NO signalling in synaptic transmission [PDF]

BMC Pharmacology, 2011
Background The NO/cGMP signaling cascade has been proposed to play a role in long-term potentiation (LTP) and the modulation of synaptic transmission. Nitric oxide is formed enzymatically by NO synthases (NOS); two NOS, the endothelial and neuronal isoform (eNOS, nNOS) produce NO as a signalling molecule.

Reprogramming glioblastoma multiforme cells into neurons by protein kinase inhibitors

Journal of Experimental & Clinical Cancer Research, 2018
Background Reprogramming of cancers into normal-like tissues is an innovative strategy for cancer treatment. Recent reports demonstrate that defined factors can reprogram cancer cells into pluripotent stem cells. Glioblastoma multiforme (GBM) is the most

Noradrenaline depresses facial stimulation-evoked cerebellar MLI-PC synaptic transmission via α2-AR/PKA signaling cascade in vivo in mice

Scientific Reports, 2023
The noradrenergic fibers of the locus coeruleus, together with mossy fibers and climbing fibers, comprise the three types of cerebellar afferents that modulate the cerebellar neuronal circuit.

Conversion of Fibroblasts to Neural Cells by p53 Depletion

Cell Reports, 2014
Conversion from fibroblasts to neurons has recently been successfully induced. However, the underlying mechanisms are poorly understood. Here, we find that depletion of p53 alone converts fibroblasts into all three major neural lineages.

Differential synaptic mechanism underlying the neuronal modulation of prefrontal cortex, amygdala, and hippocampus in response to chronic postsurgical pain with or without cognitive deficits in rats

Frontiers in Molecular Neuroscience, 2022
Chronic Postsurgical Pain (CPSP) is well recognized to impair cognition, particularly memory. Mounting evidence suggests anatomic and mechanistic overlap between pain and cognition on several levels.

Secreted amyloid-β precursor protein functions as a GABABR1a ligand to modulate synaptic transmission

Science, 2019
A physiological function for sAPP? Although the pathological role of the amyloid-β precursor protein (APP) in Alzheimer's disease is well studied, the physiological role of this protein has remained elusive. Rice et al. found that the secreted ectodomain

Membrane palmitoylated protein 2 is a synaptic scaffold protein required for synaptic SK2-containing channel function

eLife, 2016
Mouse CA1 pyramidal neurons express apamin-sensitive SK2-containing channels in the post-synaptic membrane, positioned close to NMDA-type (N-methyl-D-aspartate) glutamate receptors.

Photons guided by axons may enable backpropagation-based learning in the brain [PDF]

Sci Rep 12, 20720 (2022), 2022
Despite great advances in explaining synaptic plasticity and neuron function, a complete understanding of the brain's learning algorithms is still missing. Artificial neural networks provide a powerful learning paradigm through the backpropagation algorithm which modifies synaptic weights by using feedback connections.

Amyloid-β acts as a regulator of neurotransmitter release disrupting the interaction between synaptophysin and VAMP2. [PDF]

, 2012
BACKGROUND: It is becoming increasingly evident that deficits in the cortex and hippocampus at early stages of dementia in Alzheimer's disease (AD) are associated with synaptic damage caused by oligomers of the toxic amyloid-β peptide (Aβ42).

Oxytocin Regulates Synaptic Transmission in the Sensory Cortices in a Developmentally Dynamic Manner

Frontiers in Cellular Neuroscience, 2021
The development and stabilization of neuronal circuits are critical to proper brain function. Synapses are the building blocks of neural circuits. Here we examine the effects of the neuropeptide oxytocin on synaptic transmission in L2/3 pyramidal neurons
