Method for identification of condition-associated public antigen receptor sequences [PDF]

open access: yeseLife 2018;7:e33050, 2017
Diverse repertoires of hypervariable immunoglobulin receptors (TCR and BCR) recognize antigens in the adaptive immune system. The development of immunoglobulin receptor repertoire sequencing methods makes it possible to perform repertoire-wide disease association studies of antigen receptor sequences.

Assembly and Stoichiometry of the AMPA Receptor and Transmembrane AMPA Receptor Regulatory Protein Complex [PDF]

open access: yesThe Journal of Neuroscience, 2010
Glutamate is a major excitatory neurotransmitter in the vertebrate brain. AMPA-type glutamate receptors mediate fast excitatory transmission. AMPA receptors assemble with transmembrane AMPA receptor regulatory protein (TARP) auxiliary subunits and function as native ion channels.

Desensitization dynamics of the AMPA receptor

open access: yesStructure, 2023
To perform their physiological functions, amino methyl propionic acid receptors (AMPARs) cycle through active, resting, and desensitized states, and dysfunction in AMPAR activity is associated with various neurological disorders. Transitions among AMPAR functional states, however, are largely uncharacterized at atomic resolution and are difficult to ...

Regulation of PVT‐CeA Circuit in Deoxynivalenol‐Induced Anorexia and Aversive‐Like Emotions

open access: yesAdvanced Science, EarlyView.
The study investigates Deoxynivalenol (DON) effects on feeding and emotions, focusing on the central amygdala (CeA). Acute DON exposure reduces food intake and alters behavior, linked to CeAGABA neuron activity and PVT‐CeA connectivity. Manipulating CeAGABA neurons and using SCN10A antagonist A‐803467 alleviate DON's effects, offering potential ...

Regulation of Neuromodulator Receptor Efficacy - Implications for Whole-Neuron and Synaptic Plasticity [PDF]

open access: yesProgress in Neurobiology 72(6), pp 399-415, April 2004, 2004
Membrane receptors for neuromodulators (NM) are highly regulated in their distribution and efficacy - a phenomenon which influences the individual cell's response to central signals of NM release. Even though NM receptor regulation is implicated in the pharmacological action of many drugs, and is also known to be influenced by various environmental ...

Analog Implementation of a Spiking System for Performing Arithmetic Logic Operations on Mixed‐Signal Neuromorphic Processors

open access: yesAdvanced Intelligent Systems, EarlyView.
This article describes the spiking implementation of an arithmetic logic unit, the fundamental basis of which lies in the use of spiking logic gates. An extensive series of experiments validates the implemented designs on SpiNNaker and Dynap‐SE. This work takes a first step in the implementation of a spiking central processing unit.

Stargazin Dephosphorylation Mediates Homeostatic Synaptic Downscaling of Excitatory Synapses

open access: yesFrontiers in Molecular Neuroscience, 2018
Synaptic scaling is a form of homeostatic plasticity that is critical for maintaining neuronal activity within a dynamic range, and which alters synaptic strength through changes in postsynaptic AMPA-type glutamate receptors.

Acute inactivation of PSD-95 destabilizes AMPA receptors at hippocampal synapses. [PDF]

open access: yesPLoS ONE, 2013
Postsynatptic density protein (PSD-95) is a 95 kDa scaffolding protein that assembles signaling complexes at synapses. Over-expression of PSD-95 in primary hippocampal neurons selectively increases synaptic localization of AMPA receptors; however, mice ...

Dysregulation of AMPA Receptor Trafficking and Intracellular Vesicular Sorting in the Prefrontal Cortex of Dopamine Transporter Knock-Out Rats

open access: yesBiomolecules, 2023
Dopamine (DA) and glutamate interact, influencing neural excitability and promoting synaptic plasticity. However, little is known regarding the molecular mechanisms underlying this crosstalk.

Super-Resolution Imaging Reveals That AMPA Receptors Inside Synapses Are Dynamically Organized in Nanodomains Regulated by PSD95

open access: yesJournal of Neuroscience, 2013
The spatiotemporal organization of neurotransmitter receptors in postsynaptic membranes is a fundamental determinant of synaptic transmission and information processing by the brain. Using four independent super-resolution light imaging methods and EM of
