Thyroid hormone modulates rabbit proximal straight tubule paracellular permeability.
Proximal straight tubules (PST) from both neonatal and hypothyroid adult rabbits have a lower rate of passive volume absorption when perfused with a high-chloride solution simulating late proximal tubular fluid than adult rabbit PST. We hypothesized that the maturational increase in serum thyroid hormone levels mediates the developmental changes in PST paracellular permeability. Neonatal tubule...
متن کاملDevelopmental changes in rabbit proximal straight tubule paracellular permeability.
The early proximal tubule preferentially reabsorbs organic solutes and bicarbonate over chloride ions, resulting in a luminal fluid with a higher chloride concentration than that in blood. From this late proximal tubular fluid, one-half of NaCl reabsorption by the adult proximal tubule is active and transcellular and one-half is passive and paracellular. The purpose of the present in vitro micr...
متن کاملChannel-forming peptide modulates transepithelial electrical conductance and solute permeability.
NC-1059, a synthetic channel-forming peptide, transiently increases transepithelial electrical conductance (g(TE)) and ion transport (as indicated by short-circuit current) across Madin-Darby canine kidney (MDCK) cell monolayers in a time- and concentration-dependent manner when apically exposed. g(TE) increases from <2 to >40 mS/cm(2) over the low to middle micromolar range. Dextran polymer (9...
متن کاملRetinoids modulate P2Upurinergic receptor-mediated changes in transcervical paracellular permeability.
In human cervical cells, extracellular ATP induces an acute decrease in the resistance of the lateral intercellular space, the phase I response, followed by a delayed increase in tight junctional resistance, the phase II response. These responses depend on vitamin A because incubation of cells in retinoid-free medium (RFM) abolished both responses. Treatment with retinoic acid restored the phas...
متن کاملPseudo-streaming potentials in Necturus gallbladder epithelium. I. Paracellular origin of the transepithelial voltage changes
Apparent streaming potentials were elicited across Necturus gallbladder epithelium by addition or removal of sucrose from the apical bathing solution. In NaCl Ringer's solution, the transepithelial voltage (Vms) change (reference, basolateral solution) was positive with sucrose addition and negative with sucrose removal. Bilateral Cl- removal (cyclamate replacement) had no effect on the polarit...
