Dual encoding of muscle tension and eye position by abducens motoneurons
(Society for Neuroscience, 2011)
Extraocular muscle tension associated with spontaneous eye movements has a pulse-slide-step profile similar to that of motoneuron firing rate. Existing models only relate motoneuron firing to eye position, velocity and ...

VEGF is an essential retrograde trophic factor for motoneurons
(National Academy of Sciences, 2022)
VEGF was initially discovered due to its angiogenic activity and therefore named "vascular endothelial growth factor."However, its more recently discovered neurotrophic activity may be evolutionarily more ancient. Our ...

Proprioceptors in extraocular muscles
(Wiley-Blackwell, 2023)
New Findings: What is the topic of this review? This review aims to evaluate the literature on proprioceptors and particular nerve specializations (palisade endings) in mammalian extraocular muscles (EOMs) and to reconsider ...

Complementary Actions of BDNF and Neurotrophin-3 on the Firing Patterns and Synaptic Composition of Motoneurons
(Society for Neuroscience, 2009)
Neurotrophins, as target-derived factors, are essential for neuronal survival during development, but during adulthood, their scope of actions widens to become also mediators of synaptic and morphological plasticity. Target ...

Extraocular Motor System Exhibits a Higher Expression of Neurotrophins When Compared with Other Brainstem Motor Systems
(Frontiers Media, 2017)
Extraocular motoneurons resist degeneration in diseases such as amyotrophic lateral sclerosis. The main objective of the present work was to characterize the presence of neurotrophins in extraocular motoneurons and muscles ...

Synaptic loss and firing alterations in Axotomized Motoneurons are restored by vascular endothelial growth factor (VEGF) and VEGF-B
(Elsevier, 2018)
Vascular endothelial growth factor (VEGF), also known as VEGF-A, was discovered due to its vasculogenic and angiogenic activity, but a neuroprotective role for VEGF was later proven for lesions and disorders. In different ...

Neuroprotective Effect of Vascular Endothelial Growth Factor on Motoneurons of the Oculomotor System
(MDPI, 2021-01)
Vascular endothelial growth factor (VEGF) was initially characterized as a potent angiogenic factor based on its activity on the vascular system. However, it is now well established that VEGF also plays a crucial role as ...

Implanted neural progenitor cells regulate glial reaction to brain injury and establish gap junctions with host glial cells
(Wiley-Blackwell, 2014)
Transplantation of neural stem/progenitor cells (NPCs) in the lesioned brain is able to restore morphological and physiological alterations induced by different injuries. The local microenvironment created at the site of ...

Purinergic Receptor Blockade with Suramin Increases Survival of Postnatal Neural Progenitor Cells In Vitro
(MDPI, 2021)
Neural progenitor cells (NPCs) are self-renewing and multipotent cells that persist in the postnatal and adult brain in the subventricular zone and the hippocampus. NPCs can be expanded in vitro to be used in cell therapy. ...
