pubmed:abstractText
A small conductance chloride channel has been identified on the apical membrane of porcine thyroid cells using the patch-clamp technique. In cell attached membrane patches with NaCl in the pipette, the single channel conductance is 5.5 pS. The channel is highly selective for chloride over gluconate and iodide, and is impermeable to Na+, K+ and tetraethylammonium ions. The open state probability of the channel is not affected by voltage. The channel activity disappears after excision of the patch. The Cl- channel blocker 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB) did not affect the activity of the thyroid Cl- channels. Treatment of thyroid cells with 8-(4-chlorophenylthio)adenosine-3',5'-cyclic monophosphate (8-chloro-cAMP) (0.5 mM) prior to giga-seal formation increased Cl- channel activity in the apical membrane of thyroid cells.
