C5aR Expression in Kidney Tubules, Macrophages and Fibrosis
Journal of Histotechnology, 2023The anaphylatoxin C5a and its receptor C5aR (CD88) are complement pathway effectors implicated in renal diseases, including ANCA-associated vasculitis. We investigated the kidney expression of C5aR and a second C5a receptor C5L2 by using immunohistochemistry and in situ hybridization on formalin-fixed, paraffin-embedded human and mouse kidney. C5aR was

On the mechanisms of transfilter induction of kidney tubules
Journal of Theoretical Biology, 1979Abstract Induction of tubule formation in metanephrogenic mesenchyme by spinal cord, occurs across 15 μm thick nucleopore filters with pores greater than 0·1 μm in diameter, but not when the pores are less than 0·05 μm. Processes from the inducer cells penetrate the 0·1 μm pores but not those of 0·05 μm diameter. These results are usually interpreted

Electrolyte transport in kidney tubule cells
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1971Abstract Transtubular movement of Na and K takes place across an electrically negative cell compartment rich in K and poor in Na. Some properties of the luminal and peritubular cell boundaries with respect to ionic pump and leak characteristics are analysed.

Isolation of viable rat kidney tubules
Life Sciences, 1971Abstract A method has been devised for the isolation of viable tubules from the rat renal cortex. More than 70% of the preparation consisted of fragments of proximal tubules which respired in calcium- and glucose-free buffer solution. The addition of glucose or succinate to the medium enhanced the oxygen uptake and allowed for a linear respiration ...

Wnts as kidney tubule inducing factors
The International Journal of Developmental Biology, 1999Since the discovery that inductive tissue interactions regulate nephrogenesis, one of the aims has been to identify the molecules that mediate this induction. The small size of embryonic tissue has limited the possibilities to identify the inducers biochemically, even though such efforts were directed to study, e.g.

Markers of Kidney Tubule Dysfunction and Major Adverse Kidney Events
Nephron, 2023<b><i>Background:</i></b> Serum creatinine and albuminuria are primary markers of glomerular function and injury, respectively. Tubular secretion, acid-base homeostasis, protein reabsorption, among other tubular functions, are largely ignored.

Acidification in the distal tubule of the Amphiuma kidney
Acta Physiologica Scandinavica, 1983The acidification of the urine within the distal tubule of Amphiuma means was studied with micropuncture techniques. Antimony microelectrodes calibrated in vivo were used for measuring the intratubular pH and samples were taken for the determination of Na+‐ and Cl‐‐concentrations and for determining buffer lines within the HCO‐3‐CO2 buffer system.

Lipids in the Proximal Tubules of the Kidney in Diabetic Coma
The American Journal of Forensic Medicine and Pathology, 2000Vacuolization of the renal tubular epithelial cells (the Armanni-Ebstein lesion) associated with diabetic hyperglycemia is usually regarded as an accumulation of glycogen. In a case of death of diabetic coma, the vacuoles were stained strongly for lipids.

Publisher Summary During the past few years kidney tubules have been submitted to several analyses with the aid of the electron microscope; analyses that provide information on the multitude of uncertainties associated with renal structures. The architecture of all the cells of the nephron is especially well adapted for the passage of fluid, a ...

Protein handling in kidney tubules
Nature Reviews NephrologyThe kidney proximal tubule reabsorbs and degrades filtered plasma proteins to reclaim valuable nutrients and maintain body homeostasis. Defects in this process result in proteinuria, one of the most frequently used biomarkers of kidney disease. Filtered proteins enter proximal tubules via receptor-mediated endocytosis and are processed within a highly ...
