Category: Cellular Component. Interneurons receive strong excitatory innervation from glutamatergic neurons and it has been much debated whether these synapses show mechanisms of Author(s): Scott, John Thomas | Advisor(s): Zou, Yimin | Abstract: Glutamatergic synapses are the main excitatory synapses in the mammalian central nervous The first glutamatergic transmission is mediated only by N-methyl-D-aspartate ( NMDA) receptors and is silent at resting potentials. More mature synapses acquire Glutamate is packaged into synaptic vesicles in the presynaptic terminal. Once released into the synaptic cleft, glutamate acts on postsynaptic ionotropic glutamate Glutamate receptors are located in both neurons and glial cells throughout the CNS.

However, it is not clear if the same Both Aβ and tau alter synaptic plasticity, leading to synapse loss, neural network dysfunction, and eventually neuron loss.

Glutamatergic neurons produce glutamate, which is one of the most common excitatory neurotransmitters in the central nervous system (CNS). It plays a critical role in fundamental processes, such as learning, cognition, and memory, and dysregulation of glutamatergic transmission can result in several neurological conditions.

Impaired synaptic plasticity and dendritic loss in excitatory glutamatergic synapses are early events in Alzheimer disease (AD). These synaptic abnormalities are triggered by accumulation of soluble fibrillary β-amyloid (Aβ) oligomers, which bind to several postsynaptic and presynaptic partners. Normal transmission across a glutamatergic synapse relies on the neurotransmitter glutamate, the glutamate-specific AMPA receptor (AMPAR), and calcium ions.

Although many of these proteins have been identified, the roles they play in generating functional connections during development remain unknown.

Mobile genetic elements from the human endogenous retrovirus (HERV) families also have the capacity to control gene regulatory networks during brain evolution and development ( 1 , 7 , 8 ) and modulate brain cell physiology and communication ( 3 ).

Glutamate is the primary excitatory transmitter in adult brain, acting through synapses on dendritic spines and shafts. When dopaminergic neurons make synapses on spiny neurons of the striatum nucleus, they tune the responsiveness of glutamatergic synapses by means of the dopamine D1 and D2 receptors.

Glutamatergic Synapse Glutamatergic synapses are thought to be sites of memory consolidation and storage, and well-known synaptic plasticity mechanisms – mediated by NMDA and mGluR receptors at these synapses – are thought to participate in important ways in learning and the formation of memories.

An overview of the glutamatergic synapse pathway, involving receptors, channels and neurotransmitter transporters. Glutamatergic excitotoxicity may also induce long-term changes in basal and activity-dependent IEG expression following such an insult (Barker-Haliski et al. 2012).

These neurogliomal synapses show a typical synaptic ultrastructure, are located on tumour microtubes, and produce postsynaptic currents that are mediated by glutamate receptors of the AMPA subtype.

These findings support the hypothesis that HERV genetic elements represent a putative substrate in psychotic disorders, linking the well- defined immune and synaptic dysfunctions observed in mental illnesses. Antiseizure Effects Found with the Overexpression of SLC1A2 via the Glutamatergic Synapse Pathway. NMDARs play an important role in the glutamatergic synapse pathway and have been associated with the inactivation of GLU through regulating the concentration of calcium, magnesium, zinc ions, and other inside and outside the membrane. Collectively, these data demonstrate the role of the fast-acting glutamatergic synapse in the regulation of AgRP neuronal activity and functional output over long periods of time. Liu et al.
