Abstract:
'Excitotoxicity' represents the excitatory amino acid mediated degeneration of neurons. Glutamate is the major excitatory neurotransmitter in the brain. Glutamate excitotoxicity has been implicated in a number of neurodegenerative disorders like Stroke, Epilepsy, Alzheimer's disease and traumatic brain injury. This neurotoxicity is summed up by the 'glutamate hypothesis' which describes the cause of neuronal cell death as an excessive release of glutamate causing over excitation of the glutamate receptors and subsequent increase in influx of calcium leading to cell death.

Abstract:
Stroke is a leading cause of death. The majority are ischemic strokes resulting from acute focal brain infarction with sudden and persisting neurological deficits. This primary brain damage is followed by more substantial secondary destruction of surrounding areas (=penumbra). A major pathomechanism underlying penumbra formation is excitotoxicity, which results from over-excitation of glutaminergic synapses involving N-methyl-D-aspartate receptor signaling. Excitotoxicity also contributes to neurodegeneration in Alzheimer’s disease (AD), where the microtubule-associated protein tau deposits in

Studying the mechanisms underlying glutamate excitotoxicity and inflammatory responses provides hints to the pathology of neurological diseases such as epilepsy.

Abstract:
NMDA receptors are glutamate-gated cation channels named after their prototypical selective agonist NMDA. The channels occur as multiple subtypes, which are formed from interactions between different receptor subunits. NMDA receptor subunits are classified into three families: NR1, NR2A-D, and NR3A, B. NMDA receptors are implicated in HD pathology. During HD, a subset of medium-sized aspiny interneurons in the striatum that co-localize SST, NPY, and the enzyme NOS are selectively spared. In contrast, medium-sized spiny cells that constitute 80 % of all striatal neurons undergo selective

Mitochondrial Ca2+ buffering is an important physiological modulator of neuronal signaling and bioenergetics, but this propensity toward Ca2+ regulation proves pathological during excitotoxic insult.

This mitochondrial toxicity and Ca2+ dyshomeostasis may be visualized in real time as delayed calcium deregulation (DCD). DCD is a predictor of neuronal, excitoxic death

This Ca2+ influx acts as a secondary messenger to mediate neurodevelopment, synaptic plasticity, neuroprotection and neurodegeneration. The biological outcome of NMDAR activation is determined by a complicated interrelationship between the concentration of Ca2+ influx, NMDAR location (synaptic vs. extrasynaptic) as well as the subtype of the GluN2 subunit.
