Figure 6. CFTR‐regulated, pendrin‐dependent apical HCO3 efflux is unaffected by hypercapnia .

Figure 6

A, a representative pHi experiment in which the effect of acute hypercapnia on 5 μm forskolin‐stimulated, CFTR‐regulated apical HCO3 transport was assessed by removal and subsequent re‐addition of apical Cl. B, ΔpH in response to removal of Cl. C and D, rate of re‐acidification (C) and HCO3 flux resulting from re‐addition of apical Cl (D). Data represent mean ± SEM; n = 6 for each.
