چکیده

Glial cells throughout the nervous system are closely associated with synapses. Accompanying these anatomical couplings are intriguing functional interactions, including the capacity of certain glial cells to respond to and modulate neurotransmission. Glial cells can also help establish, maintain, and reconstitute synapses. In this review, we discuss evidence indicating that glial cells make important contributions to synaptic function.

نقش سلول های گلیا در پاسخ سیناپسی پایه و شکل پذیری سیناپسی کوتاه مدت ناحیه CA1 هیپوکمپ

Background and purpose: Glial cells seem to play role in synaptic plasticity because they have the ability to release trophic factors and gliotransmitters and respond to neurotransmitters. They also play important role in synaptic space homeostasis. In this study, the role of hippocampal glial cells in baseline synaptic response and short term synaptic plasticity were investigated.  Material...

Tripartite synapses: glia, the unacknowledged partner.

According to the classical view of the nervous system, the numerically superior glial cells have inferior roles in that they provide an ideal environment for neuronal-cell function. However, there is a wave of new information suggesting that glia are intimately involved in the active control of neuronal activity and synaptic neurotransmission. Recent evidence shows that glia respond to neuronal...

Possible Effects of Synaptic Imbalances on Oligodendrocyte–Axonic Interactions in Schizophrenia: A Hypothetical Model

A model of glial-neuronal interactions is proposed that could be explanatory for the demyelination identified in brains with schizophrenia. It is based on two hypotheses: (1) that glia-neuron systems are functionally viable and important for normal brain function, and (2) that disruption of this postulated function disturbs the glial categorization function, as shown by formal analysis. Accordi...

The Glia Connection of the Glutamate/Glutamine Shuttle

Problem statement: Glia cells outnumber neurons but their role in synaptic transmission is still matter of debate. The recycling of Glutamate, the main excitatory neurotransmitter, carried out by the glutamate/glutamine shuttle, requires the involvement of glia, suggesting their involvement in neurotransmission. Approach: This review focuses on novel functions of glia proteins involved in this ...

Novel Treatment Approach in Schizophrenia: Substitution of Glial Binding Proteins

In chronic schizophrenia, synaptic information processing is unbalanced, as shown in a model of glial-neuronal synaptic units, called tripartite synapses. The glial component of the synapse exerts a modifying function in neurotransmission since the astrocyte activated by neurotransmitters produces gliotransmitters that negatively feedback to the presynapse. It is hypothesized that in schizophre...
