Molecular organization of the intestinal brush border
Biochimie, 1988The brush border of enterocytes represents one of the more specialized apical poles of epithelial cells. It is formed by particularly well-developed apical plasma membrane microvilli, whose shape is ensured by a highly organized cytoskeleton. The molecular organization of the cytoskeleton is described.

Human Intestinal Brush Border Peptidases
Gastroenterology, 1985Hydrolysis of small peptides, like disaccharide hydrolysis, is an important function of the intestinal brush border, but little is known of the individual human peptidases. The purposes of this study were to detect all human brush border enzymes hydrolyzing dipeptides and tripeptides, identify the most discriminating substrate for each enzyme in order ...

Intestinal Brush Border Membrane Function
Scandinavian Journal of Gastroenterology, 1994The gastrointestinal tract is a complex organ responsible for. for example, nutrient metabolism, absorption and transport. and hormonal production and action. Furthermore, it serves as an immune barrier against invasion of enteric bacteria and toxins.

Endocytic trafficking from the small intestinal brush border probed with FM dye.
American Journal of Physiology - Gastrointestinal and Liver Physiology, 2009The small intestinal brush border functions as the body's main portal for uptake of dietary nutrients and simultaneously acts as the largest permeability barrier against pathogens.

Introductory remarks on the brush border.
Ciba Foundation symposium, 1983The specialized surface of the luminal border of small intestinal epithelial cells was first described by J. Henle in 1837 and for many years controversy raged about the nature of this region. Was it a plate rendered porous by perforating canals or was it composed of an array of rods with their long axes normal to the surface?

Endocrinology, 1978
Insulin receptor characteristics were examined in purified brush border membrane from the syncytiotrophoblast of the normal human placenta and quantified during membrane preparation. Insulin receptor concentration was enriched 10- to 15-fold in this preparation, and insulin receptor specific activity followed closely the enrichment values for ...

Age-Related Changes in Renal Brush Borders and Brush Border Enzymes
1989The ageing process leads to a deterioration of function in most body organs. Much attention has been paid to studying the effect of ageing on the kidney. These changes are both structural and functional. Thus far, the structural changes of kidney during ageing has been extensively studied (1,2), the number of glomeruli decreasing with age.

The histochemical demonstration of brush border endopeptidase
Histochemistry, 1979A histochemical method for the demonstration of a brush border endopeptidase is described based on results of biochemical and histochemical experiments. The substrate of choice is Glut-Ala-Ala-Ala-MNA which displays a very good localization ability and suitable kinetic properties. Km estimated in rat kidney homogenate amounts to 2.35 X 10(-4) M.

NHE3: a Na+/H+ exchanger isoform of renal brush border.
American Journal of Physiology, 1993Na+/H+ exchangers in the brush-border (luminal, apical) membrane of renal proximal tubules are responsible for active, transcellular reabsorption of NaHCO3 and NaCl.
