Logáil Isteach / Cláraigh

Terminal carbohydrate structures of sialomucin in the murine nasal cavity were characterized by means of lectin histochemistry. Two kinds of biotinylated lectins (Maackia amurensis agglutinin and Sambucus nigra agglutinin), which recognize sialic acid residues, showed marked differences in their

Recent in vitro studies have suggested a role for sialylation in chemokine receptor binding to its ligand (Bannert, N., S. Craig, M. Farzan, D. Sogah, N.V. Santo, H. Choe, and J. Sodroski. 2001. J. Exp. Med. 194:1661-1673). This prompted us to investigate chemokine-induced leukocyte adhesion in

OBJECTIVE The nasal and sinus cavities in children may serve as reservoirs for microorganisms that cause recurrent and chronic lung infections. This study evaluates whether the mink can be used as an animal model for studying Pseudomonas aeruginosa mediated rhino-sinusitis since there is no suitable

Histamine release induced by plant lectins was studied with emphasis on the carbohydrate specificity, external calcium requirement, metal binding sites, and mast cell heterogeneity and on the importance of antibodies bound to the mast cell membrane to the lectin effect. Peritoneal mast cells were

Differences in cell surface carbohydrates, and in laminin and fibronectin synthesis, between adherent and non-adherent Ehrlich ascites tumor cells.

Differences in cell surface carbohydrates and in laminin and fibronectin synthesis between 2 Ehrlich ascites tumor (EAT) cell lines, the adherent and non-adherent EAT cells, have been studied. The adherent EAT (a-EAT) cells grow in monolayer in vitro in the presence of fetal bovine serum. The

Wild-type and cultured Ehrlich ascites tumour cells differ in tumorigenicity, lectin binding patterns and binding to basement membranes.

Three different variants of the Ehrlich ascites tumour (EAT) cell were derived and the lectin surface reactivities, as well as the malignant characteristics of each variant, were studied. Wild-type cells (EAT-wt) were selected for growth on basement membranes and tissue culture plastic to give EAT-c

Differential expression of cell surface sialoglycoconjugates on wild-type and cultured Ehrlich tumor cells as revealed by quantitative lectin-gold ultrastructural cytochemistry.

Three variants of the classical Ehrlich ascites tumor (EAT) cell have been studied by quantitative, sialic acid-specific, lectin-gold ultrastructural cytochemistry. Electron microscopic examination revealed pronounced differences in the surface morphology of the three cell variants. The wild-type

Differences in sialic acid-galactose linkages in the chicken egg amnion and allantois influence human influenza virus receptor specificity and variant selection.

Logáil Isteach / Cláraigh

Human influenza viruses are more efficiently isolated by inoculating patient samples into the amniotic rather than the allantoic cavity of embryonated chicken eggs. This type of cultivation selects virus variants with mutations around the hemagglutinin (HA) receptor binding site. To understand the

Sialoglycoproteins and penultimate sugar expression pattern in developing murine olfactory and respiratory mucosa.

Logáil Isteach / Cláraigh

Sialic acid residues are constant constituents of the glycoproteins of the airways in all species. Sialoglycoproteins are the main acidic glycoprotein and their functions are to mediate cell adherence, to control the viscoelasticity of mucus and to serve as receptor sites for the binding of
