The Drosophila nephrocyte [PDF]
Current Opinion in Nephrology and Hypertension, 2011 The functioning kidney requires proper organization in multiple cell types that mediate filtration and removal of wastes. Interest has increasingly focused on the podocyte as an important mediator of kidney function; defects in podocyte function likely mediate a broad palate of kidney dysfunctions.

The insect nephrocyte is a podocyte-like cell with a filtration slit diaphragm [PDF]
Nature, 2008 The nephron is the basic structural and functional unit of the vertebrate kidney. It is composed of a glomerulus, the site of ultrafiltration, and a renal tubule, along which the filtrate is modified. Although widely regarded as a vertebrate adaptation, 'nephron-like' features can be found in the excretory systems of many invertebrates, raising the ...

Drosophila pericardial nephrocyte ultrastructure changes during ageing [PDF]
Mechanisms of Ageing and Development, 2018 Here we show that a labyrinth channel compartment and slit diaphragms, which are the histological structures enabling insect nephrocytes ultrafiltration, are established during embryogenesis first by the garland nephrocytes (GCNs). The later pericardial nephrocytes, which represent the majority of functional nephrocytes in larvae and adults, lack these

Insect nephrocyte function is regulated by a store operated calcium entry mechanism controlling endocytosis and Amnionless turnover [PDF]
Journal of Insect Physiology, 2022 Insect nephrocytes are ultrafiltration cells that remove circulating proteins and exogenous toxins from the haemolymph. Experimental disruption of nephrocyte development or function leads to systemic impairment of insect physiology as evidenced by ...

Impact of cypermethrin in nephrocytes of freshwater fish Catla catla
Environmental Toxicology and Pharmacology, 2021The kidney of Catla catla, chronically exposed to sub-lethal concentrations (0.24 μg/L and 0.41 μg/L) of cypermethrin revealed a significant elevation in the activity of antioxidants superoxide dismutase (SOD), catalase (CAT), glutathione-s-transferase (GST) and reduced glutathione (GSH) after 15 days, followed by a decline of up to 45 days.

Location, morphology and function of nephrocytes in termites
Arthropod Structure & Development, 2015Insect nephrocytes are cells bathed in hemolymph and considered to have an excretory function. These cells have ambiguous nomenclature and are understudied in termites. This study is the first report on the occurrence, morphology and function of nephrocytes in different termite castes.

Using Drosophila nephrocytes in genetic kidney disease
Cell and Tissue Research, 2017Renal diseases are a growing health burden, and innovative models to study their pathomechanisms are greatly needed. Here, we highlight how the fruit fly Drosophila melanogaster can be used to model kidney diseases. We focus on the nephrocyte that has recently been shown to exhibit podocyte and proximal tubular cell features.

Nephrocytes of harvestmen, Leiobunum limbatum and L. rotundum
Tissue and Cell, 1991Nephrocytes are said to be able to take up substances from the hemolymph. In Opiliones, which were examined electron microscopically three different types of nephrocytes were found. Numerous large nephrocytes lie clustered between the muscles in the anterior region of the body.

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.

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 ...
