Since the lateral diffusion of membrane receptors is an important indicator of their function, a deeper understanding of the underlying mechanisms of non-classical estradiol actions can be achieved by investigating receptor dynamics. Diffusion coefficient is a crucial and widely used parameter to characterize the movement of receptors in the cell membrane. The aim of this study was to investigate the differences between maximum likelihood-based estimation (MLE) and mean square displacement (MSD) based calculation of diffusion coefficients. In this work we applied both MSD and MLE to calculate diffusion coefficients. Single particle trajectories were extracted from simulation as well as from α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor tracking in live estradiol-treated differentiated PC12 (dPC12) cells. The comparison of the obtained diffusion coefficients revealed the superiority of MLE over the generally used MSD analysis. Our results suggest the use of the MLE of diffusion coefficients because as it has a better performance, especially for large localization errors or slow receptor movements.}, year = {2023}, eissn = {1662-5196} } @article{MTMT:32235080, title = {Single-Molecule Imaging Reveals Rapid Estradiol Action on the Surface Movement of AMPA Receptors in Live Neurons}, url = {https://m2.mtmt.hu/api/publication/32235080}, author = {Godó, Soma and Barabás, Klaudia and Lengyel, Ferenc and Ernszt, Dávid and Kovács, Tamás and Kecskés, Miklós and Varga, Csaba and Jánosi, Tibor Zoltán and Makkai, Géza and Kovács, Gergely and Orsolits, Barbara and Fujiwara, Takahiro and Kusumi, Akihiro and Ábrahám, István}, doi = {10.3389/fcell.2021.708715}, journal-iso = {FRONT CELL DEV BIOL}, journal = {FRONTIERS IN CELL AND DEVELOPMENTAL BIOLOGY}, volume = {9}, unique-id = {32235080}, issn = {2296-634X}, abstract = {Gonadal steroid 17β-estradiol (E2) exerts rapid, non-genomic effects on neurons and strictly regulates learning and memory through altering glutamatergic neurotransmission and synaptic plasticity. However, its non-genomic effects on AMPARs are not well understood. Here, we analyzed the rapid effect of E2 on AMPARs using single-molecule tracking and super-resolution imaging techniques. We found that E2 rapidly decreased the surface movement of AMPAR via membrane G protein-coupled estrogen receptor 1 (GPER1) in neurites in a dose-dependent manner. The cortical actin network played a pivotal role in the GPER1 mediated effects of E2 on the surface mobility of AMPAR. E2 also decreased the surface movement of AMPAR both in synaptic and extrasynaptic regions on neurites and increased the synaptic dwell time of AMPARs.

Resolvins are endogenous lipid mediators. Resolvin D1 (RvD1) is described as a selective inhibitor of TRPA1-related postoperative and inflammatory pain in mice acting on the G protein-coupled receptor DRV1/GPR32. Resolvin D2 (RvD2) is a very potent TRPV1 and TRPA1 inhibitor in DRG neurons, and decreases inflammatory pain in mice acting on the GPR18 receptor, via TRPV1/TRPA1-independent mechanisms. We provided evidence that resolvins inhibited neuropeptide release from the stimulated sensory nerve terminals by TRPV1 and TRPA1 activators capsaicin (CAPS) and allyl-isothiocyanate (AITC), respectively. We showed that RvD1 and RvD2 in nanomolar concentrations significantly decreased TRPV1 and TRPA1 activation on sensory neurons by fluorescent calcium imaging and inhibited the CAPS-and AITC-evoked45Ca-uptake on TRPV1-and TRPA1-expressing CHO cells. Since CHO cells are unlikely to express resolvin receptors, resolvins are suggested to inhibit channel opening through surrounding lipid raft disruption. Here, we proved the ability of resolvins to alter the membrane polarity related to cholesterol composition by fluorescence spectroscopy. It is concluded that targeting lipid raft integrity can open novel peripheral analgesic opportunities by decreasing the activation of nociceptors. © 2020 by the authors.

Therefore, our aim was to investigate whether this compound exerts its effect through lipid raft disruption and the steroid backbone (C3) or altered position of the carboxamido group (C2) influence the inhibitory action by measuring Ca2+-transients on isolated neurons and calcium-uptake on receptor-expressing CHO cells. Membrane cholesterol content was measured by filipin staining and membrane polarisation by fluorescence spectroscopy. Both the percentage of responsive cells and the magnitude of the intracellular Ca2+-enhancement evoked by the TRPV1 agonist capsaicin were significantly inhibited after C1 and C2 incubation, but not after C3 administration. C1 was able to reduce other TRP channel activation as well. The compounds induced cholesterol depletion in CHO cells, but only C1 induced changes in membrane polarisation. The inhibitory action of the compounds on TRP channel activation develops by lipid raft disruption, and the presence and the position of the carboxamido group is essential.}, keywords = {CELL-LINE; ACTIVATION; NICOTINIC ACETYLCHOLINE-RECEPTOR; ROOT GANGLION NEURONS; LIPID RAFTS; steroid; transient receptor potential channel; TRPV1 receptor; sensory neuron; Cation channels; nerve terminal; TRIGEMINAL SENSORY NEURONS; ALPHA-SPINASTEROL; SCREEN REVEALS}, year = {2018}, eissn = {1539-7262}, pages = {1851-1863}, orcid-numbers = {Sághy, Éva/0000-0002-4031-3461; Skodáné Földes, Rita/0000-0002-9810-1509; Szánti-Pintér, Eszter/0000-0001-8263-9884} } @article{MTMT:3000846, title = {Light-Enhanced Fluorescence of Multi-Level Cavitands Possessing Pyridazine Upper rim}, url = {https://m2.mtmt.hu/api/publication/3000846}, author = {Jánosi, Tibor Zoltán and Makkai, Géza and Kégl, Tímea and Mátyus, Péter and Kollár, László and Erostyák, János}, doi = {10.1007/s10895-015-1754-3}, journal-iso = {J FLUORESC}, journal = {JOURNAL OF FLUORESCENCE}, volume = {26}, unique-id = {3000846}, issn = {1053-0509}, year = {2016}, eissn = {1573-4994}, pages = {679-688}, orcid-numbers = {Mátyus, Péter/0000-0003-3963-9445} }
