Synaptic Plasticity and Cognitive Function in RASopathies

Summary

The project is targeting cognitive impairment, one of the main health problems of patients with RAS pathway disorders. The aim of this study is to translate findings of animal studies to humans. This has been done by the applicants successfully for Lovastatin in Nf1. This result will be transferred to patients with Noonan Syndrome. lamotrigine is most likely a more effective and promising substance improving synaptic plasticity and consecutive cognitive function. It is expected that both substances are improving synaptic plasticity as well as alertness and changes in alertness may be a precondition for improvement of cognition.

Does rTMS Induce Synaptic Plasticity?

The purpose of this study is to utilize the radioactive positron emission tomography (PET) tracer [11C]UCB-J to investigate the effect of repetitive transcranial magnetic stimulation (rTMS...

Role of Slow-wave Activity and Plasticity in MDD

The hypothesis underlying this proposal is that deficits of synaptic plasticity underlie the slow-wave activity (SWA) abnormalities observed n major depressive disorder (MDD), and that man...

Ketamine Treatment Effects on Synaptic Plasticity in Depression

Depression is the leading cause of disability globally (1, 2). One-third to one-half of patients suffering from major depressive disorder (MDD) do not achieve remission even after multiple...

A Study of the Proper Dosage of Lovastatin and Docetaxel for Patients With Cancer

This purpose of this study is to evaluate the use of two medications, docetaxel and lovastatin. There are two phases. Subjects in Phase I can have any cancer. This phase will determine ...

Imaging Synaptic Density in Cocaine and Opiate Addiction In Vivo Using 11UCB-J PET

This study aims to measure synaptic density in the brains (including in ventral striatum [VS] and medial prefrontal cortex [mPFC]) of abstinent subjects with Cocaine Use Disorder (CUD) or ...

Grape-derived polyphenols ameliorate stress-induced depression by regulating synaptic plasticity.

Major depressive disorder (MDD) is associated with stress-induced immune dysregulation and reduced Brain Derived Neurotrophic Factor (BDNF) levels in sensitive brain regions associated with depression...

Energy efficient synaptic plasticity.

Many aspects of the brain's design can be understood as the result of evolutionary drive towards metabolic efficiency. In addition to the energetic costs of neural computation and transmission, experi...

RCAN1 Regulates Bidirectional Synaptic Plasticity.

Synaptic plasticity, with its two most studied forms, long-term potentiation (LTP) and long-term depression (LTD), is the cellular mechanism underlying learning and memory. Although it has been known ...

The contribution of ion channels in input-output plasticity.

Persistent changes that occur in brain circuits are classically thought to be mediated by long-term modifications in synaptic efficacy. Yet, many studies have shown that voltage-gated ion channels loc...

Linking NMDA Receptor Synaptic Retention to Synaptic Plasticity and Cognition.

NMDA receptor (NMDAR) subunit composition plays a pivotal role in synaptic plasticity at excitatory synapses. Still, the mechanisms responsible for the synaptic retention of NMDARs following induction...

Medical and Biotech [MESH] Definitions

A neuronal protein consisting of three PDZ DOMAINS, an SH3 DOMAIN, and a C-terminal guanylate kinase-like region (see MAGUK PROTEINS). It localizes to the POST-SYNAPTIC DENSITY and associates with the cytoplasmic tail of NMDA RECEPTORS and SHAKER POTASSIUM CHANNELS, playing a critical role in NMDA receptor-mediated SYNAPTIC PLASTICITY.

Cytoskeleton specialization at the cytoplasmic side of postsynaptic membrane in SYNAPSES. It is involved in neuronal signaling and NEURONAL PLASTICITY and comprised of GLUTAMATE RECEPTORS; scaffolding molecules (e.g., PSD95, PSD93), and other proteins (e.g., CaCMKII).

The communication from a NEURON to a target (neuron, muscle, or secretory cell) across a SYNAPSE. In chemical synaptic transmission, the presynaptic neuron releases a NEUROTRANSMITTER that diffuses across the synaptic cleft and binds to specific synaptic receptors, activating them. The activated receptors modulate specific ion channels and/or second-messenger systems in the postsynaptic cell. In electrical synaptic transmission, electrical signals are communicated as an ionic current flow across ELECTRICAL SYNAPSES.

Serine/threonine protein kinase responsible for various SKELETAL MUSCLE functions; HEART CONDUCTION SYSTEM activity; calcium HOMEOSTASIS; calcium uptake by SARCOPLASMIC RETICULUM and SYNAPTIC PLASTICITY. It is encoded by the DMPK gene and its abnormal EXPANDED TRINUCLEOTIDE REPEAT of CTG in the 3'-UTR is associated with MYOTONIC DYSTROPHY 1.

The voltages across pre- or post-SYNAPTIC MEMBRANES.
