Distinct functions of Crumbs regulating slit diaphragms and endocytosis in Drosophila nephrocytes
Cellular and Molecular Life Sciences, 2017Mammalian podocytes, the key determinants of the kidney's filtration barrier, differentiate from columnar epithelial cells and several key determinants of apical-basal polarity in the conventional epithelia have been shown to regulate podocyte morphogenesis and function.

[Morphogenesis of nephrocyte dystrophy].
Arkhiv patologii, 1983Morphogenesis of dystrophy of nephrocytes was studied by analysis of 106 biopsies of kidneys from patients with glomerulonephritis using light (semi-thin sections) and electron microscopy. The development of one or another kind of nephrocyte dystrophy was shown to be due to the deficiency of certain mechanisms of renal reabsorption and secretion ...

Structural and Metabolic Characteristic of Nephrocytes during Peritonitis of Various Genesis
Bulletin of Experimental Biology and Medicine, 2001Structural and metabolic changes in nephrocytes during peritonitis were studied on early autopsy material. Unspecific morphological changes in the kidneys were presented by circulatory disturbances and damage to the tubular epithelium. The changes in dehydrogenase activity in nephrocytes of the proximal and distal tubules depended on the cause of ...

Cytochemical localization of calcium in renal sac nephrocytes of Helix aspersa
Tissue and Cell, 1989In renal sac nephrocytes of Helix aspersa, intracellular calcium has been localized using the oxalate-pyroantimonate (OPA) and phosphate-pyroantimonate (PPA) methods. Pyroantimonate precipitates are preferentially localized in the excretory spherule and in vesicles located in the basal and lateral regions of the nephrocyte.

Transformational process of the endosomal compartment in nephrocytes of Drosophila melanogaster
Cell and Tissue Research, 1990This study investigates by electron microscopy the transformational process of the endosomal compartment of the Drosophila nephrocyte, the garland cell, which occurs during endocytotic processing of internalized material. The endosomal compartment of the garland cell consists of a prominent tubular/vacuolar complex in the cortical cytoplasm.

Drosophila melanogaster and its nephrocytes: A versatile model for glomerular research
2019Glomerular disorders are a predominant cause of chronic kidney diseases and end-stage renal failure. Especially podocytes, epithelial cells which represent the outermost part of the filtration barrier, are affected by disease and experience a gradual loss of function. Despite recent advances in identifying potential pathways underlying podocyte injury,

Ultrastructure of gypsy moth (Lymantria dispar) nephrocytes
Proceedings, annual meeting, Electron Microscopy Society of America, 1992Nephrocytes are endocytotic cells that exist in distinct groups at fixed sites within the body cavity of arthropods. They can be identified by their uptake of the vital dye, Trypan blue. The only types of nephrocyte that have been described in the insect order Lepidoptera are the pericardial cells, which have been described in many species, and the ...

Nitrophenylphosphatase activity in the kidney sac nephrocytes of Helix aspersa.
Basic and applied histochemistry, 1985A cytochemical study of p-nitrophenylphosphatase activity in the renal sac of Helix aspersa was carried out, for which the organ was divided in three parts: posterior, middle and anterior. The apical, lateral and basal plasma membranes of the nephrocytes were shown to have both L-cysteine and ouabain sensitive phosphatase activities.
