Potentiation and inhibition of glycine receptors by tutin [PDF]

Neuropharmacology, 2011
In the present study we characterized the effects of the South American neurotoxin tutin on recombinant glycine receptors (GlyR) expressed in HEK 293 cells using whole-cell patch-clamp techniques. Tutin induced a concentration-dependent inhibition of α(1) and α(2) homomeric GlyRs, with IC(50)s of 35 ± 1 and 15 ± 3 μM, respectively. The co-expression of

Bacteria‐Derived Extracellular Vesicle as A “Trojan Horse” for Selective M1 Macrophage‐Targeting in A Multi‐Cellular Entanglement Environment

Advanced Functional Materials, EarlyView.
The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Potentiation of Glycine-Gated NR1/NR3A NMDA Receptors Relieves Ca2+-Dependent Outward Rectification [PDF]

, 2010
Glycine has diverse functions within the mammalian central nervous system. It inhibits postsynaptic neurons via strychnine-sensitive glycine receptors (GlyRs) and enhances neuronal excitation through co-activation of N-methyl-D-aspartate (NMDA) receptors.

Glutamate and Glycine Binding to the NMDA Receptor [PDF]

Structure, 2018
At central nervous system synapses, agonist binding to postsynaptic ionotropic glutamate receptors (iGluRs) results in signaling between neurons. N-Methyl-D-aspartic acid (NMDA) receptors are a unique family of iGluRs that activate in response to the concurrent binding of glutamate and glycine. Here, we investigate the process of agonist binding to the

Stable, Easy‐to‐Handle, Fully Autologous Electrospun Polymer‐Peptide Skin Equivalent for Severe Burn Injuries

Advanced Functional Materials, EarlyView.
A bioengineered skin equivalent composed of electrospun poly(ε‐caprolactone) (PCL) and the bioactive peptide Fmoc‐FRGD is developed for severe burn treatment. This scaffold promotes full‐thickness skin regeneration by supporting cellular adhesion and integration. In‐vitro and in‐vivo studies show enhanced mechanical stability, accelerated wound closure,

The activation mechanism of alpha 1 homomeric glycine receptors [PDF]

, 2004
The glycine receptor mediates fast synaptic inhibition in the spinal cord and brainstem. Its activation mechanism is not known, despite the physiological importance of this receptor and the fact that it can serve as a prototype for other homopentameric ...

Identification of amino acid residues of the NR2A subunit that control glutamate potency in recombinant NR1/NR2A NMDA receptors [PDF]

, 1998
The NMDA type of ligand-gated glutamate receptor requires the presence of both glutamate and glycine for gating. These receptors are hetero-oligomers of NR1 and NR2 subunits. Previously it was thought that the binding sites for glycine and glutamate were

Mechanism of glycine protection in hypoxic injury: Analogies with glycine receptor [PDF]

Kidney International, 1992
Addition of glycine to the recirculating perfusate of isolated perfused rat kidneys protects against hypoxic injury to the medullary thick ascending limb and slows functional deterioration in the course of perfusion. This effect is dependent on dose; the earliest significant protection is seen at 0.25 mM, and the protective effects increase as glycine ...

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

Advanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence

Openings of the rat recombinant alpha1 homomeric glycine receptor as a function of the number of sgonist molecules bound [PDF]

, 2002
The functional properties of rat homomeric {alpha}1 glycine receptors were investigated using whole-cell and outside-out recording from human embryonic kidney cells transfected with rat {alpha}1 subunit cDNA.
