Previous studies using the patch-clamp technique demonstrated the presence of a small conductance Cl(-) channel in the apical membrane of respiratory gill cells in primary culture originating from sea bass Dicentrarchus labrax. We used the same technique here to characterize potassium channels in this model. A K(+) channel of 123 +/- 3 pS was...
Previous studies performed on apical membranes of seawater fish gills in primary culture have demonstrated the existence of stretch-activated K(+) channels with a conductance of 122 pS. The present report examines the involvement of K(+) channels in ion transport mechanisms and cell swelling. In the whole cell patch-clamp configuration, K(+)...

The clinical use of the antineoplastic drug cisplatin is limited by its deleterious nephrotoxic side effect. Cisplatin-induced nephrotoxicity is associated with an increase in oxidative stress, leading ultimately to renal cell death and irreversible kidney dysfunction. Oxidative stress could be modified by the cystic fibrosis transmembrane...
We have previously shown that K(+)-selective TASK2 channels and swelling-activated Cl(-) currents are involved in a regulatory volume decrease (RVD; Barriere H, Belfodil R, Rubera I, Tauc M, Lesage F, Poujeol C, Guy N, Barhanin J, Poujeol P.

Alveolar echinococcosis (AE) is a helminth zoonosis which is encountered only in the northern hemisphere. In central France, the Auvergne region represents the most western and southern extension of this helminthiasis. In 1999, a human case of AE was diagnosed in the southern part of the Cantal department, where AE was supposed absent, and an...
IntroductionLes patients atteints de maladie rénale chronique(MRC) développent des calcifications de la media artérielle favorisées par la sursaturation phospho-calcique. Les patients atteints de Pseudoxanthome Elastique(PXE), une maladie génétique secondaire à des mutations du gène ABCC6 développent des calcifications artérielles similaires....
