Figure 1. Representative VTE recordings.
The recordings obtained with the final protocol are shown for WT (A) and cftr -/- B6;129 mice (B). Three phases was observed: baseline VTE after Cl- solution perfusion, VTEAmil. after the addition of amiloride (Amil.) and VTELowCl - after the replacement of Cl- solution with a solution of low Cl- concentration (LowCl-). The inhibitory effect on Cl- secretion of inhibitor-172 and inhibitor-172 plus DIDS was demonstrated in WT mice.
