... epithelial barrier dysfunction. Methods: Adult rats were treated with water-avoid-stress. The serum levels of PRL were determined by ELISA. T84 cell (T84 cells; a vaginal epithelial cell line) monolayers were prepared to be used assessing the epithelial barrier functions. The expression of occludin in T84...

... on some members of the Na + /H + exchanger family (NHEs), as well as to clarify its consequences on transepithelial fluid flow in T84 cells. In order to do so, transepithelial fluid flow (J v ) was studied by optic techniques and intracellular pH (pH i ) was measured with a fluorescence method. Results...

...Meiqiu Lin; Katrina MacLeod; Sandra Guggino Heat-stable toxin (STa) increases cyclic GMP (cGMP) in isolated intestinal cells and in T84 cells, a colonic secretory cell line. Whole-cell current recordings from patch clamp experiments show identical properties for currents activated by either STa...
