Figure 3. Quercetin (10 μM) activates ciliary beat frequency following apical, but not basolateral exposure.

(A) CBF was significantly increased following quercetin (10 μM) addition to the apical surface when compared to controls (PBS) (p<0.01). Alternate agents that directly activate CBF through P2Y2 receptors (UTP, 150 μM) or cAMP (forskolin, 100 nM) are shown for comparison. All measurements were recorded following 15 minutes of exposure. (B) Quercetin administered to the basal media demonstrated no significant increase in CBF following acute administration (15 minutes) (p=0.64) or longer duration (90 minutes) (p=0.93).
