The specificity of frutalin lectin using biomembrane models
(ELSEVIER SCIENCE BV, 2010)
Frutalin is a homotetrameric alpha-D-galactose (D-Gal)-binding lectin that activates natural killer cells in vitro and promotes leukocyte migration in vivo. Because lectins are potent lymphocyte stimulators, understanding ...
Cloning and functional characterization of two key enzymes of glycosphingolipid biosynthesis in the amphibian Xenopus laevis
(Wiley-liss, Div John Wiley & Sons Inc, 2008-01)
Gangliosides are a subfamily of complex glycosphingolipids (GSLs) with important roles in many biological processes. In this study, we report the cDNA cloning, functional characterization, and the spatial and temporal ...
Uptake of oxLDL and IL-10 production by macrophages requires PAFR and CD36 recruitment into the same lipid rafts
(Public Library of ScienceSan Francisco, 2013-10-09)
Macrophage interaction with oxidized low-density lipoprotein (oxLDL) leads to its differentiation into foam cells and cytokine production, contributing to atherosclerosis development. In a previous study, we showed that ...
A highly stable, non-digestible lectin from Pomacea diffusa unveils clade-related protection systems in apple snail eggs
(Company of Biologists, 2020-10-08)
The acquisition of egg protection is vital for species survival. Poisonous eggs from Pomacea apple snails have defensive macromolecules for protection. Here we isolated and characterized a novel lectin called PdPV1 that ...
Cholesterol Depletion Disorganizes Oocyte Membrane Rafts Altering Mouse Fertilization
(Public Library of Science, 2013-04-25)
Drastic membrane reorganization occurs when mammalian sperm binds to and fuses with the oocyte membrane. Two oocyte protein families are essential for fertilization, tetraspanins and glycosylphosphatidylinositol-anchored ...
Free cholesterol and cholesterol esters in bovine oocytes: Implications in survival and membrane raft organization after cryopreservation
(Public Library of Science, 2017-07-07)
Part of the damage caused by cryopreservation of mammalian oocytes occurs at the plasma membrane. The addition of cholesterol to cell membranes as a strategy to make it more tolerant to cryopreservation has been little ...
Free cholesterol and cholesterol esters in bovine oocytes: Implications in survival and membrane raft organization after cryopreservation
(2017)
Part of the damage caused by cryopreservation of mammalian oocytes occurs at the plasma
membrane. The addition of cholesterol to cell membranes as a strategy to make it more tolerant
to cryopreservation has been little ...

Secondary Metabolites of Biological Significance from Echinoderms
(CRC Press - Taylor & Francis Group, 2014)
The extraordinary development of marine natural products chemistry during the last three decades has been prompted by the fact that marine organisms are sources of new natural products with unusual structural features that ...
Lipid Rafts and Cytoskeletal Proteins in Placental Microvilli Membranes from Preeclamptic and IUGR Pregnancies
(Springer, 2011-05)
Intrauterine growth restriction (IUGR) and preeclampsia (PE) are leading causes of perinatal and maternal morbidity and mortality. Previously we reported the expression of lipid rafts in classical microvillous membrane ...
