Abstract:

D-Aspartate (D-Asp) is an endogenous compound found in the central nervous system (CNS) of a variety of organisms. Despite its prevalence, however, relatively little understood of its physiological role. The prevailing theory is that D-Asp is an alternate agonist of N-methyl-D-aspartate receptor (NMDAR) channels. The goal of this work was to characterize the currents activated by D-Asp in neurons Aplysia californica, focusing on cells of the buccal S cluster (BSC). First, a general electrophysiological characterization was carried out, examining ion permeability, agonist dose-response, and th

Abstract:

The non-invasive detection of neuronal transmission is of prime importance in order to understand brain function better. This will aid cognitive neuroscience, as well as medical science, in the early detection of diseased states. Herein, approaches to molecular imaging of the NMDA receptor, a receptor subtype of the excitatory neurotransmitter glutamate, through the use of targeted contrast agents, is described. Initially, a series of NMDA receptor-targeted MRI contrast agents was developed based upon a known competitive NMDA receptor antagonist, appended to an N-linked ‘Gd-DOTA’ core that pos

Abstract:

N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis is a recently described autoimmune encephalopathy defined by the presence of serum antibodies that bind NMDARs (NMDAR-Abs). NMDAR-Ab encephalitis is a severe, but treatmentresponsive encephalitis with subacute onset. It can be associated with tumours and affects mainly young adults. Patients present with cognitive dysfunction, seizures, psychiatric and sleep disorders and most develop dyskinesias, autonomic instability and reduced consciousness.

Abstract:

Synaptic N-Methyl-D-aspartate receptors (NMDARs) are crucial for neural coding and plasticity. However, little is known about the adaptive function of extrasynaptic NMDARs located on the dendritic shaft. Here we find that in CA1 pyramidal neurons backpropagating action potentials (bAPs) recruit shaft NMDARs exposed to ambient glutamate of non-vesicular origin. In contrast, spine NMDARs are "protected" under baseline conditions from such glutamate by perisynaptic transporters: bAP-evoked Ca2+ entry through these receptors can be detected upon synaptic glutamate release or local glutamate uncagi

Abstract:

Functional hyperemia is an endogenous regulatory process coupling synaptic activity and elevated neuronal energy demand with increased local blood flow. This involves signalling between neurons, astrocytes and blood vessels, comprising the neurovascular unit. Astrocyte processes ensheath both synapses and blood vessels, permitting multi-modal responses to synaptic activity, where astrocyte cytoplasmic Ca2+ is elevated, triggering endfeet processes to release vasoactive molecules, such as arachidonic acid (AA) metabolites and gliotransmitters, such as D-serine. D-Serine is a co-agonist of the

Alcohol affects many neurochemical processes, causing long-lasting changes in both the adult and developing brain.

The goal of this project was to define the effects of acute and subchronic ethanol exposure on the expression of proteins in the Jak-Stat pathway, using cultured NG108-15 cells, and in addition, to test the hypothesis that these effects are mediated through the NMDA recep

Abstract:

The aim of this thesis is to investigate the use of NMDAR antagonists in preventing naturopathic sensitisation. The chronic constriction injury (CCI) model of neuropathic pain is used to study the role of NMDARs in the development of neuropathic pain and subsequent modulation. Behavioural effects are assessed in association with changes in NMDAR subtypes. Memantine and ketamine (NMDAR antagonists) are shown to attenuate typical behavioural responses (thermal hyperalgesia and cold allodynia) to nerve injury. In addition, NMDAR antagonist pre-treatment is shown to effect the subsequent NMDAR sub

Evidence supports a role for neuronal damage arising from excessive activation of glutamate receptors (especially the NMDA subtype) in the pathogenesis of Huntington's disease (HD), although clinical trials involving NMDA receptor inhibition have mostly failed. Further understanding of the underlying molecular mechanisms is therefore needed to refine therapeutic approaches. My work has focused on the elucidation of molecular pathways linking huntingtin (htt) to NMDA receptors (NMDARs).

Abstract:

Due to its great importance in learning and memory, the hippocampus has received a lot of attention from studies investigating synaptic plasticity, the molecular correlates of learning and memory. Corticosterone (CaRT) is the endogenous glucocorticoid in rodents and is of high physiological significance to the organism. In response to stress the glucocorticoid concentration rises rapidly, releasing the hormone into the blood and allowing it to exert its actions on the level of the pituitary, the hypothalamus and the hippocampus. Interestingly, learning and memory are also subject to glucocorti

Regulation of NMDAR activity by desensitization is important in physiological and pathological states.

Abstract:

N-methyl-D-aspartate receptors (NMDAR) are ionotropic glutamate receptors which can be blocked by Mg2+ in a voltage-dependent manner and are highly permeable to Ca2+, hence they represent a medically relevant target for neurodegenerative disorders caused by excitotoxicity. The two main objectives of this study were, (i) to determine the impact of Q/R/N, +1 and -8 sites modification in the M2 pore region of GluN2A NMDAR subunit on Mg2+ block and other open channel blockers; and (ii) to evaluate novel multi-target-directed ligands (MTDL) for Alzheimer’s disease therapy.

Abstract:

N-methyl-D-aspartate receptors (NMDARs) are glutamate-gated ionotropic receptors. When activated, NMDARs let extracellular sodium and calcium ions enter neurons. This calcium influx, depending on its duration, intensity and the presence of nearby signalling proteins can signal to synaptic plasticity. Additionally, physiological NMDAR activity promotes pro-survival cascades and gene transcription, whereas both lack of activation and overactivation of these receptors trigger pro-death signals. Several neurodegenerative pathologies such as stroke/ischemia and Alzheimer’s disease are thought to in
