Cys-loop receptors (CLR) are pentameric ligand-gated ion channels that mediate fast excitatory or inhibitory transmission in the nervous system. Strychnine and d-tubocurarine (d-TC) are neurotoxins that have been highly instrumental in decades of research on glycine receptors (GlyR) and nicotinic acetylcholine receptors (nAChR), respectively. In this study(More)
The Cys-loop receptor family consists of nicotinic acetylcholine receptors (nAChR), glycine receptor, GABA-A and some other receptors. They fulfill a plethora of functions, whereas their malfunctioning is associated with many diseases. All three domains - extracellular ligand-binding, membrane and cytoplasmic - of these ligand-gated ion channels play(More)
Cys-loop receptors are pentameric ligand-gated ion channels (pLGICs) that mediate fast synaptic transmission. Here functional pentameric assembly of truncated fragments comprising the ligand-binding N-terminal ectodomains and the first three transmembrane helices, M1-M3, of both the inhibitory glycine receptor (GlyR) alpha1 and the 5HT(3)A receptor subunits(More)
Transverse-electric (TE) surface plasmons (SPs) are very unusual for plasmonics phenomenon. Graphene proposes a unique possibility to observe these plasmons. Due to transverse motion of carriers, TE SPs speed is usually close to bulk light one. In this work we discuss conditions of TE SPs propagation in cylindrical graphene-based waveguides. We found that(More)
Siberian stone pine, Pinus sibirica Du Tour is one of the most economically and environmentally important forest-forming species of conifers in Russia. To study these forests a large number of highly polymorphic molecular genetic markers, such as microsatellite loci, are required. Prior to the new high-throughput next generation sequencing (NGS) methods,(More)
The divalent cation copper (Cu2+) has been shown to inhibit chloride currents mediated by the inhibitory glycine receptor (GlyR). Here, we analyzed Cu2+ inhibition of homo- and hetero-oligomeric GlyRs expressed in Xenopus oocytes. No significant differences in Cu2+ inhibitory potency were found between alpha1, alpha2 and alpha3 GlyRs as well as heteromeric(More)
Weak toxins are the "three-fingered" snake venoms toxins grouped together by having an additional disulfide in the N-terminal loop I. In general, weak toxins have low toxicity, and biological targets have been identified for some of them only, recently by detecting the effects on the nicotinic acetylcholine receptors (nAChR). Here the methods of docking and(More)
