Trafficking of ampa receptors
SpletAMPA receptors (AMPARs) mediate the majority of fast excitatory synaptic transmission in the brain. Dynamic changes in neuronal synaptic efficacy, termed synaptic plasticity, … SpletHowever, recent evidence suggests that AMPA ( α -amino-3-hydroxyl-5-methyl-4-isoxayolepropionic acid)-type ligand-gated glutamate receptors are continuously recycling between the plasma membrane and the intracellular compartments via vesicle-mediated plasma membrane insertion and clathrin-dependent endocytosis.

SpletFurthermore, AMPA receptors co-assemble with auxiliary proteins which decorate the periphery of the receptor, thereby influencing the assembly [23–26], trafficking [27–30], and kinetic properties [18, 30–32] of the receptor complexes. Splet05. nov. 2010 · AMPA receptors (AMPARs) are tetramers composed of GluA1-4 (GluR1-4 or GluRA-D) subunits, and mediate the majority of fast excitatory synaptic transmission in the brain (1, 2). The dynamic regulation of AMPAR trafficking into and out of synapses is a major mechanism underlying synaptic plasticity (3–6).
SpletSince perturbation of DA-AMPA receptor interaction might sustain pathological conditions, the major aim of our work was to evaluate the effect of the hyperactive DA system on the AMPA subunit composition, trafficking, and membrane localization in the prefrontal cortex (PFC). ... overactivity reduced the translation of cortical AMPA receptors ...
