The tallest is called Asinelli, the smallest and more leaning tower is called Garisenda, from the names of the families that wanted their construction at the beginning of the XII century (1109-1119). Mentioned by Dante in the Divine Comedy, by Goethe in the Italian Journey, and by other poets and writers in the following centuries, the Two Towers are the landmark of Bologna and located in center town, at the intersection of the most ancient streets (including via Zamboni, the main artery of the University district). The Alma Mater Studiorum University of Bologna had been founded some years before, in 1088. The photo has been taken by Prof. Jaroslav Pokorný, President of the Czech Physiological Society from a terrace at the beginning of via Zamboni during his stay in Bologna for the Meeting of the International Scientifi c Committee in preparation of the FEPS-SIF 2019 Congress.

  • TRP Channel Transient Receptor Potential Channels
    TRP Channel Transient receptor potential channels TRP Channel (Transient receptor potential channel) is a group of ion channels located mostly on the plasma membrane of numerous human and animal cell types. There are about 28 TRP channels that share some structural similarity to each other. These are grouped into two broad groups: Group 1 includes TRPC ("C" for canonical), TRPV ("V" for vanilloid), TRPM ("M" for melastatin), TRPN, and TRPA. In group 2, there are TRPP ("P" for polycystic) and TRPML ("ML" for mucolipin). Many of these channels mediate a variety of sensations like the sensations of pain, hotness, warmth or coldness, different kinds of tastes, pressure, and vision. TRP channels are relatively non-selectively permeable to cations, including sodium, calcium and magnesium. TRP channels are initially discovered in trp-mutant strain of the fruit fly Drosophila. Later, TRP channels are found in vertebrates where they are ubiquitously expressed in many cell types and tissues. TRP channels are important for human health as mutations in at least four TRP channels underlie disease. www.MedChemExpress.com 1 TRP Channel Inhibitors, Antagonists, Agonists, Activators & Modulators (-)-Menthol (E)-Cardamonin Cat.

There are no effective disease-preventing therapies for these pathologies. Recent in vitro and in vivo studies have revealed the TRPC6 channel to be a promising molecular target for the development of neuroprotective agents. TRPC6 channel is a non-selective cation plasma membrane channel that is permeable to Ca2+. Its Ca2+-dependent pharmacological effect is associated with the stabilization and protection of excitatory synapses. Downregulation as well as upregulation of TRPC6 channel functions have been observed in Alzheimer’s disease and brain ischemia models.

  • Direct Activation of TRPC3 Channels by the Antimalarial Agent Artemisinin
    cells Article Direct Activation of TRPC3 Channels by the Antimalarial Agent Artemisinin Nicole Urban and Michael Schaefer * Leipzig University, Medical Faculty, Rudolf Boehm Institute of Pharmacology and Toxicology, Härtelstraße 16-18, 04107 Leipzig, Germany; [email protected] * Correspondence: [email protected]; Tel.: +49-341-97-24600 Received: 29 November 2019; Accepted: 9 January 2020; Published: 14 January 2020 Abstract: (1) Background: Members of the TRPC3/TRPC6/TRPC7 subfamily of canonical transient receptor potential (TRP) channels share an amino acid similarity of more than 80% and can form heteromeric channel complexes. They are directly gated by diacylglycerols in a protein kinase C-independent manner. To assess TRPC3 channel functions without concomitant protein kinase C activation, direct activators are highly desirable. (2) Methods: By screening 2000 bioactive compounds in a Ca2+ influx assay, we identified artemisinin as a TRPC3 activator. Validation and characterization of the hit was performed by applying fluorometric Ca2+ influx assays and electrophysiological patch-clamp experiments in heterologously or endogenously TRPC3-expressing cells. (3) Results: Artemisinin elicited Ca2+ entry through TRPC3 or heteromeric TRPC3:TRPC6 channels, but did not or only weakly activated TRPC6 and TRPC7. Electrophysiological recordings confirmed the reversible and repeatable TRPC3 activation by artemisinin that was inhibited by established TRPC3 channel blockers. Rectification properties and reversal potentials were similar to those observed after stimulation with a diacylglycerol mimic, indicating that artemisinin induces a similar active state as the physiological activator. In rat pheochromocytoma PC12 cells that endogenously express TRPC3, artemisinin induced a Ca2+ influx and TRPC3-like currents. (4) Conclusions: Our findings identify artemisinin as a new biologically active entity to activate recombinant or native TRPC3-bearing channel complexes in a membrane-confined fashion.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Chronic pathological pain is one of the most intractable clinical problems faced by clinicians and can be devastating for patients. Despite much progress we have made in understanding chronic pain in the last decades, its underlying mechanisms remain elusive. It is assumed that abnormal increase of calcium levels in the cells is a key determinant in the transition from acute to chronic pain. Exploring molecular players mediating Ca2+ entry into cells and molecular mechanisms underlying activity- dependent changes in Ca2+ signaling in the somatosensory pain pathway is therefore helpful towards understanding the development of chronic, pathological pain. Canonical transient receptor potential (TRPC) channels form a subfamily of nonselective cation channels, which permit the permeability of Ca2+ and Na+ into the cells.

  • Stretch-Activated Channels in Heart Valve Cells
    Stretch-Activated Channels in Heart Valve Cells A thesis submitted to Imperial College London for the degree of Doctor of Philosophy Hessah F. Alshammari January 2019 National Heart and Lung Institute Faculty of Medicine Imperial College London Abstract The aortic valve is a sophisticated structure that performs complex functions to preserve the unidirectional flow of blood and maintenance of myocardial function. Valve endothelial cells (VECs) cover the two surfaces of aortic valve cusps in a continuous layer consisting of the endocardium and the sinus wall endothelium. Valve interstitial cells (VICs) are a heterogeneous and dynamic population of cells that form the body of valve cusps and are located within the extracellular matrix. VECs experience continuous and different mechanical forces in both side and VICs are experience continuous and varying mechanical forces, including stretch. These mechanical forces are translated to the cells via electrochemical or biochemical signals through mechanotransduction pathways, which may include stretch-activated ion channels (SACs) which are membrane proteins capable of responding to mechanical force and activate intracellular signalling pathways that mediate the functional response of the cells. The overall aim of this study was to investigate SACs presence and their functional roles in VECs and VICs. The presence of stretch-activated ion channels was studied electrophysiologically and biochemically in VECs from each side of the valve and different phenotypes of VICs. The role of SAC on alignment of and proliferation VECs, migration and collagen production in VICs were assessed. Stretch-activated ion channels receptors including (KCNK2, KCNJ8, TRPM4, TRPV4 and TRPC6) were present in VECs and VICs.

However, little is known about its mechanism in improving proteinuria. The dysregulation of podocyte cell-matrix adhesion has been demonstrated to play an important role in the pathogenesis and progression of proteinuric kidney diseases including DKD.
