Stimulus-Response Coupling in Mammalian Ciliated Cells: The Role of Ca2+ in Prostaglandin Stimulation
Calcium has been thought to play an important role in the control of ciliary movement in a broad variety of ciliated cells. In mammalian ciliated cells Ca2 + depletion can cause reversible ciliary arrest. Also, ciliostimulation produced by prostaglandins in ciliated cells of the oviduct is thought to be coupled by release of intracellular Ca2+. However, direct measurements of fluctuations of intracellular [Ca2+] associated with stimulation of ciliary activity have not been reported.
