CaMKII Triggers the Diffusional Trapping of Surface AMPARs through Phosphorylation of Stargazin [PDF]
The Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) is critically required for the synaptic recruitment of AMPA-type glutamate receptors (AMPARs) during both development and plasticity. However, the underlying mechanism is unknown. Using single-particle tracking of AMPARs, we show that CaMKII activation and postsynaptic translocation induce the ...

A sex difference in the response of the rodent postsynaptic density to synGAP haploinsufficiency [PDF]
SynGAP is a postsynaptic density (PSD) protein that binds to PDZ domains of the scaffold protein PSD-95. We previously reported that heterozygous deletion of Syngap1 in mice is correlated with increased steady-state levels of other key PSD proteins that ...

The malleable brain: plasticity of neural circuits and behavior: A review from students to students [PDF]
One of the most intriguing features of the brain is its ability to be malleable, allowing it to adapt continually to changes in the environment. Specific neuronal activity patterns drive long-lasting increases or decreases in the strength of synaptic ...

S-nitrosylation of stargazin regulates surface expression of AMPA-glutamate neurotransmitter receptors [PDF]
Synaptic plasticity is mediated by changes in the surface expression of AMPA receptors (AMPARs). Stargazin and related transmembrane AMPAR regulatory proteins have emerged as the principal regulators of AMPAR surface expression. Here, we show in heterologous cells and primary neurons that stargazin is physiologically S-nitrosylated, resulting in ...

Protein kinase C regulates AMPA receptor auxiliary protein Shisa9/CKAMP44 through interactions with neuronal scaffold PICK1 [PDF]
Synaptic α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate (AMPA) receptors are essential mediators of neurotransmission in the central nervous system. Shisa9/cysteine-knot AMPAR modulating protein 44 (CKAMP44) is a transmembrane protein recently found ...

Postsynaptic density 95 controls AMPA receptor incorporation during long-term potentiation and experience-driven synaptic plasticity [PDF]
The regulated delivery of AMPA-type glutamate receptors (AMPARs) to synapses is an important mechanism underlying synaptic plasticity. Here, we ask whether the synaptic scaffolding protein PSD-95 (postsynaptic density 95) participates in AMPAR ...

S-nitrosation and neuronal plasticity [PDF]
Nitric oxide (NO) has long been recognized as a multifaceted participant in brain physiology. Despite the knowledge that was gathered over many years regarding the contribution of NO to neuronal plasticity, for example the ability of the brain to change ...

Synaptic nanomodules underlie the organization and plasticity of spine synapses. [PDF]
Experience results in long-lasting changes in dendritic spine size, yet how the molecular architecture of the synapse responds to plasticity remains poorly understood. Here a combined approach of multicolor stimulated emission depletion microscopy (STED)

Synaptic Plasticity and Memory: New Insights from Hippocampal Left-Right Asymmetries. [PDF]
All synapses are not the same. They differ in their morphology, molecular constituents, and malleability. A striking left-right asymmetry in the distribution of different types of synapse was recently uncovered at the CA3-CA1 projection in the mouse ...
