Neuronal activity inhibits mitochondrial transport only in synaptically connected segments of the axon

Frontiers in Cellular Neuroscience
Due to their large scale and uniquely branched architecture, neurons critically rely on active transport of mitochondria in order to match energy production and calcium buffering to local demand.

Axonal Transport: A Constrained System [PDF]

Journal of Neurology and Neuromedicine, 2017
Long-distance intracellular axonal transport is predominantly microtubule-based, and its impairment is linked to neurodegeneration. Here we review recent theoretical and experimental evidence that suggest that near the axon boundaries (walls), the effective viscosity can become large enough to impede cargo transport in small (but not large) caliber ...

Hyperglycemia induces oxidative stress and impairs axonal transport rates in mice. [PDF]

PLoS ONE, 2010
While hyperglycemia-induced oxidative stress damages peripheral neurons, technical limitations have, in part, prevented in vivo studies to determine the effect of hyperglycemia on the neurons in the central nervous system (CNS).

Profiling Axonal mRNA Transport [PDF]

, 2011
The importance of mRNA localization and localized protein synthesis to spatially modulate protein levels in distinct subcellular domains has increasingly been recognized in recent years. Axonal and dendritic processes of neurons represent separate functional domains of the cell that have shown the capacity to autonomously respond to extracellular ...

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

Advanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Biomimetic Vascular Scaffold with Seamless Electrospun Aligned Nanofiber Conduit and 3D‐Printed Coil Reinforcement

Advanced Healthcare Materials, EarlyView.
We introduce a new fabrication method that overcomes the current limitation of tubular gap electrospinning. We successfully fabricated a seamless hollow tube with fibers aligned along the longitudinal axis in diameters as small as 300 µm, and then reinforced it using 4‐axis 3D printing.

Live Imaging of Axonal Transport in the Motor Neurons of Drosophila Larvae

Bio-Protocol, 2017
Axonal transport, which is composed of microtubules, motor proteins and a variety of types of cargo, is a prominent feature of neurons. Monitoring these molecular dynamics is important to understand the biological processes of neurons as well as ...

Engineering Nanoplatforms for Alzheimer's Disease Detection via Biomolecular Corona Proteomic and Lipidomic Profiling

Advanced Healthcare Materials, EarlyView.
Engineered nanoparticles capture disease‐specific biomolecular coronas that uncover hidden molecular features of Alzheimer's disease. Combined proteomic and lipidomic analyses reveal a characteristic shift in ribosomal machinery and energy metabolism, generating a multiomic fingerprint that supports accurate disease detection and opens new ...
