Visualizing Arc protein dynamics and localization in the mammalian brain using AAV-mediated in situ gene labeling [PDF]
The activity-regulated cytoskeleton-associated (Arc) protein is essential for synaptic plasticity and memory formation. The Arc gene, which contains remnants of a structural GAG retrotransposon sequence, produces a protein that self-assembles into capsid-

Stargazin Interaction With Serine Racemase Mediates Cerebral Ischemia/Reperfusion Injury in Rats [PDF]
D-Serine is thought to be involved in N-methyl-D-aspartate (NMDA)-type glutamate receptor-mediated neurotoxicity and plays a pathophysiologic role in stroke.

Notes on the History of In Vitro Hippocampal Electrophysiology and LTP: Personal Reflections. [PDF]
ABSTRACT This essay describes the development of the in vitro hippocampal slice technique and my small contributions to it and to influencing Roger Nicoll's early interests in the hippocampus and LTP. My Ph.D. work at Harvard with Timothy Teyler was on field potential studies of synaptic plasticity, including LTP, in the rat in vitro hippocampal slice.

Stargazin attenuates intracellular polyamine block of calcium-permeable AMPA receptors [PDF]
Endogenous polyamines profoundly affect the activity of various ion channels, including that of calcium-permeable AMPA-type glutamate receptors (CP-AMPARs). Here we show that stargazin, a transmembrane AMPAR regulatory protein (TARP) known to influence transport, gating and desensitization of AMPARs, greatly reduces block of CP-AMPARs by intracellular ...

Molecular physiology of Arc/Arg3.1: The oligomeric state hypothesis of synaptic plasticity. [PDF]
Abstract The immediate early gene, Arc, is a pivotal regulator of synaptic plasticity, memory, and cognitive flexibility. But what is Arc protein? How does it work? Inside the neuron, Arc is a protein interaction hub and dynamic regulator of intra‐cellular signaling in synaptic plasticity.

Autoinactivation of the stargazin-AMPA receptor complex: subunit-dependency and independence from physical dissociation. [PDF]
Agonist responses and channel kinetics of native α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptors are modulated by transmembrane accessory proteins.

The Impact of Glutamatergic Synapse Dysfunction in the Corticothalamocortical Network on Absence Seizure Generation [PDF]
Childhood absence epilepsy (CAE) is the most common pediatric epilepsy affecting 10–18% of all children with epilepsy. It is genetic in origin and the result of dysfunction within the corticothalamocortical (CTC) circuitry.

Absence-like seizures in the Genetic Absence Epilepsy Rats from Strasbourg (GAERS) model are believed to arise in hyperexcitable somatosensory cortical neurons, however the cellular basis of this increased excitability remains unknown. We have previously

Regulation of the Stability and Localization of Post-synaptic Membrane Proteins by Liquid-Liquid Phase Separation [PDF]
Synaptic plasticity is a cellular mechanism of learning and memory. The synaptic strength can be persistently upregulated or downregulated to update the information sent to the neuronal network and form a memory engram.
