Not Volatile Anesthetics Addressing the Two-Pore Domain K+ Channel, TASK-1, Slows Down Cilia-Driven Particle Transport in the Mouse Trachea.
BACKGROUND volatile anesthetics inhibit mucociliary clearance in the airways. Two-pore domain K + channels, TASK-1, is one of their molecular targets that they increase the probability of open. Here, we determine whether the speed of transport of particles (PTS) in the mucosal Mouse Clia Kits surface of the mouse trachea, is an important factor of cilia-driven mechanism of mucociliary clearance, is governed by the TASK-1. RESULTS RT-PCR analysis revealed expression of TASK-1 mRNA in the dissected and laser-assisted tracheal epithelium microdissected mouse. Anesthesia (isoflurane and Avertin®) and TASK-1 inhibitor (anandamide and A293) cilia activity was investigated by the assessment of PTS in murine tracheal mucosal surface of explanted and opened. Both TASK-1 inhibitor or isoflurane have an impact on the basal and ATP-stimulated PTS. Avertin® PTS reduced basal and ATP-stimulated PTS decreased its presence in wild-type (WT) mice. Avertin® basal PTS-induced reduction in the WT mi...
