Cystic hydatid disease is caused by cystic larval (metacestode) stages of Echinococcus granulosus. This parasite can potentially occur all over the world especially in Mediterranean and Middle East countries and some parts of Africa, Latin America and China which have major foci of human infections. The cyst wall of metacestodes consists of inner, middle and external layers. To date, little att...

The microvascular endothelium of the kidney glomerulus is injured in Shiga-like toxigenic bacterial infection, genetic or acquired loss of complement regulatory protein function, and allo-immune responses of solid-organ or bone marrow transplantation. Existing models of diseases with glomerular endothelial cell (EC) injury, collectively grouped as thrombotic microangiopathies, are problematic, ...

In order to improve the absorption of nanoparticles in the brain following nasal administration, a novel protocol to conjugate biorecognitive ligands-lectins to the surface of poly (ethylene glycol)-poly (lactic acid) (PEG-PLA) nanoparticles was established in the study. Wheat germ agglutinin (WGA), specifically binding to N-acetyl-D-glucosamine and sialic acid, both of which were abundantly ob...

We describe studies of a new model cell adhesion system involving liposomes bearing lectins and the glycosphingolipid, asialomonosialoganglioside (asialoGM1). The model provides a simple analysis of experimental data to elucidate the mechanism of heterophilic cell-cell adhesion mediated by multiple protein-carbohydrate interactions. Phospholipid vesicles bearing the fatty acid conjugate of a gl...

This article reviews lectins of animal and plant origin that induce apoptosis and autophagy of cancer cells and hence possess the potential of being developed into anticancer drugs. Apoptosis-inducing lectins encompass galectins, C-type lectins, annexins, Haliotis discus discus lectin, Polygonatum odoratum lectin, mistletoe lectin, and concanavalin A, fucose-binding Dicentrarchus labrax lectin,...

manufacturing new hepatitis b virus vaccines, specifically by the use of nanoparticles, is of high global interest. in this paper, a new biocompatible and biodegradable structure of nano-sized hepatitis b virus’ surface antigen (hbsag) was generated by conjugation with dendrimers, a low cost biodegradable and biocompatible polymer. the physicochemical properties of the conjugate were characteri...

The endocytosis of ricin, horseradish peroxidase (HRP), and a conjugate of ricin-HRP by monolayer cultures of murine neuroblastoma was studied using morphological and biochemical techniques. The binding of (125)I-ricin and (125)I-ricin-HRP to cells at 4 degrees C, as a function of ligand concentration, was a saturable process. The apparent affinity constants, determined at equilibrium, were 2.8...

mannose-binding lectin (mbl) is a protein of innate immune system that is involved in opsonization and complement activation. mbl deficiency is associated with predisposition to infectious diseases; however subnormal levels are also seen in healthy subjects. the aim of this study was to investigate the prevalence and clinical manifestation of mbl deficiency in patients with increased susceptibi...

Carbohydrates have been suggested to account for some IgE cross-reactions between various plant, insect, and mollusk extracts, while some IgG antibodies have been successfully raised against plant glycoproteins. A rat monoclonal antibody raised against elderberry abscission tissue (YZ1/2.23) and rabbit polyclonal antiserum against horseradish peroxidase were screened for reactivity in enzyme-li...
