Classes of intracellular lectins that recognize core-type structures and mediate intracellular glycoprotein trafficking are present in vertebrates, model invertebrates such as Caenorhabditis elegans and Drosophila melanogaster, plants, and yeasts. Lectins that recognize more complex structures at the cell surface, such as C-type lectins and galectins, are also found in invertebrate organisms as...

Three lectins have been isolated from an extract of mistletoe (Viscum album) by affinity chromatography on partially hydrolysed Sepharose and human immunoglobulin- Sepharose. The lectins differ in molecular weight and sugar specificity (lectin I, mol.wt. 11500, D-galactose-specific; lectin II, mol.wt. 60000, both D-galactose- and N-acetyl-D-galactosamine-specific; lectin III, mol. wt. 50000, N-...

Objective: Potato (Solanum tuberosum) and garlic (Allium sativum) are an important ubiquitously consumed dietary components and known to contain lectins, with potent and diverse biological functions. Present study aims to evaluate the mitogenicity and immunomodulatory potential of these lectins on human and murine lymphocytes. Methods: The lectin activity of raw and heat processed extracts alon...

This review outlines the antimicrobial activity of secondary metabolites and lectins, compounds usually associated to defense mechanisms of plants. Secondary metabolites are separated into nitrogen compounds (alkaloids, non-protein amino acids, amines, alcamides, cyanogenic glycosides and glucosinolates) and nonnitrogen compounds (monoterpenes, diterpenes, triterpenes, tetraterpenes, sesquiterp...

Lectins are carbohydrate recognizing proteins originating from diverse origins in nature, including animals, plants, viruses, bacteria and fungus. Due to their exceptional glycan recognition property, they have found many applications in analytical chemistry, biotechnology and surface chemistry. This manuscript explores the current use of lectins for cancer diagnosis and therapy. Moreover, nove...

Lectins are proteins or glycoprotein’s of non-immune origin that exhibit specific binding affinity for the carbohydrate moiety of glycol-conjugates. Several plant lectins have been shown to induce cell death in cancer cells, suggesting that these molecules may have applications in cancer treatments. Cancer cells are known to express and/ or secrete glycol-conjugates with an aberrant glycan stru...

Lectins are carbohydrate-interacting proteins that play a pivotal role in multiple physiological and developmental aspects of all organisms. They can specifically interact with different bacterial and viral pathogens through carbohydrate-recognition domains (CRD). In addition, lectins are also of biotechnological interest because of their potential use as biosensors for capturing and identifyin...

To date, many efforts have been made to detect lectins in cells by using single imaging techniques. However, only a few dual-labeled glycan-based probes, which integrate advantageous features of two imaging methods to enhance the visualization of biological processes associated with lectins in cells, have been reported. Herein we describe the synthesis of dual fluorescence and magnetic resonanc...

Methyl 4-azidobenzoimidate, a photosensitive hetero-bifunctional cross-linking reagent, was synthesized and characterized. This reagent has an imidoester at one end, which reacts spontaneously with primary amines, and an arylazide at the other end, which reacts with a variety of chemical groups upon photolysis by ultraviolet radiation. The reagent molecules were attached to concanavalin A by re...
