Altered Intracellular Ca2+ Homeostasis in Nerve Terminals of Severe Spinal Muscular Atrophy Mice
(SOC NEUROSCIENCE, 2010)
Low levels of survival motor neuron (SMN) protein result in spinal muscular atrophy (SMA), a severe genetic disease characterized by motor impairment and premature lethality. Although SMN is a ubiquitous protein, motor ...

Morphological and functional remodelling of the neuromuscular junction by skeletal muscle PGC-1 alpha
(NATURE PUBLISHING GROUP, 2014-04-04)
The neuromuscular junction (NMJ) exhibits high morphological and functional plasticity. In the mature muscle, the relative levels of physical activity are the major determinants of NMJ function. Classically, motor ...

Active zones and the readily releasable pool of synaptic vesicles at the neuromuscular junction of the mouse
(SOC NEUROSCIENCE, 2011-02-09)
Synchronous neurotransmitter releaseis a highly regulated processthattakes place at specializations atthe presynapticmembrane called active zones (AZs). The relationships between AZs, quantal release, and vesicle replenishment ...

Multiple Functions of the Vesicular Proton Pump in Nerve Terminals
(Cell Press, 2010-12-22)
Synaptic vesicles are acidified by a proton pump (vATPase), which allows vesicular uptake of neurotransmitters. After vesicle exocytosis, continued operation of the vATPase would seem to serve no useful function. In this ...

Ciliary neurotrophic factor-induced sprouting preserves motor function in a mouse model of mild spinal muscular atrophy
(OXFORD UNIV PRESS, 2010)
Proximal spinal muscular atrophy (SMA) is caused by homozygous loss or mutation of the SMN1 gene on human chromosome 5. Depending on the levels of SMN protein produced from a second SMN gene (SMN2), different forms of ...

BDNF is a mediator of glycolytic fiber-type specification in mouse skeletal muscle
(NATL ACAD SCIENCES, 2019-07-18)
Brain-derived neurotrophic factor (BDNF) influences the differentiation, plasticity, and survival of central neurons and likewise, affects the development of the neuromuscular system. Besides its neuronal origin, BDNF ...

Synaptotagmin-2, and -1, linked to neurotransmission impairment and vulnerability in Spinal Muscular Atrophy
(OXFORD UNIV PRESS, 2016)
Spinal muscular atrophy (SMA) is the most frequent genetic cause of infant mortality. The disease is characterized by progressive muscle weakness and paralysis of axial and proximal limb muscles. It is caused by homozygous ...

Smn-Deficiency Increases the Intrinsic Excitability of Motoneurons
(2017-09-05)
During development, motoneurons experience significant changes in their size and in the number and strength of connections that they receive, which requires adaptive changes in their passive and active electrical properties. ...
