Neurons on amoebae

open access: yesJournal of Symbolic Computation, 2023
We apply methods of machine-learning, such as neural networks, manifold learning and image processing, in order to study 2-dimensional amoebae in algebraic geometry and string theory. With the help of embedding manifold projection, we recover complicated conditions obtained from so-called lopsidedness.

Neuronal Polarity [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2009
The assembly of functional neuronal networks in the developing animal relies on the polarization of neurons, i.e., the formation of a single axon and multiple dendrites. Breaking the symmetry of neurons depends on cytoskeletal rearrangements. In particular, axon specification requires local dynamic instability of actin and stabilization of microtubules.

Pharmacological inhibition of HDAC6 improves muscle phenotypes in dystrophin-deficient mice by downregulating TGF-β via Smad3 acetylation

open access: yesNature Communications, 2022
Here, authors show that Smad3 acetylation via HDAC6 inhibition reverses Duchenne muscular dystrophy-like symptoms in the mdx mouse model, suggesting a potential therapeutic target for the disorder.

Characterization of excitatory synaptic transmission in the anterior cingulate cortex of adult tree shrew

open access: yesMolecular Brain, 2017
The tree shrew, as a primate-like animal model, has been used for studying high brain functions such as social emotion and spatial learning memory. However, little is known about the excitatory synaptic transmission in cortical brain areas of the tree ...

Ascending noradrenergic excitation from the locus coeruleus to the anterior cingulate cortex

open access: yesMolecular Brain, 2020
Anterior cingulate cortex (ACC) plays important roles in sensory perception including pain and itch. Neurons in the ACC receive various neuromodulatory inputs from subcortical structures, including locus coeruleus noradrenaline (LC-NA) neurons.

Microvascular decompression for hemifacial spasm: a review of twenty-one operated cases

open access: yesThe Egyptian Journal of Neurology, Psychiatry and Neurosurgery, 2020
Background Microvascular decompression of facial nerve provides definitive and long-term cure for hemifacial spasm. We review our experience of treating hemifacial spasm by microvascular decompression.

A Stem Cell Model of the Motor Circuit Uncouples Motor Neuron Death from Hyperexcitability Induced by SMN Deficiency

open access: yesCell Reports, 2016
In spinal muscular atrophy, a neurodegenerative disease caused by ubiquitous deficiency in the survival motor neuron (SMN) protein, sensory-motor synaptic dysfunction and increased excitability precede motor neuron (MN) loss.

Foetal neural progenitors contribute to postnatal circuits formation ex vivo: an electrophysiological investigation

open access: yesMolecular Brain, 2020
Neuronal progenitor cells (NPC) play an essential role in homeostasis of the central nervous system (CNS). Considering their ability to differentiate into specific lineages, their manipulation and control could have a major therapeutic impact for those ...

C9orf72-ALS human iPSC microglia are pro-inflammatory and toxic to co-cultured motor neurons via MMP9

open access: yesNature Communications, 2023
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive motor neuron loss, with additional pathophysiological involvement of non-neuronal cells such as microglia.
