A panel of fifteen biotinylated lectins was used to study the saccharides associated with the epithelial component of normal and leukoplakic mucosa and squamous cell carcinoma, from a variety of locations in the oral cavity. Lectin binding heterogeneity was found between various sites of normal

A 60-kilodalton glycoprotein previously isolated and purified from human saliva (J. B. Babu, E. H. Beachey, D. L. Hasty, and W. A. Simpson, Infect. Immun. 51: 405-413, 1986) was found to interact with type 1 fimbriae and prevent adhesion of type 1 fimbriated Escherichia coli to animal cells in a

A total of 27 bacterial isolates from California sea lions and a walrus tentatively classified within the family Pasteurellaceae was further characterized by genotypic and phenotypic tests. Phylogenetic analysis of partial 16S rRNA and rpoB gene sequences showed that the isolates investigated formed

BACKGROUND The D-mannose binding lectin ArtinM is known to recruit neutrophils, to degranulate mast cells and may have potential therapeutic applications. However, the effect of ArtinM on mast cell recruitment has not been investigated. METHODS Male Wistar rats were injected i.p. with ArtinM or ConA

We recently established that an increased expression of alpha-D-mannose (Man)- and beta-D-galactose-rich plasma membrane glycoproteins (GPs) is characteristic for apoptotic cells in vitro [Bilyy, R.O., Stoika, R.S., 2003. Lectinocytochemical detection of apoptotic murine leukemia L1210 cells.

Using polarizable molecular mechanics, a recent study [de Courcy et al. J. Am. Chem. Soc., 2010, 132, 3312] has compared the relative energy balances of five competing inhibitors of the FAK kinase. It showed that the inclusion of structural water molecules was indispensable for an ordering

The in vitro uptake study was performed using the isolated cells of human oral mucosa, buccal and the dorsum of the tongue, to investigate the mechanisms of glucose uptake. The uptake of D-glucose was much larger in cells of the dorsum of the tongue than in buccal cells and was inhibited more

The effect of tumor cells and immunostimulants on the release of cytostatic factors (CF) from Lactobacillus casei YIT 9018 (LC)-, Corynebacterium parvum (CP)- or peptone-elicited peritoneal macrophages (PM) was investigated in vitro and in vivo. Significant release of CF into the culture medium from

Lectins represent a class of proteins or glycoproteins capable of reversibly binding to carbohydrates. Seed lectins from the Dalbergieae tribe (Leguminosae) have structural variability, carbohydrate specificity, and biological effects, such as inflammation, vasorelaxation and cancer antigen binding.

A novel lectin from Talisia esculenta seeds (TEL) has recently been purified and characterized. In this study we investigated the proinflammatory activity of TEL in mice using both the air-pouch and peritoneal cavity as well as paw oedema models. TEL (10-40 microg) induced significant neutrophil and

We investigated the effect of Helianthus tuberosus agglutinin (HTA) on neutrophil migration in vivo and in vitro. The role of resident cells in this effect was analyzed. Peritonitis was induced by injecting stimuli into rat (150-200 g) peritoneal cavities, and in vitro neutrophil chemotaxis was

OBJECTIVE Since some plant and mammalian lectins specific for monosaccharides are able to induce neutrophil migration, we studied the neutrophil migration-inducing activities of marine algal lectins, specific for complex oligosaccharides from glycoproteins, from Amansia multifida (AM), Bryothamnion

A lectin histochemical study was performed to investigate the distribution and changes of the oligosaccharidic component of the glycoconjugates in the lung of chick embryos, of 1-day-old chick, and of the adult animal. For this purpose, a battery of seven horseradish peroxidase-conjugated lectins

In 2007, a new bacterial disease was observed in greenhouse-cultivated cherry tomatoes in Cheorwon and Iksan provinces, Korea. The disease caused severe wilt of tomatoes (Solanum lycopersicum cv. Koko). Infected young petioles were curled downward. Margins of the leaves rolled upward and whole

Surfactant protein A (SP-A), a C-type lectin, plays an important role in innate lung host defense against inhaled pathogens. Crystallographic SP-A·ligand complexes have not been reported to date, limiting available molecular information about SP-A interactions with microbial surface components. This
