Myelination: all about Rac n roll. [PDF]

, 2007
During the development of the peripheral nervous system, Schwann cells select individual axons from a nerve bundle and establish a one-to-one relationship through a process termed radial sorting. Recent findings identify the Rho family GTPase Rac1 as the

Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

Advanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

Induced Stem Cells as a Novel Multiple Sclerosis Therapy. [PDF]

, 2016
Stem cell replacement is providing hope for many degenerative diseases that lack effective therapeutic methods including multiple sclerosis (MS), an inflammatory demyelinating disease of the central nervous system. Transplantation of neural stem cells or

Neurotrophin‐3 targets the translational initiation machinery in oligodendrocytes [PDF]

Glia, 2009
AbstractNeurotrophin‐3 (NT‐3) regulates oligodendrocyte (OLG) differentiation by mechanisms that remain poorly understood. Exposure of OLGs to NT‐3 induces a significant increase in the levels of myelin basic protein (MBP). However, we found that this stimulation occurs in the absence of measurable effects on MBP gene promoter activation or mRNA ...

Advanced Biomaterial Delivery of Hypoxia‐Conditioned Extracellular Vesicles (EVs) as a Therapeutic Platform for Traumatic Brain Injury

Advanced Science, EarlyView.
This research introduces a novel approach to enhance neuroregeneration following Traumatic Brain Injury (TBI). Extracellular Vesicles (EVs) are isolated from human neural progenitor cells under hypoxic conditions, leading to enhanced expression of neurogenic and angiogenic factors.

Neurotrophin gene therapy for sustained neural preservation after deafness.

PLoS ONE, 2012
The cochlear implant provides auditory cues to profoundly deaf patients by electrically stimulating the residual spiral ganglion neurons. These neurons, however, undergo progressive degeneration after hearing loss, marked initially by peripheral fibre ...

One‐Step Drug Screening System Utilizing Electrophysiological Activity in Multiple Brain Organoids

Advanced Science, EarlyView.
This study presents a one‐step system that delivers different drug doses to brain organoids and monitors their neural activity using integrated 3D microelectrodes. By combining dose‐specific microfluidic delivery with high‐resolution electrophysiological recording, the platform enables simultaneous, real‐time screening of neural responses across ...

Remodeling of lumbar motor circuitry remote to a thoracic spinal cord injury promotes locomotor recovery

eLife, 2018
Retrogradely-transported neurotrophin signaling plays an important role in regulating neural circuit specificity. Here we investigated whether targeted delivery of neurotrophin-3 (NT-3) to lumbar motoneurons (MNs) caudal to a thoracic (T10) contusive ...

CGRP‐Loaded ROS‐Responsive Hydrogel Restores Neuro‐Angiogenic Signaling to Promote Bone Regeneration in Diabetes‐Associated Periodontitis

Advanced Science, EarlyView.
This study shows that diabetes damages sensory nerve fibers, especially CGRP‐positive ones, in the periodontium and disrupts autophagy in trigeminal ganglion neurons, affecting bone homeostasis by inhibiting type H vessel formation. To address this, CGRP@PVA/tsPBA hydrogels are developed to release CGRP in response to ROS, which binds to endothelial ...

Comparative study of gp130 cytokine effects on corticotroph AtT-20 cells - Redundancy or specificity of neuroimmunoendocrine modulators? [PDF]

, 2004
Objective: This comparative in vitro study examined the effects of all known gp130 cytokines on murine corticotroph AtT-20 cell function. Methods: Cytokines were tested at equimolar concentrations from 0.078 to 10 nM.
