This study demonstrates that Klk6 signals through PAR1 to regulate oligodendrocyte process stability and extension, myelin gene expression and cell survival in the presence of oligotoxic agents. Eleva...
KEY FINDING: Klk6 mediates loss of oligodendrocyte processes and impedes morphological differentiation of oligodendrocyte progenitor cells (OPCs) in a PAR1-dependent fashion.
PLoS ONE, 2012 • November 20, 2012
This study combined computational and biochemical methods to identify small molecule inhibitors of PTPs. The in silico docking showed that the identified compounds are molecularly accommodated by the ...
KEY FINDING: Several compounds were identified that inhibit PTPs activity in vitro with micromolar potency.
Frontiers in Neuroscience, 2014 • December 16, 2014
The review challenges long-held misconceptions regarding the history and functionality of the blood-brain barrier (BBB), particularly in developing organisms. It highlights misinterpretations of early...
KEY FINDING: Ehrlich did not believe cerebral blood vessels had different permeability than other organs.
Scientific Reports, 2015 • January 19, 2015
This study established a high-throughput platform to investigate astrocyte-substrate interactions, revealing that astrocytes align along microgrooves with elongated and deformed nuclei. The research i...
KEY FINDING: Astrocytes on micropatterned surfaces exhibit changes in cell and nuclear elongation and alignment compared to flat surfaces.
Int. J. Mol. Sci., 2012 • October 10, 2012
Successful nerve regeneration after nerve trauma is not only important for the restoration of motor and sensory functions, but also to reduce the potential for abnormal sensory impulse generation that...
KEY FINDING: Transplanted OECs integrate into peripheral nerve transected by crush injury, form peripheral-like myelin on regenerated peripheral nerve fibers and that the OECs are able to signal the regenerated axons to reconstruct nodes of Ranvier (Figure 1A,B) with proper sodium channel (Nav1.6) organization
Int. J. Mol. Sci., 2012 • October 19, 2012
This study examined changes in GDNF protein and mRNA expression levels in the spinal cord after hemi-transection in rats. The key finding was that GDNF protein accumulated in the rostral part of the i...
KEY FINDING: GDNF protein levels increase rapidly in the rostral part of the spinal cord after hemi-transection.
Journal of Biological Chemistry, 2013 • January 18, 2013
This study demonstrates that JNK1 is a key component in Netrin signaling, which is crucial for axon guidance during nervous system development. The researchers found that Netrin-1 activates JNK1 in ne...
KEY FINDING: Netrin-1 increases JNK1 activity, but not JNK2 or JNK3, in the presence of DCC or DSCAM, and expression of both further enhances Netrin-1-induced JNK1 activity in vitro.
The Journal of Neuroscience, 2012 • December 12, 2012
This study demonstrates that miR-21 expression increases in astrocytes following spinal cord injury (SCI) and plays a crucial role in regulating astrocytic hypertrophy and glial scar formation. Overex...
KEY FINDING: miR-21 expression increases in astrocytes adjacent to the lesion site following spinal cord injury (SCI).
BMC Biology, 2012 • December 17, 2012
This study demonstrates that axolotls can regenerate their lenses during a specific developmental window, challenging previous assumptions. The axolotl's lens regeneration process differs from both fr...
KEY FINDING: Axolotls can regenerate lenses from the iris within a specific time window after hatching, starting at stage 44 and lasting for about two weeks.
The Journal of Neuroscience, 2013 • January 2, 2013
This study identifies TRPC1 subunit-containing channels as mechanosensitive (MS) channels on spinal neuron growth cones. Increasing or decreasing MS channel activity alters axon outgrowth by influenci...
KEY FINDING: TRPC1 subunits assemble mechanosensitive channels on Xenopus neuronal growth cones, regulating axon outgrowth on rigid substrates.
