Soluble Aβ1–42 increases the heterogeneity in synaptic vesicle pool size among synapses by suppressing intersynaptic vesicle sharing

Molecular Brain, 2018
Growing evidence has indicated that prefibrillar form of soluble amyloid beta (sAβ1–42) is the major causative factor in the synaptic dysfunction associated with AD.

Synaptic Vesicles in the Fast Lane [PDF]

Science, 2004
It is well established that a subset of synaptic vesicles seem to be preferentially recycled after neurotransmitter release. It has been assumed that these vesicles must cluster at the active zones of the presynaptic nerve terminal membrane so that they can rapidly release their contents in response to electrical stimulation.

Smart Nanotechnologies for Multimodal Neuromodulation and Brain Interfacing

Advanced Science, EarlyView.
Recent advances in smart nanotechnologies are expanding the toolbox for brain interfacing, from wireless neuromodulation and high‐resolution sensing to targeted delivery within the central nervous system. By combining responsive nanomaterials with bioinspired design, these platforms enable multimodal interactions with neurons and glia, while also ...

Dissecting Synaptic Vesicle Endocytosis [PDF]

, 2012
Synaptic vesicle endocytosis is critical for ensuring rapid local recycling of synaptic vesicles to enable ongoing neuronal activity. We utilized the sensitivity and robustness of the pHluorin assay of synaptic vesicle recycling to probe the control of ...

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Spontaneous Vesicle Recycling in the Synaptic Bouton

Frontiers in Cellular Neuroscience, 2014
The trigger for synaptic vesicle exocytosis is Ca2+, which enters the synaptic bouton following action potential stimulation. However, spontaneous release of neurotransmitter also occurs in the absence of stimulation in virtually all synaptic boutons. It

Secretory vesicles are preferentially targeted to areas of low molecular SNARE density [PDF]

, 2012
Intercellular communication is commonly mediated by the regulated fusion, or exocytosis, of vesicles with the cell surface. SNARE (soluble N-ethymaleimide sensitive factor attachment protein receptor) proteins are the catalytic core of the secretory ...

Condition‐Associated Pattern Extraction and Recovery From Multi‐Condition Single‐Cell RNA‐seq Data With CAPER

Advanced Science, EarlyView.
Decoupling biological signals from unwanted variation in multi‑condition single‑cell RNA sequencing data remains challenging. CAPER disentangles condition‑associated biological effects from sample heterogeneity through matrix factorization, producing interpretable latent factors and a batch‑corrected expression matrix.

Sharing vesicles between central presynaptic terminals: implications for synaptic function

Frontiers in Synaptic Neuroscience, 2010
Presynaptic terminals in hippocampal neurons house functionally distinct vesicle pools, the size, structure and biochemical features of which are major determinants of presynaptic strength and performance.

Anisotropic Memristive Switching in NbOCl2 Enabled by Directional Oxygen Ion Migration

Advanced Science, EarlyView.
This study investigates strongly orientation‐dependent memristive switching in anisotropic NbOCl2, observed exclusively along the in‐plane c‐axis. The switching originates from direction‐selective oxygen‐ion migration and vacancy propagation that modulate the Pd/NbOCl2 Schottky barrier, enabling short‐term plasticity.
