[Mg(2+) inhibits ATP-activated current mediated by rat P2X4 receptors expressed in Xenopus oocytes].
To investigate the modulation of Mg(2+) on rat P2X4 receptors and its underlying mechanism, we transcribed cDNA coding for wild-type and mutant P2X4 receptors to cRNA in vitro, injected the cRNA to oocytes of Xenopus laevis using the microinjection technique and revealed the effect of Mg(2+) on ATP-activated currents (I(ATP)) mediated by P2X4 receptors using the two-electrode whole-cell voltage...
متن کاملATP Induced Brain-Derived Neurotrophic Factor Expression and Release from Osteoarthritis Synovial Fibroblasts Is Mediated by Purinergic Receptor P2X4
Brain-derived neurotrophic factor (BDNF), a neuromodulator involved in nociceptive hypersensitivity in the central nervous system, is also expressed in synoviocytes of osteoarthritis (OA) and rheumatoid arthritis (RA) patients. We investigated the role of P2 purinoreceptors in the induction of BDNF expression in synovial fibroblasts (SF) of OA and RA patients. Cultured SF from patients with sym...
متن کاملIonotropic purinergic receptor P2X4 is involved in the regulation of chondrogenesis in chicken micromass cell cultures.
We have previously demonstrated that elevation of free cytosolic Ca(2+) concentration at the time of differentiation of chondroblasts was mainly due to a Ca(2+) influx and it was indispensable to cartilage formation in chicken high density mesenchymal cell cultures (HDC) [C. Matta, J. Fodor, Z. Szijgyarto, T. Juhasz, P. Gergely, L. Csernoch, R. Zakany, Cytosolic free Ca(2+) concentration exhibi...
متن کاملIonic selectivity of native ATP-activated (P2X) receptor channels in dissociated neurones from rat parasympathetic ganglia.
1. The relative permeability of the native P2X receptor channel to monovalent and divalent inorganic and organic cations was determined from reversal potential measurements of ATP-evoked currents in parasympathetic neurones dissociated from rat submandibular ganglia using the dialysed whole-cell patch clamp technique. 2. The P2X receptor-channel exhibited weak selectivity among the alkali metal...
متن کاملAn electrogenic Na(+)-HCO(-)(3) cotransporter (NBC) with a novel COOH-terminus, cloned from rat brain.
We screened rat brain cDNA libraries and used 5' rapid amplification of cDNA ends to clone two electrogenic Na(+)-HCO(-)(3) cotransporter (NBC) isoforms from rat brain (rb1NBC and rb2NBC). At the amino acid level, one clone (rb1NBC) is 96% identical to human pancreas NBC. The other clone (rb2NBC) is identical to rb1NBC except for 61 unique COOH-terminal amino acids, the result of a 97-bp deleti...
