Recognition of glycine versus non‐glycine citrulline motifs dictates the HLA class II association of anti‐citrullinated protein antibodies ‐ insights from autoantibody profiling of 6900 Scandinavian rheumatoid arthritis patients

open access: yesArthritis &Rheumatology, Accepted Article.
Objectives Rheumatoid arthritis (RA) associated anti‐citrullinated protein antibodies (ACPA) target various antigens by binding short citrulline‐amino acid motifs, resulting in heterogeneous ACPA‐profiles among patients. Here we analyzed ACPA‐patterns by recognized citrulline‐motifs in relation to the RA risk factors HLA‐DRB1 shared epitope (SE ...

P2X7 receptors exert a permissive effect on the activation of presynaptic AMPA receptors in rat trigeminal caudal nucleus glutamatergic nerve terminals

open access: yesThe Journal of Headache and Pain, 2020
Background Purine receptors play roles in peripheral and central sensitization and are associated with migraine headache. We investigated the possibility that ATP plays a permissive role in the activation of AMPA receptors thus inducing Glu release from ...

AMPA, NMDA and GABAA receptor mediated network burst dynamics in cortical cultures in vitro [PDF]

open access: yesProc. Int. Works. Comp. Syst. Biol. TICSP series 8 (2011) 181-184, 2018
In this work we study the excitatory AMPA, and NMDA, and inhibitory GABAA receptor mediated dynamical changes in neuronal networks of neonatal rat cortex in vitro. Extracellular network-wide activity was recorded with 59 planar electrodes simultaneously under different pharmacological conditions.

AMPA-Net: Optimization-Inspired Attention Neural Network for Deep Compressed Sensing [PDF]

open access: yes2020 IEEE 20th International Conference on Communication Technology(Oral), 2020
Compressed sensing (CS) is a challenging problem in image processing due to reconstructing an almost complete image from a limited measurement. To achieve fast and accurate CS reconstruction, we synthesize the advantages of two well-known methods (neural network and optimization algorithm) to propose a novel optimization inspired neural network which ...

Molecular constituents of neuronal AMPA receptors [PDF]

open access: yesThe Journal of Cell Biology, 2005
Dynamic regulation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors (AMPARs) underlies aspects of synaptic plasticity. Although numerous AMPAR-interacting proteins have been identified, their quantitative and relative contributions to native AMPAR complexes remain unclear.

Role of Glutamate Excitotoxicity in Glioblastoma Growth and Its Implications in Treatment

open access: yesCell Biology International, EarlyView.
ABSTRACT Glioblastoma is a highly malignant and invasive type of primary brain tumor that originates from astrocytes. Glutamate, a neurotransmitter in the brain plays a crucial role in excitotoxic cell death. Excessive glutamate triggers a pathological process known as glutamate excitotoxicity, leading to neuronal damage.

Preferential assembly of heteromeric kainate and AMPA receptor amino terminal domains

open access: yeseLife, 2017
Ion conductivity and the gating characteristics of tetrameric glutamate receptor ion channels are determined by their subunit composition. Competitive homo- and hetero-dimerization of their amino-terminal domains (ATDs) is a key step controlling assembly.

Potential wells for AMPA receptors organized in ring nanodomains [PDF]

open access: yesarXiv, 2013
By combining high-density super-resolution imaging with a novel stochastic analysis, we report here a peculiar nano-structure organization revealed by the density function of individual AMPA receptors moving on the surface of cultured hippocampal dendrites.

A Thermodynamic Model for Receptor Clustering [PDF]

open access: yes, 1999
Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.
