Effect of hypoxia on lung gene expression and proteomic profile: insights into the pulmonary surfactant response
(Elsevier, 2014)
Exposure of lung to hypoxia has been previously reported to be associated with significant alterations in the protein content of bronchoalveolar lavage (BAL) and lung tissue. In the present work we have used a proteomic ...

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 ...

The carotid body, a neurogenic niche in the adult peripheral nervous system
(Univ pisa, 2010)
We have described a new population of adult neural stem cells residing in the carotid body, a chemoreceptor organ in the peripheral nervous system. These progenitor cells support neurogenesis in vivo in response to ...

A New Role for Myosin II in Vesicle Fission
(Public Library of Science, 2014-06-24)
An endocytic vesicle is formed from a flat plasma membrane patch by a sequential process of invagination, bud formation and fission. The scission step requires the formation of a tubular membrane neck (the fission pore) ...

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 ...

Neurexin Dysfunction in Adult Neurons Results in Autistic-like Behavior in Mice
(Cell Press, 2014)
Autism spectrum disorders (ASDs) comprise a group of clinical phenotypes characterized by repetitive behavior and social and communication deficits. Autism is generally viewed as a neurodevelopmental disorder where insults ...
