  • Title: Voltage-dependent ion channels in the mouse RPE: comparison with Norrie disease mice.
    Author: Wollmann G, Lenzner S, Berger W, Rosenthal R, Karl MO, Strauss O.
    Journal: Vision Res; 2006 Mar; 46(5):688-98. PubMed ID: 16289664.
    Abstract:
    We studied electrophysiological properties of cultured retinal pigment epithelial (RPE) cells from mouse and a mouse model for Norrie disease. Wild-type RPE cells revealed the expression of ion channels known from other species: delayed-rectifier K(+) channels composed of Kv1.3 subunits, inward rectifier K(+) channels, Ca(V)1.3 L-type Ca(2+) channels and outwardly rectifying Cl(-) channels. Expression pattern and the ion channel characteristics current density, blocker sensitivity, kinetics and voltage-dependence were compared in cells from wild-type and Norrie mice. Although no significant differences were observed, our study provides a base for future studies on ion channel function and dysfunction in transgenic mouse models.
