A 3D Biofabricated Disease Model Mimicking the Brain Extracellular Matrix Suitable to Characterize Intrinsic Neuronal Network Alterations in the Presence of a Breast Tumor Disseminated to the Brain

open access: yesAdvanced Functional Materials, EarlyView.
A 3D disease model is developed using customized hyaluronic‐acid‐based hydrogels supplemented with extracellular matrix (ECM) proteins resembling brain ECM properties. Neurons, astrocytes, and tumor cells are used to mimic the native brain surrounding.

Mechanisms of Axon Elongation Following CNS Injury: What Is Happening at the Axon Tip?

open access: yesFrontiers in Cellular Neuroscience, 2020
After an injury to the central nervous system (CNS), functional recovery is limited by the inability of severed axons to regenerate and form functional connections with appropriate target neurons beyond the injury.

Role of GPR55 during Axon Growth and Target Innervation

open access: yeseNeuro, 2015
Guidance molecules regulate the navigation of retinal ganglion cell (RGC) projections toward targets in the visual thalamus. In this study, we demonstrate that the G-protein-coupled receptor 55 (GPR55) is expressed in the retina during development, and ...

Intra-Axonal Translation of RhoA Promotes Axon Growth Inhibition by CSPG [PDF]

open access: yesThe Journal of Neuroscience, 2012
Chondroitin sulfate proteoglycans (CSPGs) are a major component of the glial scar that contributes to the limited regeneration of the CNS after axonal injury. However, the intracellular mechanisms that mediate the effects of CSPGs are not fully understood.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Retrograde Ret signaling controls sensory pioneer axon outgrowth

open access: yeseLife, 2019
The trafficking mechanisms and transcriptional targets downstream of long-range neurotrophic factor ligand/receptor signaling that promote axon growth are incompletely understood. Zebrafish carrying a null mutation in a neurotrophic factor receptor, Ret,

Rac1 plays an essential role in axon growth and guidance and in neuronal survival in the central and peripheral nervous systems

open access: yesNeural Development, 2015
BackgroundRac1 is a critical regulator of cytoskeletal dynamics in multiple cell types. In the nervous system, it has been implicated in the control of cell proliferation, neuronal migration, and axon development.ResultsTo systematically investigate the ...

Region‐to‐Region Unidirectional Connection In Vitro Brain Model for Studying Directional Propagation of Neuropathologies

open access: yesAdvanced Functional Materials, EarlyView.
A unidirectional cerebral organoid–organoid neural circuit is established using a microfluidic platform, enabling controlled directional propagation of electrical signals, neuroinflammatory cues, and neurodegenerative disease–related proteins between spatially separated organoids.

A neural network growing algorithm based on Brownian movement and gravity constraint

open access: yesAdvances in Mechanical Engineering, 2018
A growing algorithm of neural network based on axon growth is developed in this article. At the beginning, the Newtonian gravitation and the Brownian motion are employed to establish an axon growth model, and the constraint function of the neural axon ...

Gene Manipulation Strategies to Identify Molecular Regulators of Axon Regeneration in the Central Nervous System

open access: yesFrontiers in Cellular Neuroscience, 2017
Limited axon regeneration in the injured adult mammalian central nervous system (CNS) usually results in irreversible functional deficits. Both the presence of extrinsic inhibitory molecules at the injury site and the intrinsically low capacity of adult ...
