Abstract:

Objective To investigate the effects of nitric oxide(NO) signal pathway on ciliary beat frequency(CBF) in mouse nasal epithelial cells.
Methods Cultured mouse nasal epithelial cells were treated with 10 mmol/L L-arginine, the CBF was measured by high-speed digital microscopy. In addition, expression of endothelial nitric oxide synthase(eNOS), guanylate cyclase(GC) and protein kinase G(PKG) were detected by immunohistochemistry.
Results ① CBF of epithelial cells in Hank’s balanced salt solution(HBSS) control group showed no significant changes in 10 min. ② CBF increased with treatment of 10 mmol/L L-arginine at 2 min and significant changes were observed at all the time points detected. ③ Immunoreactivity to eNOS, GC and PKG were observed in cilia of epithelial cells.
Conclusion NO-cGMP-PKG signal pathway participates in the regulating mechanism of ciliary motility in mouse nasal epithelial cells.
