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 ...

Differential regulation of the expression of neurotrophin receptors in rat extraocular motoneurons after lesion
(Wiley, 2011)
Neurotrophins acting through high-affinity tyrosine kinase receptors (trkA, trkB, and trkC) play a crucial role in regulating survival and maintenance of specific neuronal functions after injury. Adult motoneurons supplying ...

Regulation of Gephyrin Cluster Size and Inhibitory Synaptic Currents on Renshaw Cells by Motor Axon Excitatory Inputs
(Society for Neuroscience, 2005)
Renshaw cells receive a high density of inhibitory synapses characterized by large postsynaptic gephyrin clusters and mixed glycinergic/ GABAergic inhibitory currents with large peak amplitudes and long decays. These ...

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 ...

Interactions between neural progenitor cells and microglia in the subventricular zone: physiological implications in the neurogenic niche and after implantation in the injured brain
(Frontiers Media, 2018)
The adult subventricular zone (SVZ) of the mammalian brain contains neural progenitor cells (NPCs) that continuously produce neuroblasts throughout life. These neuroblasts migrate towards the olfactory bulb where they ...

Palisade Endings Are a Constant Feature in the Extraocular Muscles of Frontal-Eyed, But Not Lateral-Eyed, Animals
(Association for Research in Vision and Ophthalmology, 2016)
Purpose To test whether palisade endings are a general feature of mammalian extraocular muscles (EOMs). Methods Thirteen species, some frontal-eyed (human, monkey, cat, and ferret), and others lateral-eyed (pig, ...

Axons Giving Rise to the Palisade Endings of Feline Extraocular Muscles Display Motor Features
(Society for Neuroscience, 2013)
Palisade endings are nerve specializations found in the extraocular muscles (EOMs) of mammals, including primates. They have long been postulated to be proprioceptors. It was recently demonstrated that palisade endings are ...
