Regulation of AMPA Receptors by Phosphorylation [PDF]
The AMPA receptors for glutamate are oligomeric structures that mediate fast excitatory responses in the central nervous system. Phosphorylation of AMPA receptors is an important mechanism for short-term modulation of their function, and is thought to play an important role in synaptic plasticity in different brain regions.

Stargazin Modulation of AMPA Receptors [PDF]
Fast excitatory synaptic signaling in the mammalian brain is mediated by AMPA-type ionotropic glutamate receptors. In neurons, AMPA receptors co-assemble with auxiliary proteins, such as stargazin, which can markedly alter receptor trafficking and gating.

Auxiliary subunits keep AMPA receptors compact during activation and desensitization
Signal transduction at vertebrate excitatory synapses involves the rapid activation of AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionate) receptors, glutamate-gated ion channels whose four subunits assemble as a dimer-of-dimers.

Regulation of AMPA receptors in spinal nociception
The functional properties of α-amino-3-hydroxy-5-methy-4-isoxazole propionate (AMPA) receptors in different brain regions, such as hippocampus and cerebellum, have been well studied in vitro and in vivo. The AMPA receptors present a unique characteristic

Early Developmental Neuronal Activity Impacts Oligodendrocyte Differentiation Through AMPA Receptors. [PDF]
In early brain development, neuronal activity reduces OPC differentiation. Decreased neuronal activity changes oligodendrocyte gene expression, including upregulating glutamate receptor genes. AMPA signaling regulates the final stages of OPC differentiation.

Synaptic and axonal glutamatergic signaling to NG2 glia in white matter is critical for the cells’ differentiation and activity dependent myelination. However, in gray matter the impact of neuron-to-NG2 glia signaling is still elusive, because most of ...

Testing of the therapeutic efficacy and safety of AMPA receptor RNA aptamers in an ALS mouse model
RNA aptamers designed to block AMPA receptors effectively reduce progression of motor dysfunction, improve TDP-43 pathology, and prevent death of motor neurons in AR2 mice, a mouse model of sporadic ALS, without adverse effects.

SAD-B modulates epileptic seizure by regulating AMPA receptors in patients with temporal lobe epilepsy and in the PTZ-induced epileptic model [PDF]
α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are the predominant mediators of glutamate-induced excitatory neurotransmission.

At CA1→subiculum synapses, alternatively spliced neurexin-1 (Nrxn1SS4+) and neurexin-3 (Nrxn3SS4+) enhance NMDA-receptors and suppress AMPA-receptors, respectively, without affecting synapse formation.
