MIF versus SIF motoneurons, what are their respective contribution in the oculomotor medial rectus pool?
(Society for Neuroscience, 2021)
Multiply-innervated muscle fibers (MIFs) are peculiar to the extraocular muscles as they are non-twitch but produce a slow build up in tension on repetitive stimulation. The motoneurons innervating MIFs establish en grappe ...

A Single Intraventricular Injection of VEGF Leads to Long-Term Neurotrophic Effects in Axotomized Motoneurons
(Society for Neuroscience, 2020)
Vascular endothelial growth factor (VEGF) has been recently demonstrated to induce neuroprotective and synaptotrophic effects on lesioned neurons. Hitherto, the administration of VEGF in different animal models of lesion ...

VEGF and Neuronal Survival
(SAGE, 2022)
Vascular endothelial growth factor (VEGF) is well known for its angiogenic activity, but recent evidence has revealed a neuroprotective action of this factor on injured or diseased neurons. In the present review, we summarize ...

Role of Vascular Endothelial Growth Factor as a Critical Neurotrophic Factor for the Survival and Physiology of Motoneurons
(Wolters Kluwer Health, 2023)
Vascular endothelial growth factor (VEGF) was discovered by its angiogenic activity. However, during evolution, it appeared earlier as a neurotrophic factor required for the development of the nervous system in invertebrates ...

Preservation of KCC2 expression in axotomized abducens motoneurons and its enhancement by VEGF
(Springer Nature, 2023)
The potassium chloride cotransporter 2 (KCC2) is the main Cl− extruder in neurons. Any alteration in KCC2 levels leads to changes in Cl− homeostasis and, consequently, in the polarity and amplitude of inhibitory synaptic ...

Relative contribution of lateral vestibular neuron and abducens internuclear neuron inputs to the discharge activity of medial rectus motoneurons
(Springer, 2023)
Medial rectus motoneurons mediate nasally directed horizontal eye movements. These motoneurons receive two major excitatory inputs, from the abducens internuclear neurons (ABD Ints) and neurons of the lateral vestibular ...

Eye Movements But Not Vision Drive the Development of Palisade Endings
(Association for Research in Vision and Ophthalmology, 2022)
PURPOSE. To test whether visual experience and/or eye movements drive the postnatal development of palisade endings in extraocular muscles. METHODS. In three newborn cats, the right eye was covered until 30 days from ...

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 ...

Palisade endings have an exocytotic machinery but lack acetylcholine receptors and distinct acetylcholinesterase activity
(ARVO, 2020)
Purpose: The purpose of this work was to test whether palisade endings express structural and molecular features of exocytotic machinery, and are associated with acetylcholine receptors, and enzymes for neurotransmitter ...
