Acute Complexin Knockout Abates Spontaneous and Evoked Transmitter Release

Cell Reports, 2019
Summary: SNARE-mediated synaptic vesicle (SV) fusion is controlled by multiple regulatory proteins that determine neurotransmitter release efficiency.

Nanoscale Mapping of the Subcellular Glycosylation Landscape

Advanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Vitamin D Regulates Olfactory Function via Dual Transcriptional and mTOR‐Dependent Translational Control of Synaptic Proteins

Advanced Science, EarlyView.
Vitamin D (VitD) modulates olfactory function by remodeling dendrodendritic synapses in tufted cells through vitamin D receptor‐dependent transcriptional and translational mechanisms. VitD regulates synaptic protein translation partially via mTOR signaling.

ADAR-mediated RNA editing suppresses sleep by acting as a brake on glutamatergic synaptic plasticity. [PDF]

, 2016
It has been postulated that synaptic potentiation during waking is offset by a homoeostatic reduction in net synaptic strength during sleep. However, molecular mechanisms to support such a process are lacking. Here we demonstrate that deficiencies in the

Reduced synaptic vesicle protein degradation at lysosomes curbs TBC1D24/sky-induced neurodegeneration

Journal of Cell Biology, 2014
Efficient lysosome-mediated turnover of synaptic vesicle-associated proteins is necessary for synaptic transmission and protection from neurodegeneration in Drosophila.

Scattering synaptic vesicles [PDF]

The Journal of Cell Biology, 2006
![][1] The BDNF-induced increase (left) in synapses (red) on a neuron (green) is lost if β-catenin and cadherin are locked together (right). Synaptic vesicles get dispersed to new sites, according to Bamji et al.

Stochastic Nanoscale Biophysical Cues as a Basis for the Induction of Glioblastoma‐Like Transcriptional Programs in Astrocytes

Advanced Science, EarlyView.
Stochastic nanoscale physical cues induce glioblastoma (GBM)‐associated transcriptional traits in naïve astrocytes leading to spontaneous formation of spheroids. Cells within spheroids express activated‐MMP2 and a differential gene expression pattern involving P53 and NOTCH3, providing evidence for a role for changes in brain topography, as observed in

Otoferlin acts as a Ca2+ sensor for vesicle fusion and vesicle pool replenishment at auditory hair cell ribbon synapses

eLife, 2017
Hearing relies on rapid, temporally precise, and sustained neurotransmitter release at the ribbon synapses of sensory cells, the inner hair cells (IHCs).

Acute increase of α-synuclein inhibits synaptic vesicle recycling evoked during intense stimulation

Molecular Biology of the Cell, 2014
This is the first study to show the direct effects of α-synuclein on synaptic vesicle trafficking and to elucidate the underlying structural mechanisms. Acutely increasing α-synuclein severely inhibits synaptic vesicle recycling from the plasma membrane.
