Review: Placental syncytiotrophoblast membranes e domains, subdomains and microdomains
(Elsevier, 2011)
Human placental syncytiotrophoblast (STB) is an epithelium responsible for materno-fetal exchange. Ions
play multiple roles in STB, as in other transport epithelia. We have been interested in the character and
functional ...
Iron supply determines apical/basolateral membrane distribution of intestinal iron transporters DMT1 and ferroportin 1
(2010)
00168.2009.—Intestinal iron absorption comprises
the coordinated activity of the influx transporter divalent metal
transporter 1 (DMT1) and the efflux transporter ferroportin (FPN). In
this work, we studied the movement ...
Proteomic analysis of apical microvillous membranes of syncytiotrophoblast cells reveals a high degree of similarity with lipid rafts
(AMER CHEMICAL SOC, 2005-11)
Brush borders (microvilli) are cell membrane specialized structures that function mainly as high-throughput absortive/secretory areas. It has been well-established that brush borders are particularly rich in membrane lipids ...
Distinct Lipid Rafts in Subdomains from Human Placental Apical Syncytiotrophoblast Membranes
(SPRINGER, 2008-08)
We report on the characteristics of raft domains in the apical membrane from human placental syncytiotrophoblast (hSTB), an epithelium responsible for maternal-fetal exchange. Previously, we described two isolated fractions ...
Expression and distribution of nucleoside transporter proteins in the human syncytiotrophoblast
(2011)
The plasma membrane distribution and related biological activity of nucleoside transporter proteins (NTs) were investigated in human syncytiotrophoblast from term placenta using a variety of approaches, including nucleoside ...
A method for analysis of lipid vesicle domain structure from confocal image data
(Springer, 2011-11-09)
Quantitative characterization of the lateral
structure of curved membranes based on fluorescence
microscopy requires knowledge of the fluorophore distribution
on the surface. We present an image analysis
approach for ...
Post-testicular changes in the density and distribution of intramembrane particles of stallion sperm surface domains
(2007)
Freeze-fracture replicas of stallion spermatozoa, collected from the proximal caput, corpus and cauda epididymides regions, were analyzed by electron microscopy to explore the distribution and density of intramembrane ...
Lipid Metabolizing Enzyme Activities Modulated by Phospholipid Substrate Lateral Distribution
(2011)
Biological membranes contain many domains enriched in phospholipid lipids and there is not yet clear explanation about how these domains can control the activity of phospholipid metabolizing enzymes. Here we used the surface ...
Cellular localization of TWIK-1, a two-pore-domain potassium channel in the rodent inner ear
(Elsevier, 2003)
K+ channels in the inner ear regulate the secretion and homeostasis of K+, i.e. the flux of K+ ions required to ensure good mechanosensory transduction. We studied the expression and cellular localization of TWIK-1 and ...
Preferential Protection of Domains II and III of Bacillus thuringiensis Cry1Aa Toxin by Brush Border Membrane Vesicles
(2010-12)
The surface exposed Leucine 371 on loop 2 of domain II, in Cry1Aa toxin, was mutated to Lysine to generate the trypsin-sensitive mutant, L371K. Upon trypsin digestion L371K is cleaved into approxima-tely 37 and 26 kDa ...
