A: isoproterenol (ISO)-stimulated ciliary beat frequency (CBF) in MTRs is concentration dependent. WT MTRs were stimulated with various concentrations of ISO. Unstimulated CBF among each group was ∼9 Hz (○). ISO increased CBF by 30 min of exposure (14–16 Hz; ●; ***P < 0.001 vs. media control). B: ISO stimulates ciliary motility in MTRs and bovine bronchial epithelial cells (BBECs). Baseline CBF from both WT MTRs and ciliated BBECs were similar. ISO (10 μM) significantly stimulated CBF in both WT MTRs and ciliated BBECs over media control (4.85 ± 0.435 Hz and 4.975 ± 0.7763 Hz, respectively). All frequencies are expressed as means ± SE from 6 separate fields. These data are representative of 3 independent experiments (MTRs *P < 0.05 vs. media control; BBECs **P < 0.01 vs. media control).
