Detection of a human autoantibody against intercalated cells of kidney-collecting tubule

Journal of Autoimmunity, 1989
Serum from a 24-year-old woman with a history of habitual abortions was examined for autoantibodies by indirect immunofluorescence microscopy. Fluorochrome-labelled antibodies to IgG revealed cytoplasmic staining of single cells in rat kidney collecting and connecting tubules.

Control of bicarbonate transport in collecting tubules from normal and remnant kidneys

American Journal of Physiology-Renal Physiology, 1989
Bicarbonate transport in the rabbit cortical collecting tubule (CCT) and outer medullary collecting tubule (MCT) in vitro was studied under two types of conditions that were anticipated to alter distal tubule bicarbonate transport: 1) reduction of renal mass, and 2) acid and base loading in vivo.

Specific plasma membrane differentiations in the cells of the kidney collecting tubule

Journal of Ultrastructure Research, 1975
Two types of membrane differentiations were observed by freeze-etching in the cells of the rat kidney collecting tubule. One consists of rectangular arrays of small (70 A) membrane-associated particles and is found in the light cells; the other is represented by particles with an elongated shape measuring about 290 × 160 A and is found in the membrane ...

Endosomes from kidney collecting tubule cells contain the vasopressin-sensitive water channel

Nature, 1988
The mechanism by which vasopressin rapidly and dramatically increases the water permeability of target epithelial cell membranes is thought to involve a cycle of exo- and endocytosis during which vesicles carrying 'water channels' are successively inserted into, and removed from the apical plasma membrane of epithelial cells.

Cloning and expression of apical membrane water channel of rat kidney collecting tubule

Nature, 1993
Concentrating urine is mandatory for most mammals to prevent water loss from the body. Concentrated urine is produced in response to vasopressin by the transepithelial recovery of water from the lumen of the kidney collecting tubule through highly water-permeable membranes.

Bicarbonate transport in collecting tubules from outer stripe of outer medulla of rabbit kidneys

American Journal of Physiology-Renal Physiology, 1987
The purpose of this study is to characterize the features of bicarbonate (total CO2) transport in isolated perfused collecting tubules obtained from the outer stripe of the outer medulla (OMCTos) of rabbit kidneys. Under control conditions (25 mM HCO3- in the perfusate and bath), all OMCTos studied absorbed total CO2 at a mean rate of 8.61 +/- 0.44 ...

Relationship between vasopressin-sensitive water transport and plasma membrane fluidity in kidney collecting tubule

American Journal of Physiology-Cell Physiology, 1991
The role of plasma membrane fluidity in the regulation of kidney tubule water permeability has been uncertain. We have used new methods to image the fluorescence anisotropy of fluidity-sensitive fluorophores (Fushimi, Dix, and Verkman. Biophys. J.

Similar chloride channels in the connecting tubule and cortical collecting duct of the mouse kidney

American Journal of Physiology-Renal Physiology, 2006
Using the patch-clamp technique, we investigated Cl−channels on the basolateral membrane of the connecting tubule (CNT) and cortical collecting duct (CCD). We found a ∼10-pS channel in CNT cell-attached patches. Substitution of sodium gluconate for NaCl in the pipette shifted the reversal potential by +25 mV, whereas N-methyl-d-gluconate chloride had ...

BONE AND CALCULI IN THE COLLECTING TUBULES OF THE KIDNEY

Archives of Surgery, 1933
In this paper the occurrence of bone in the human kidney in close association with parenchymatous stones will be described and its bearing on the theory of osteogenesis pointed out. The occurrence of bone in the kidney under experimental conditions has attracted much study since the original demonstration by Sacerdotti and Frattin 1 (1901).
