Long-Term Potentiation of Neuronal Glutamate Transporters
Persistent, use-dependent modulation of synaptic strength has been demonstrated for fast synaptic transmission mediated by glutamate and has been hypothesized to underlie persistent behavioral changes ranging from memory to addiction. Glutamate released at synapses is sequestered by the action of excitatory amino acid transporters (EAATs) in glia and postsynaptic neurons. So, the efficacy of gl...
متن کاملP19: Long-Term Potentiation
The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulations. Differe...
متن کاملP6: Metabotropic Glutamate Receptor-Dependent Role in the Formation of Long-Term Potentiation
Long-term potentiation (LTP) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. The first clue of the potential role of glutamate receptors in LTP was in 1991 with the observation that the mGluR agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (ACPD), increased LTP. Studies have shown that ACPD induc...
متن کاملNeuronal Glutamate Transporters Control Activation of Postsynaptic Metabotropic Glutamate Receptors and Influence Cerebellar Long-Term Depression
Neuronal and glial isoforms of glutamate transporters show distinct distributions on membranes surrounding excitatory synapses, but specific roles for transporter subtypes remain unidentified. At parallel fiber (PF) synapses in cerebellum, neuronal glutamate transporters and metabotropic glutamate receptors (mGluRs) have overlapping postsynaptic distributions suggesting that postsynaptic transp...
متن کاملP18: Signaling Pathway in Long-Term Potentiation
Synaptic plasticity in the central nervous system (CNS) of mammals has been discussed for many years. Several forms of synaptic plasticity of mammal’s CNS have been identified, such as those that occur in long-term potentiation (LTP). Different types of LTP have been observed in distinctive areas of the CNS of mammals. The hippocampus is one of the most important areas in the CNS that pla...
