Wnt Signaling: Role in Alzheimer Disease and Schizophrenia

…, C Montecinos-Oliva, M Fuenzalida - Journal of Neuroimmune …, 2012 - Springer
Wnt signaling function starts during the development of the nervous system and is crucial for
synaptic plasticity in the adult brain. Clearly Wnt effects in synaptic and plastic processes …

Activity-dependent switch of GABAergic inhibition into glutamatergic excitation in astrocyte-neuron networks

…, R Quintana, A Rayan, A Díez, M Fuenzalida… - Elife, 2016 - elifesciences.org
10.7554/eLife.20362.001 Interneurons are critical for proper neural network function and
can activate Ca 2+ signaling in astrocytes. However, the impact of the interneuron-astrocyte …

In vivo activation of Wnt signaling pathway enhances cognitive function of adult mice and reverses cognitive deficits in an Alzheimer's disease model

JY Vargas, M Fuenzalida… - Journal of Neuroscience, 2014 - Soc Neuroscience
The role of the Wnt signaling pathway during synaptic development has been well established.
In the adult brain, different components of Wnt signaling are expressed, but little is known …

[HTML][HTML] Wnt-5aoccludes Aβ oligomer-induced depression of glutamatergic transmission in hippocampal neurons

W Cerpa, GG Farías, JA Godoy, M Fuenzalida… - Molecular …, 2010 - Springer
Background Soluble amyloid-β (Aβ;) oligomers have been recognized to be early and key
intermediates in Alzheimer's disease (AD)-related synaptic dysfunction. Aβ oligomers block …

Wnt-5a modulates recycling of functional GABAA receptors on hippocampal neurons

…, A Couve, C Bonansco, M Fuenzalida… - Journal of …, 2010 - Soc Neuroscience
GABA A receptors (GABA A -Rs) play a significant role in mediating fast synaptic inhibition
and it is the main inhibitory receptor in the CNS. The role of Wnt signaling in coordinating …

Glutamate released spontaneously from astrocytes sets the threshold for synaptic plasticity

…, M Roncagliolo, M Fuenzalida - European Journal of …, 2011 - Wiley Online Library
Astrocytes exhibit spontaneous calcium oscillations that could induce the release of
glutamate as gliotransmitter in rat hippocampal slices. However, it is unknown whether this …

Epigenetic editing of the Dlg4/PSD95 gene improves cognition in aged and Alzheimer's disease mice

…, RL Neve, NC Inestrosa, U Wyneken, M Fuenzalida… - Brain, 2017 - academic.oup.com
The Dlg4 gene encodes for post-synaptic density protein 95 (PSD95), a major synaptic protein
that clusters glutamate receptors and is critical for plasticity. PSD95 levels are diminished …

[HTML][HTML] Plasticity of hippocampal excitatory-inhibitory balance: missing the synaptic control in the epileptic brain

C Bonansco, M Fuenzalida - Neural plasticity, 2016 - hindawi.com
Synaptic plasticity is the capacity generated by experience to modify the neural function and,
thereby, adapt our behaviour. Long-term plasticity of glutamatergic and GABAergic …

[HTML][HTML] Pannexin 1 regulates bidirectional hippocampal synaptic plasticity in adult mice

…, AG Palacios, P Muñoz, M Fuenzalida… - Frontiers in cellular …, 2014 - frontiersin.org
The threshold for bidirectional modification of synaptic plasticity is known to be controlled by
several factors, including the balance between protein phosphorylation and …

Coordinated prefrontal–hippocampal activity and navigation strategy-related prefrontal firing during spatial memory formation

…, M Aguilar-Rivera, M Fuenzalida… - Proceedings of the …, 2018 - National Acad Sciences
Learning the location of relevant places in the environment is crucial for survival. Such capacity
is supported by a distributed network comprising the prefrontal cortex and hippocampus, …
