The copper-dependence of O-2 transport, metabolism and production of signalling molecules are supported by molecular systems that regulate and preserve tightly-bound static and weakly-bound dynamic cellular copper pools. Disruption of the reducing intracellular environment, characterized by glutathione shortage and ambient Cu(II) abundance drives oxidative stress and interferes with the bidirectional, copper-dependent communication between neurons and astrocytes, eventually leading to various brain disease forms. A deeper understanding of of the regulatory effects of copper on neuro-glia coupling via polyamine metabolism may reveal novel copper signalling functions and new directions for therapeutic intervention in brain disorders associated with aberrant copper metabolism.}, keywords = {GSH; Redox disproportionation and speciation of copper; Dynamic copper pool; Copper-rich aggregates; GSSG ratio; Copper chelate therapy; Neuro-glia coupling}, year = {2018}, eissn = {1478-811X} } @article{MTMT:3149898, title = {Kinetics of the reversible inclusion of flavopereirine in cucurbit[7]uril}, url = {https://m2.mtmt.hu/api/publication/3149898}, author = {Miskolczy, Zsombor and Biczók, László and Jablonkai, István}, doi = {10.1039/c6cp07553c}, journal-iso = {PHYS CHEM CHEM PHYS}, journal = {PHYSICAL CHEMISTRY CHEMICAL PHYSICS}, volume = {19}, unique-id = {3149898}, issn = {1463-9076}, year = {2017}, eissn = {1463-9084}, pages = {766-773}, orcid-numbers = {Biczók, László/0000-0003-2568-5942} } @article{MTMT:3148042, title = {A transgenic rat hepatocyte - Kupffer cell co-culture model for evaluation of direct and macrophage-related effect of poly(amidoamine) dendrimers}, url = {https://m2.mtmt.hu/api/publication/3148042}, author = {Jemnitz, Katalin and Batai-Konczos, A and Szabó, Mónika and Ioja, Enikő and Kolacsek, Orsolya and Orbán, Tamás I. and Török, György and Homolya, László and Kovacs, E and Jablonkai, István and Veres, Zsuzsa}, doi = {10.1016/j.tiv.2016.09.016}, journal-iso = {TOXICOL IN VITRO}, journal = {TOXICOLOGY IN VITRO}, volume = {38}, unique-id = {3148042}, issn = {0887-2333}, abstract = {Increasing number of papers demonstrate that Kupffer cells (KCs) play a role in the development of drug induced liver injury (DILI). Furthermore, elevated intracellular Ca2+ level of hepatocytes is considered as a common marker of DILI. Here we applied an in vitro model based on hepatocyte mono- and hepatocyte/KC co-cultures (H/KC) isolated from transgenic rats stably expressing the GCaMP2 fluorescent Ca2+ sensor protein to investigate the effects of polycationic (G5), polyanionic (G4.5) and polyethylene-glycol coated neutral (G5 Peg) dendrimers known to accumulate in the liver, primarily in KCs. Following dendrimer exposure, hepatocyte homeostasis was measured by MTT cytotoxicity assay and by Ca2+ imaging, while hepatocyte functions were studied by CYP2B1/2 inducibility, and bilirubin and taurocholate transport. G5 was significantly more cytotoxic than G4.5 for hepatocytes and induced Ca2+ oscillation and sustained Ca2+ signals at 1muM and10 muM, respectively both in hepatocytes and KCs. Dendrimer-induced Ca2+ signals in hepatocytes were attenuated by macrophages. Activation of KCs by lipopolysaccharide and G5 decreased the inducibility of CYP2B1/2, which was restored by depleting the KCs with gadolinium-chloride and pentoxyphylline, suggesting a role of macrophages in the hindrance of CYP2B1/2 induction by G5 and lipopolysaccharide. In the H/KC, but not in the hepatocyte mono-culture, G5 reduced the canalicular efflux of bilirubin and stimulated the uptake and canalicular efflux of taurocholate. In conclusion, H/KC provides a good model for the prediction of hepatotoxic potential of drugs, especially of nanomaterials known to be trapped by macrophages, activation of which presumably contributes to DILI.}, year = {2017}, eissn = {1879-3177}, pages = {159-169}, orcid-numbers = {Orbán, Tamás I./0000-0002-3424-3428; Török, György/0000-0001-7616-5782; Homolya, László/0000-0003-1639-8140} } @article{MTMT:3068584, title = {Multiple inclusion complex formation of protonated ellipticine with cucurbit[8]uril: thermodynamics and fluorescence properties}, url = {https://m2.mtmt.hu/api/publication/3068584}, author = {Miskolczy, Zsombor and Biczók, László and Jablonkai, István}, doi = {10.1080/10610278.2016.1174237}, journal-iso = {SUPRAMOL CHEM}, journal = {SUPRAMOLECULAR CHEMISTRY}, volume = {28}, unique-id = {3068584}, issn = {1061-0278}, abstract = {The encapsulation of protonated ellipticine (EH+) in the cavity of cucurbit[8]uril (CB8) was studied in water at pH 4 with spectrophotometric, fluorescence spectroscopic and isothermal calorimetric measurements.

Not only one, but also two EH+ was capable of encapsulation in CB8 in 37 μM EH+ solution and the thermodynamics of the binding steps were revealed. The produced very stable complexes showed markedly different absorption and fluorescence properties. When large excess of CB8 was employed in dilute (0.49 μM) EH+ solution, sequential binding of two CB8 occurred to the monomer alkaloid bringing about a substantial alteration in the fluorescence decay kinetics.
