Lateral intercellular space volume as a determinant of CFTR-mediated anion secretion across small intestinal mucosa.


Studies of full-thickness, small intestinal preparations have shown that maximal anion secretion [indexed by short-circuit current (I(sc))] during intracellular cAMP (cAMP(i)) stimulation is transient and followed by a decline toward baseline. Declining I(sc) is preceded by decreases in transepithelial conductance (G(t)), which in the small intestine… (More)
