Nomadic AMPA Receptors and LTP
leased glutamate could explain the electrophysiological changes observed during LTP that have been attributed to an increase in presynaptically released neurotrans-Long-term potentiation (LTP) is one of the most widely mitters. In support of the silent synapse hypothesis, studied topics in neuroscience today. LTP refers to a electrophysiological and immunohistochemical studies long-lasting incr...
متن کاملRecycling endosomes supply AMPA receptors for LTP.
Long-term potentiation (LTP) of synaptic strength, the most established cellular model of information storage in the brain, is expressed by an increase in the number of postsynaptic AMPA receptors. However, the source of AMPA receptors mobilized during LTP is unknown. We report that AMPA receptors are transported from recycling endosomes to the plasma membrane for LTP. Stimuli that triggered LT...
متن کاملDriving AMPA receptors into synapses by LTP and CaMKII: requirement for GluR1 and PDZ domain interaction.
To elucidate mechanisms that control and execute activity-dependent synaptic plasticity, alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate receptors (AMPA-Rs) with an electrophysiological tag were expressed in rat hippocampal neurons. Long-term potentiation (LTP) or increased activity of the calcium/calmodulin-dependent protein kinase II (CaMKII) induced delivery of tagged AMPA-Rs into syna...
متن کاملContribution of AMPA and NMDA receptors to early and late phases of LTP in hippocampal slices.
Alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) and N-methyl-D-aspartate (NMDA) receptor mediated responses were investigated in rat hippocampal slices under 4h of long-term potentiation (LTP) expression. A modified medium containing the NMDA receptor antagonist AP5 and low concentration of Mg(2+) was used to monitor isolated AMPA responses. NMDA components were determined from...
متن کاملAge-dependent requirement of AKAP150-anchored PKA and GluR2-lacking AMPA receptors in LTP.
Association of PKA with the AMPA receptor GluR1 subunit via the A kinase anchor protein AKAP150 is crucial for GluR1 phosphorylation. Mutating the AKAP150 gene to specifically prevent PKA binding reduced PKA within postsynaptic densities (>70%). It abolished hippocampal LTP in 7-12 but not 4-week-old mice. Inhibitors of PKA and of GluR2-lacking AMPA receptors blocked single tetanus LTP in hippo...
