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

open access: yesAdvanced Science, EarlyView.
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.

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

open access: yesFrontiers 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.

Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

open access: yesAdvanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...

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

open access: yeseLife, 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.

DUSP26 Regulated by YY1 Lactylation Couples Osteogenesis and Angiogenesis by Dephosphorylating PMPCB at Y141 and Activating Mitophagy in BMSCs

open access: yesAdvanced Science, EarlyView.
p300‐associated YY1 lactylation promotes DUSP26 expression in BMSCs. By regulating PMPCB phosphorylation and PINK1 processing, DUSP26 supports mitophagy, osteogenic differentiation, and pro‐angiogenic factor secretion. BMSC‐derived exosomes carrying a RUNX2 promoter‐driven DUSP26 plasmid favor osteogenic‐lineage transgene expression, partially ...

The BAR Domain Superfamily Proteins from Subcellular Structures to Human Diseases

open access: yesMembranes, 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.

Patient‐Derived Fibroblasts as a Clinically Relevant Model of Kearns–Sayre Syndrome

open access: yesAnnals of Neurology, EarlyView.
Objective Kearns–Sayre syndrome (KSS) is characterized by single large‐scale mitochondrial DNA deletions and by severe early‐onset clinical manifestations with neurological involvement. Reliable disease models, as well as validated biomarkers or effective treatments, are lacking.

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

open access: yesFrontiers 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 ...

Endogenous Trigeminal Neurons Induce Schwann Differentiation of Donor Stem Cells in Dental Pulp Regeneration via Reciprocal Extracellular Vesicles Interplay

open access: yesExploration, EarlyView.
Our study demonstrates that the host TG coordinates with heterologously implanted SHED to regenerate functional dental pulp through reciprocal EVs’ interplay. EVs derived from implanted stem cells migrate to the host TG to activate axonal regeneration.

Research Progress of Berberine in Kidney Disease: Targeting Mitochondria and Ferroptosis

open access: yesiNew Medicine, EarlyView.
This figure illustrates the model‐specific renoprotective mechanisms of berberine (BBR) across three major kidney diseases. From left to right, the diagram shows that BBR targets distinct core pathways depending on the pathological context: in diabetic nephropathy (DN), BBR activates AMPK to improve mitochondrial energy metabolism; in acute kidney ...
