Therefore, sst4 agonists are promising novel drug candidates for neuropathic pain and neurogenic inflammation, but rational drug design was not possible due to the lack of knowledge about its 3-dimensional structure. We modeled the sst4 receptor structure, described its agonist binding properties, and characterized the binding of our novel small molecule sst4 agonists (4-phenetylamino-7H-pyrrolo[2,3-d]pyrimidine derivatives) using an in silico platform. In addition to the in silico binding data, somatostatin displacement by Compound 1 was demonstrated in the competitive binding assay on sst4-expressing cells. In vivo effects were investigated in rat models of neurogenic inflammation and chronic traumatic neuropathic pain. We defined high- and low-affinity binding pockets of sst4 for our ligands, binding of the highest affinity compounds were similar to that of the reference ligand J-2156. We showed potent G-protein activation with the highest potency of 10 nM EC50 value and highest efficacy of 342%. Oral administration of 100 μg/kg of 5 compounds significantly inhibited acute neurogenic plasma protein extravasation in the paw skin by 40-60%, one candidate abolished and 3 others diminished sciatic nerve-ligation induced neuropathic hyperalgesia by 28-62%. The in silico predictions on sst4-ligands were tested in biological systems. Low oral dose of our novel agonists inhibit neurogenic inflammation and neuropathic pain, which opens promising drug developmental perspectives for these unmet medical need conditions.}, keywords = {Inflammation; SOMATOSTATIN; Neuropathic pain; somatostatin receptor subtype 4; Analgesic drug; Anti-inflammatory drug}, year = {2020}, eissn = {1873-7064}, orcid-numbers = {Őrfi, László/0000-0001-6149-2385; Pintér, Erika/0000-0001-9898-632X} } @article{MTMT:31387590, title = {Resolvin D1 and D2 inhibit transient receptor potential vanilloid 1 and ankyrin 1 ion channel activation on sensory neurons via lipid raft modification}, url = {https://m2.mtmt.hu/api/publication/31387590}, author = {Payrits, Maja and Horváth, Ádám and Biró-Sütő, Tünde and Erostyák, János and Makkai, Géza and Sághy, Éva and Pohóczky, Krisztina and Kecskés, Angéla and Kecskés, Miklós and Szolcsányi, János and Helyes, Zsuzsanna and Szőke, Éva}, doi = {10.3390/ijms21145019}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {21}, unique-id = {31387590}, issn = {1661-6596}, abstract = {Transient Receptor Potential Vanilloid 1 and Ankyrin 1 (TRPV1, TRPA1) cation channels are expressed in nociceptive primary sensory neurons and regulate nociceptor and inflammatory functions. 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.

This study aimed to determine their role in the collagen-antibody induced rheumatoid arthritis model. Capsaicin-sensitive nerves were defunctionalized by the capsaicin receptor agonist resiniferatoxin in C57Bl/6 mice. Arthritis was induced by the ArithroMab antibody cocktail and adjuvant. Arthritis was monitored by measuring body weight, joint edema by plethysmometry, arthritis severity by clinical scoring, mechanonociceptive threshold by plantar esthesiometry, thermonociceptive threshold by hot plate, cold tolerance by paw withdrawal latency from 0 °C water. Grasping ability was determined by the wire-grid grip test. Bone structure was evaluated by in vivo micro-CT and histology. Arthritic animals developed a modest joint edema, mechanical and cold hyperalgesia, weight loss, and a diminished grasping function, while thermal hyperalgesia is absent in the model. Desensitised mice displayed reduced arthritis severity, edema, and mechanical hyperalgesia, however, cold hyperalgesia was significantly greater in this group. Arthritic controls displayed a transient decrease of bone volume and an increased porosity, while bone density and trabecularity increased in desensitised mice. The activation of capsaicin-sensitive afferents increases joint inflammation and mechanical hyperalgesia, but decreases cold allodynia.

We provided evidence that lipid raft disruption influenced the TRP channel activation and a carboxamido-steroid compound (C1) inhibited TRPV1 activation. 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.

Neuronal Transient Receptor Potential Vanilloid 1 (TRPV1) and Ankyrin 1 (TRPA1) channels have been implicated in the pathogenesis of CRS. We aimed to detect the expression of extraneuronal TRPV1 and TRPA1 receptors in nasal polyp (NP) tissue samples. METHODOLOGY: Samples were obtained from fourty-two CRS pateints with nasal polyp and sixteen healthy controls to measure receptor gene expression by quantitative PCR, protein localization by immunohistochemistry and cytokine profile by multiplex bead immunoassay. RESULTS: Non-neuronal TRPV1, TRPA1 receptors were expressed in biopsy samples of NP. A population of mast cells and macrophages were immunopositive for TRPV1 and TRPA1. A fraction of plasma cells expressed TRPV1 but not TRPA1 and neither receptor was present on eosinophils. The local gene expression of extraneuronal TRPV1, TRPA1 receptors was also proven. TRPV1 mRNA levels were significantly increased in CRSwNP patients with asthma and allergic rhinitis compared to their NP counterparts. CONCLUSIONS: Elevated TRPV1 levels in comorbid asthma and allergy may have a function in CRSwNP. Subpopulation-specific TRPV1 presence on plasma and mast cells can indicate delicate roles in regulating activation and release of inflammatory mediators.}, year = {2018}, eissn = {0300-0729}, pages = {245-254}, orcid-numbers = {Piski, Zalán/0000-0003-2592-9652; Kemény, Ágnes/0000-0002-4523-3938; Pintér, Erika/0000-0001-9898-632X} } @article{MTMT:3297015, title = {Nils Alwall a művese egyik alaptípusának feltalálója és magyar kapcsolata}, url = {https://m2.mtmt.hu/api/publication/3297015}, author = {Karátson, András and Szolcsányi, János}, journal-iso = {HYPERTONIA NEPHROLOGIA}, journal = {HYPERTONIA ÉS NEPHROLOGIA}, volume = {21}, unique-id = {3297015}, issn = {1418-477X}, year = {2017}, eissn = {2498-6259}, pages = {44-48} } @article{MTMT:3248672, title = {Estradiol sensitizes the Transient Receptor Potential Vanilloid 1 receptor in pain responses}, url = {https://m2.mtmt.hu/api/publication/3248672}, author = {Payrits, Maja and Sághy, Éva and Csekő, Kata and Pohóczky, Krisztina and Bölcskei, Kata and Ernszt, Dávid and Barabás, Klaudia and Szolcsányi, János and Ábrahám, István and Helyes, Zsuzsanna and Szőke, Éva}, doi = {10.1210/en.2017-00101}, journal-iso = {ENDOCRINOLOGY}, journal = {ENDOCRINOLOGY}, volume = {158}, unique-id = {3248672}, issn = {0013-7227}, year = {2017}, eissn = {1945-7170}, pages = {3249-3258}, orcid-numbers = {Sághy, Éva/0000-0002-4031-3461; Pohóczky, Krisztina/0000-0003-0385-5162} }
