The aim of this study was to examine the distribution glycoconjugates in conjunctival epithelium partridge (Alectoris chukar) and quail (Coturnix coturnix). Eyelid samples harvested from both species were subjected routine tissue processing. Lectin histochemistry applied sections order demonstrate expression glycoconjugates. Six different HRP-conjugated lectins (Con A, UEA-I, PNA, HPA, MAA BSA ...

A series of cyclodextrin-based glycoconjugates, including glycoclusters and star glycopolymers, were synthesized via combination of CuAAC Huisgen coupling and copper-mediated living radical polymerization. These glycoconjugates showed high affinity binding to the human transmembrane lectin DC-SIGN and act as inhibitors to prevent the binding of HIV envelope protein gp120 to DC-SIGN at nanomolar...

Lupeol, a pentacyclic triterpene, possesses diverse pharmacological and biochemical activities including anticancer and antioxidant effects. Abnormalities in the status of glycoconjugates and lipids in the cell results in malignant transformation. The aim of the present study was to investigate the protective effect of lupeol on cell surface glycoconjugates and lipids abnormalities during 7,12-...

Many pathogenic prokaryotes and eukaryotes possess the machinery required to assemble galactofuranose (Galf)-containing glycoconjugates; these glycoconjugates can be critical for virulence or viability. Accordingly, compounds that block Galf incorporation may serve as therapeutic leads or as probes of the function of Galf-containing glycoconjugates. The enzyme UDP-galactopyranose mutase (UGM) i...

It has been widely reported that the Harderian gland, present in most vertebrates, accumulates high levels of porphyrins, particularly protoporphyrin. The present study describes the extraction, identification and characterization of a group of hitherto unreported protoporphyrin glycoconjugates in the rat Harderian gland using HPLC, capillary electrophoresis, on-line HPLC/electrospray ionizatio...

Vaccination against the ubiquitous parasite Toxoplasma gondii would provide the most efficient prevention against toxoplasmosis-related congenital, brain and eye diseases in humans. We investigated the immune response elicited by pathogen-specific glycosylphosphatidylinositol (GPI) glycoconjugates using carbohydrate microarrays in a BALB/c mouse model. We further examined the protective propert...

1. The presence of a large amount of glycoconjugates on the anuran amphibian germ cells was demonstrated using fluorescein isothiocyanate lectins binding specifically to D-galactose and at a lower level, by other lectins binding specifically to iV-acetyl-galactosamine. 2. Glycoconjugates including D-galactose were found near the pseudopodial expansions and in the extracellular space, between ge...
