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 ...

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 ...

Short-term plasticity after partial deafferentation in the oculomotor system
(Springer Nature, 2019)
Medial rectus motoneurons are innervated by two main pontine inputs. The specific function of each of these two inputs remains to be fully understood. Indeed, selective partial deafferentation of medial rectus motoneurons, ...

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 ...

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 ...

Extraocular motoneurons of the adult rat show higher levels of vascular endothelial growth factor and its receptor Flk-1 than other cranial motoneurons
(Public Library of Science, 2017)
Recent studies show a relationship between the deficit of vascular endothelial growth factor (VEGF) and motoneuronal degeneration, such as that occurring in amyotrophic lateral sclerosis (ALS). VEGF delivery protects ...
Artículo
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 ...

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 ...

Functional diversity of motoneurons in the oculomotor system
(National Academy of Sciences, 2019-02-26)
Extraocular muscles contain two types of muscle fibers according to their innervation pattern: singly innervated muscle fibers (SIFs), similar to most skeletal muscle fibers, and multiply innervated muscle fibers (MIFs). ...

BDNF Influence on Adult Terminal Axon Sprouting after Partial Deafferentation
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
BDNF is a neurotrophin family member implicated in many different neuronal functions, from neuronal survival during development to synaptic plasticity associated with processes of learning and memory. Its presence in the ...
