Characterization of Paracellular Permeability in Cultured Human Cervical Epithelium: Regulation by Extracellular Adenosine Triphosphate
Tóm tắt
The purpose of the present study was to compare the permeaiility and regulation of paracellular transport in human cervical cells with those in epithelial cells of other organs. Cervical cells (ECE16–1, Caski, and HT3) were grown on filters, and trans-epithelial electrical conductance (GT) and the permeability to pyranine (PPyr) were determined. Cervical cultures were characterized by high GT (83–125 mS•cm−2 ) and high PPyr (6.2–18•10−6 •sec−1). The GT was not significantly affected by cell density but was increased by 20% by lowering extracellular calcium to 0.45 mmol/L or less. The high values of GT and PPyr and the regulation by extracellular calcium indicate that all three cervical cell lines have “leaky” tight junctional complexes. Addition of extracellular adenosine triphosphate (ATP) at 50 μmol/L to the cervical cultures evoked a biphasic change in GT- that was unique to the cervical cells: an initial increase, followed by a sustained decrease by 30 /o frorn baseline GT. The decrease oj GT- was associated with a decrease in PPyr by 17%, indicating that ATP had an effect on the tight junctional/paracellular permeability. The ATP effect was reversible either by washing or by chemical hydrolysis with ATPse. 1 he non-cervical cell lines all responded to extracellular ATP with a transient increase in GT, but not with the pronounced decrease. The permeability of the paracellular pathway can be regulated in cervical epithelia by mechanisms that may be different frorn those in epithelial cells frorn other organs.
