Ciliary Beat

The intent of this work was to evaluate the role of cAMP in regulation of ciliary activity in frog mucociliary epithelium and to examine the possibility of cross talk between the cAMP- and Ca2+-dependent pathways in that regulation. Forskolin and dibutyryl cAMP induced strong transient intracellular Ca2+ concentration ([Ca2+]i) elevation and strong ciliary beat frequency enhancement with prolonged stabilization at an elevated plateau. The response was not affected by reduction of extracellular Ca2+concentration. The elevation in [Ca2+]iwas canceled by pretreatment with 1,2-bis(2-aminophenoxy)ethane- N, N, N′, N′-tetraacetic acid-AM, thapsigargin, and a phospholipase C inhibitor, U-73122. Under those experimental conditions, forskolin raised the beat frequency to a moderately elevated plateau, whereas the initial strong rise in frequency was completely abolished. All effects were canceled by H-89, a selective protein kinase A (PKA) inhibitor. The results suggest a dual role for PKA in ciliary regulation. PKA releases Ca2+ from intracellular stores, strongly activating ciliary beating, and, concurrently, produces moderate prolonged enhancement of the beat frequency by a Ca2+-independent mechanism.

Ciliary Beat

Ciliated airway epithelial cells contribute to mucociliary transport systems via ciliary beating and electrolyte transport mechanisms. Both of these activities are regulated by agonists acting through intracellular calcium- and adenosine 3',5'-cyclic monophosphate (cAMP)-dependent processes (5, 15, 18, 27). This study examines the role of guanosine 3',5'-cyclic monophosphate (cGMP) in the regulation of both ciliary beat frequency (CBF) and electrolyte transport in human airway epithelia (HAE). In a previous report, cGMP production in HAE was observed after stimulation with either C-type natriuretic peptide (CNP) or sodium nitroprusside (SNP) (6). In this study, CNP was found to increase CBF by 30 +/- 6.9%, and this effect was mimicked by the cGMP analogue, 8-bromoguanosine 3',5'-cyclic monophosphate (8-BrcGMP), but not by sodium nitroprusside. CNP-induced increases in CBF do not appear to be mediated by changes in either intracellular calcium or cAMP levels. Using modified Ussing chambers, we also investigated CNP's potential modulation of sodium and chloride transport rates. Neither CNP, nor SNP, nor 8-BrcGMP altered active ion transport rates. We conclude that CNP regulates ciliary beat via cGMP-dependent mechanisms, whereas no effect of CNP or cGMP on ion transport was detected.

Ciliary Beat

Ciliary beating is required for the maintenance of lung mucociliary transport. We investigated the role of cyclic nucleotide-dependent protein kinases in stimulating ciliary beat frequency (CBF) in bovine bronchial epithelial cells (BBECs). cAMP-dependent protein kinase (PKA) activity and cGMP-dependent protein kinase (PKG) activity were distinguished after DEAE-Sephacel chromatography of BBEC extracts. cAMP levels and PKA activity are increased in BBECs stimulated with 0.01–1 mM isoproterenol, with a corresponding increase in CBF. cGMP levels and PKG activity are increased in BBECs stimulated with 0.1–10 μM sodium nitroprusside, with a corresponding increase in CBF. Direct protein kinase-activating analogs of cAMP and cGMP (dibutyryl cAMP and 8-bromo-cGMP, respectively) also activate their specific kinases and stimulate CBF. Preincubation of BBECs with inhibitors of PKA or PKG [KT-5720 or Rp-8-( p-chlorophenylthio)-guanosine 3′,5′-cyclic monophosphothioate] results in the inhibition of specific kinase activity as well as in the inhibition of CBF. These studies suggest that the activation of either PKA or PKG can lead to the stimulation of CBF in bovine airway epithelium.
