Abstract:
The relative permeability sequences of the rat connexin 43 (rCx43) gap junction channel to seven cations and chloride were examined by double whole cell patch clamp recording of single gap junction channel currents in rCx43 transfected neuroblastoma 2A (N2A) cell pairs. The measured maximal single channel slope conductances (γj, in pS) of the junctional current-voltage relationships in 115 mM XCl were RbCl (103) ≥ CsCl (102) > KCl (97) > NaCl (79) ≥ LiCl (78) > TMACl (65) > TEACl (53) and for 115 mM KY were KBr (105) > KCl (97) > Kacetate (77) >

Abstract:
The chincona alkaloid quinine is known to be a bitter tasting substance for various vertebrates. We examined the effects of quinine on isolated taste receptor cells from the bullfrog (Rana catesbeiana). Membrane currents were recorded by whole-cell recording, while quinine hydrochloride was applied extracellularly from a puffer pipette. At the resting potential (-77 +/- 9 mV, mean +/- SD, n = 49 cells), taste cells generated inward currents in response to quinine stimulation (> 1 mM), indicating a depolarizing response in the taste cells. Two types of current responses were observed; a

Abstract:
It has been demonstrated that protamine sulfate (PS; a cationic polypeptide composed of 70% arginine) increases the apical membrane conductance of the mammalian urinary bladder. In this report, synthetic cationic polypeptides (CpP; e.g., polyarginine) were used to determine whether the response of the bladder to PS was due to its cationic nature (i.e., its arginine content). We demonstrate that CpP induce a large increase in the cation and anion conductance of the apical membrane of the rabbit urinary bladder epithelium. The modulation of the membrane conductance by CpP is dependent upon a num

It was previously demonstrated that protamine sulfate (PS, a cationic polypeptide) as well as synthetic cationic polypeptides (CpP, e.g., polylysine and polyarginine) caused an increase in the apical membrane conductance of the mammalian urinary bladder epithelium that was voltage dependent. The membrane conductance induced by these CpP was mediated by a saturable binding site and was partially blocked by CpP (self-inhibition). The PS-induced membrane conductance can be modified by polyvalent cations at three sites. The first site was to competitively inhibit the interaction of PS with an apic

Increasing extracellular pH (pHo) from 7.4 to 8.4 caused a 16-mV parallel negative shift of the activation curve for Icat evoked by guanosine 5'-O-(3-thiotriphosphate) (GTPgammaS) with an increase in the maximal conductance and slowed Icat relax

Human semen has been reported to be cytotoxic to rat descending colon by a mechanism involving polyamines (cationic molecules) and collagenase. In this study, we report that histones, cationic proteins found in human semen, can contribute to semen's cytotoxicity. Histones H1, H4, and H5, when added to the mucosal side of rabbit urinary bladder epithelium, were found to alter the transepithelial conductance (Gt) in a voltage-sensitive manner. When the cell interior was negative, the conductance rapidly increased and plateaued. When the cell interior was positive, the induced conductance decreas

In whole cell voltage-clamp studies performed at 33 degrees C, neurokinin A (NKA) and substance P (SP) reduced L-type Ca2+ current. NKA and SP activated a cationic current that reversed near 0 mV. This current (INKA or ISP, respectively) had properties similar to the acetylcholine (ACh)-activated nonselective cation conductance (IACh), activated by muscarinic stimulation in other gastrointestinal smooth muscle cells.

Abstract:
Ion channels play essential roles in the functional balance of cells, whether in the context of electrical balance or in the activation of signaling pathways for specific processes. Pore formation is a notable feature of several channels, such as P2X7R, TRPV1, TRPA1, connexins, pannexin−1, and Maxi-anion, which significantly increase the permeability of the plasma membrane, allowing high ionic conductance and molecular weights of up to 900–1000 Da.

Abstract:
Abstract AMPA-kainate receptors generally conduct monovalent cations, however, glutamate in certain neuronal cells can trigger the activation of Ca2+-permeable AMPA-kainate receptors. The different ionic selectivity depends on the combination of different subunits, and in particular on the presence of the GluR2 subunit. This subunit contains an arginine residue within the second transmembrane segment, whereas the other three subunits carry a glutamine residue at the corresponding position. This difference confers a very weak Ca2+ permeability thus determining the channel conductance and Ca2+ p
