Gating modes in AMPA receptors.
AMPA receptors are ligand-gated ion channels that show multiple conductance levels, indicating that gating of individual AMPA subunits is to some extent independent of the other subunits. To study AMPAR subunit interactions during activation gating, we recorded from single channels in the absence of channel block and desensitization and at negative and positive membrane potentials. In saturatin...
متن کاملNomadic 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 کاملCalcium-Permeable AMPA Receptors in the Retina
The retina transforms light entering the eye into a sophisticated neural representation of our visual world. Specialized synapses, cells, and circuits in the retina have evolved to encode luminance, contrast, motion, and other complex visual features. Although a great deal has been learned about the cellular morphology and circuitry that underlies this image processing, many of the synapses in ...
متن کاملAmpa and Kainate Receptors in Cns Injury*
Glutamate receptors are the most common excitatory neurotransmitter receptors in the central nervous system (CNS). Excessive stimulation of glutamate receptors, including receptors of the AMPA and kainate families, is believed to contribute to the neurodegeneration encountered in stroke, CNS trauma, and several degenerative neurologic disorders. Animal models also suggest that AMPA and kainate ...
متن کاملExtensive phosphorylation of AMPA receptors in neurons.
Regulation of AMPA receptor (AMPAR) function is a fundamental mechanism controlling synaptic strength during long-term potentiation/depression and homeostatic scaling. AMPAR function and membrane trafficking is controlled by protein-protein interactions, as well as by posttranslational modifications. Phosphorylation of the GluA1 AMPAR subunit at S845 and S831 play especially important roles dur...
