BACKGROUND Hydatidiform moles carry a significant risk for developing persistent gestational trophoblastic disease. Lectins are useful tools to identify cellular glycosylation pattern and changes in glycosylation that occur during growth, development, differentiation and also, during disease states. OBJECTIVES Considering the changes in glycosylation that occur during cell proliferation, diff...

Carbohydrates and protein glycoconjugates on the cell membranes of Cryptobia salmositica, C. bullocki and C. catostomi were analyzed using 13 highly purified lectins (unlabelled or digoxigenin/biotin labelled). No agglutinations were observed with C. salmositica, C. bullocki and C. catostomi using lectin TPA (Tetragonolobus purpureas agglutinin, for alpha-L-fucose). C. salmositica was agglutina...

1. A method which allows the characterization of lectin-binding components is described. This method should be useful in defining the nature and heterogeneity of these components in cell membranes. 2. The method, which we have used on erythrocyte "ghosts", involves the fixation of "ghost" components after sodium dodecyl sulphate/polyacrylamide-gel electrophoresis and incubation with purified 12...

Lectins are carbohydrate-binding proteins widely distributed in nature. They constitute a highly diverse group of proteins consisting of many different protein families that are, in general, structurally unrelated. In the last few years, mushroom and other fungal lectins have attracted wide attention due to their antitumour, antiproliferative and immunomodulatory activities. The present mini-re...

Gastroenteritis in piglets after weaning is a common disease that significantly reduces feeding efficiency, impairs performance and leads to financial losses. In this paper, we have proposed method for the prevention of gastroenteritis by neutralizing provender lectins with glucosamine (GluA). Lectin proteins are anti-nutritional factors one etiological causing gastroenteritis. our vitro experi...

Lectins are a structurally diverse class of (glyco)proteins which bind mono- and oligosaccharides with high specificity and in a reversible way. For many years, the unique sugar binding properties of plant lectins have been exploited for the development of biochemical tools for glycoprotein isolation and characterisation, and the use of lectins as a glycoprofiling tool has became much more soph...

Lectins that target N-glycans on the surface of HIV-1 envelope (Env) glycoprotein have the potential for use as antiviral agents. Although progress has been made in deciphering the molecular details of lectin and Env glycan interaction, further studies are needed to better understand Env glycan heterogeneity among HIV-1 isolates and its influence on virus-neutralization sensitivity to lectins. ...

Because of the antimicrobial resistance crisis, lectins are considered novel drug targets. Pseudomonas aeruginosa utilizes LecA and LecB in infection process. Inhibition both with carbohydrate-derived molecules can reduce biofilm formation to restore susceptibility. Here, we focused on non-carbohydrate inhibitors for explore new avenues lectin inhibition. From a screening cascade obtained one e...
