SUSTAINED EXOCYTOSIS AFTER ACTION POTENTIAL-LIKE STIMULATION AT LOW FREQUENCIES IN MOUSE CHROMAFFIN CELLS DEPENDS ON A DYNAMIN-DEPENDENT FAST ENDOCYTOTIC PROCESS

Frontiers in Cellular Neuroscience, 2016
Under basal conditions the action potential firing rate of adrenal chromaffin cells is lower than 0.5 Hz. The maintenance of the secretory response at such frequencies requires a continuous replenishment of releasable vesicles.

Dynamin Subunit Interactions Revealed [PDF]

Developmental Cell, 2010
Dynamin family members are large GTPases that assemble into multimeric spirals. These spirals promote membrane fission or fusion, or they inhibit processes such as viral replication. Two new studies by Chappie et al. and Gao et al. in a recent issue of Nature identify interactions between subunits of dynamin spirals, advancing mechanistic understanding

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

The role of scaffold reshaping and disassembly in dynamin driven membrane fission

eLife, 2018
The large GTPase dynamin catalyzes membrane fission in eukaryotic cells, but despite three decades of experimental work, competing and partially conflicting models persist regarding some of its most basic actions.

Tetraspanin‐ESCRT sorting drives miR‐29b packaging into extracellular vesicles to reverse fibrosis in intrauterine adhesions

BMEMat, EarlyView.
MiR‐29b is enriched in extracellular vesicles (EVs) via a tetraspanin transporter‐dependent endocytosis and sorting complex required for the endosomal transport (ESCRT)‐dependent pathway. These EVs target the 3′ untranslated region (3′UTR) of TGFB2, thereby inhibiting the TGF‐β/Smad3 signaling pathway and repairing endometrial damage in intrauterine ...

The BAR Domain Superfamily Proteins from Subcellular Structures to Human Diseases

Membranes, 2012
Eukaryotic cells have complicated membrane systems. The outermost plasma membrane contains various substructures, such as invaginations and protrusions, which are involved in endocytosis and cell migration.

α-Synuclein Dimers Impair Vesicle Fission during Clathrin-Mediated Synaptic Vesicle Recycling

Frontiers in Cellular Neuroscience, 2017
α-Synuclein is a presynaptic protein that regulates synaptic vesicle (SV) trafficking. In Parkinson’s disease (PD) and several other neurodegenerative disorders, aberrant oligomerization and aggregation of α-synuclein lead to synaptic dysfunction and ...

Microbial metabolite indole‐3‐propionic acid preserves astrocytic mitochondrial mitofusin 2 to limit neuroinflammation after traumatic brain injury

Interdisciplinary Medicine, EarlyView.
Following traumatic brain injury, indole‐3‐propionic acid (IPA) directly targets the aryl hydrocarbon receptor on astrocytes in the peri‐lesional cortex; this suppresses interferon regulatory factor 1‐driven transcription of the E3 ubiquitin ligase RFFL (ring finger and FYVE‐like domain containing E3 ubiquitin protein ligase).

Reversing brain aging: Targeting energy metabolism in endogenous neural stem cells

Interdisciplinary Medicine, EarlyView.
Mechanism of endogenous neural stem cells (eNSCs) energy metabolism disorder leading to brain aging and targeted eNSCs intervention strategies (By biorender). The disorder of energy metabolism of eNSCs can lead to their resting and aging, and eventually lead to brain aging.

Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.
