysfunction and loss of the synaptic vesicle protein 2A (SV2A).
