Neuregulin-1 is concentrated in the postsynaptic subsurface cistern of C-bouton inputs to α-motoneurons and altered during motoneuron diseases.

• Xavier Gallart-Palau, Olga Tarabal, +6 authors Josep E. Esquerda
• FASEB journal : official publication of the…
• 2014

C boutons are large, cholinergic, synaptic terminals that arise from local interneurons and specifically contact spinal α-motoneurons (MNs). C boutons characteristically display a postsynaptic… (More)

Mechanisms involved in spinal cord central synapse loss in a mouse model of spinal muscular atrophy.

• Olga Tarabal, Víctor Caraballo-Miralles, +5 authors Jordi Calderó
• Journal of neuropathology and experimental…
• 2014

Motoneuron (MN) cell death is the histopathologic hallmark of spinal muscular atrophy (SMA), although MN loss seems to be a late event. Conversely, disruption of afferent synapses on MNs has been… (More)

Lithium prevents excitotoxic cell death of motoneurons in organotypic slice cultures of spinal cord

• Jordi Calderó, Núria Molist Brunet, +4 authors Josep E. Esquerda

Several studies have reported the neuroprotective effects of lithium (Li) suggesting its potential in the treatment of neurological disorders, among of them amyotrophic lateral sclerosis (ALS).… (More)

Strong P2X4 purinergic receptor-like immunoreactivity is selectively associated with degenerating neurons in transgenic rodent models of amyotrophic lateral sclerosis.

Acute administration of a single dose of NMDA on embryonic day (E) 7 or later induces a marked excitotoxic injury in the chick spinal cord, including massive necrotic motoneuron (MN) death. When the… (More)

Regulation of motoneuronal calcitonin gene-related peptide (CGRP) during axonal growth and neuromuscular synaptic plasticity induced by botulinum toxin in rats.

• Olga Tarabal, Jordi Calderó, +4 authors Josep E. Esquerda
• The European journal of neuroscience
• 1996

The aim of this study was to examine whether changes in rat motoneuronal calcitonin gene-related peptide (CGRP) can be correlated with axonal growth and plasticity of neuromuscular synapses. Nerve… (More)

Neurotoxic species of misfolded SOD1G93A recognized by antibodies against the P2X4 subunit of the ATP receptor accumulate in damaged neurons of transgenic animal models of amyotrophic lateral…

In the chick embryo, in ovo application of NMDA from embryonic day (E) 5 to E9 results in selective damage to spinal cord motoneurons (MNs) that undergo a long-lasting degenerative process without… (More)

Intramuscular nerve sprouting induced by CNTF is associated with increases in CGRP content in mouse motor nerve terminals

• Olga Tarabal, Jordi Calderó, Josep E. Esquerda
• Neuroscience Letters
• 1996

It is known that motor nerve terminal sprouting induced by either nerve injury or muscle paralysis is associated with an increase in calcitonin gene-related peptide (CGRP) content in the soma of… (More)
