Recently, we found that human anti-GlcNAc mAbs reacted with keratin from human skin and recognized specific peptide epitopes of human cytokeratin 14. Our data demonstrate that anti-keratin Ab responses in mice might be driven by Ags bearing terminal O-linked GlcNAc residues. To determine if mouse
Cell-surface carbohydrates of Entamoeba invadens trophozoites were analyzed using (a) a panel of highly purified lectins specific for molecules containing N-acetylglucosamine or sialic acid, N-acetylgalactosamine, galactose, mannose-like residues, and fucose; (b) Escherichia coli K-12 with
The turkey sperm glycocalyx is known to contain residues of sialic acid, alpha-mannose/alpha-glucose, alpha- and beta-galactose, alpha-fucose, alpha- and beta-N-acetyl-galactosamine, monomers and dimers of N-acetyl-glucosamine, and N-acetyl-lactosamine. Potential changes in these carbohydrates
Pneumocystis carinii obtained from infected rat lung homogenates was incubated with fluorescein isothiocyanate-conjugated lectins, counterstained with the nuclear stain, propidium iodide (PI), and analyzed by dual parameter histograms for lectin-associated green and PI-associated red fluorescence
BACKGROUND
Lactoferrin is an iron-binding protein belonging to the transferrin family. In addition to iron homeostasis, lactoferrin is also thought to have anti-microbial, anti-inflammatory, and anticancer activities. Previous studies showed that all lactoferrins are glycosylated in the human body,
1. Mannose-binding and N-acetylglucosamine binding lectins exhibited potent antilipolytic and lipogenic activities. 2. Fucose-binding lectins had minimal lipogenic activity but possessed antilipolytic activity. 3. Most galactose-binding and N-acetylgalactosamine-binding lectins were devoid of
The cochlear nucleus is made up of a number of diverse cell types with different anatomical and physiological properties. A plant lectin, Wisteria floribunda agglutinin, that recognizes specific carbohydrate residues in the extracellular matrix binds to some cell types in the ventral cochlear
BACKGROUND
Wisteria floribunda agglutinin (WFA)-sialylated mucin core polypeptide 1 (MUC1) was investigated as a new glycoprotein marker for cholangiocarcinoma (CC) using glycoproteomics technologies. In this multicenter study, WFA-sialylated MUC1 levels in serum and bile samples were measured to
OBJECTIVE
Serum
carbohydrate antigen 19-9 (CA19-9) is a widely used tumour marker for cholangiocarcinoma (CCA). However, it is not a necessarily good CCA marker in terms of diagnostic accuracy. The purpose of this study is to evaluate the diagnostic value of
WisteriaThe autoradiographic detection of 125I-labeled lectins binding to glycolipids on thin-layer chromatograms can be used to rapidly analyze total glycolipid extracts of cells or tissues for specific oligosaccharide structures. The Helix pomatia lectin which binds with high affinity to terminal
The binding characteristics of a panel of commercially available FITC-conjugated lectins to Pneumocystis carinii (Pc) were assessed by fluorescence microscopy and flow cytometry. Rat Pc obtained from infected lung homogenates were incubated with FITC-conjugated lectins in a series of concentrations,
Aberrant glycosylation and the overexpression of specific carbohydrate epitopes is a hallmark of many cancers, and tumor-associated oligosaccharides are actively investigated as targets for immunotherapy and diagnostics. Wisteria floribunda agglutinin (WFA) is a legume lectin that recognizes
In order to study the role of the asialoglycoprotein receptor (ASGPr) in the rapid plasma clearance of urokinase-type plasminogen activator (u-PA), a microtiter plate binding assay was developed using ASGPr purified from rat liver extracts. Urinary two-chain u-PA bound to immobilized ASGPr in a
Cell surface glycoconjugates have been implicated in the growth and guidance of subpopulations of primary olfactory axons. While subpopulations of primary olfactory neurons have been identified by differential expression of carbohydrates in the rat there are few reports of similar subpopulations in
Alterations in cortical parvalbumin (PV)-containing neurons, including a reduced density of detectable neurons and lower PV levels, have frequently been reported in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia subjects. Most PV neurons are surrounded by perineuronal nets (PNNs) and
