Cryptococcus neoformans, a facultative intracellular pathogen of macrophages, is unique among medically important fungi in its possession of a polysaccharide capsule. Capsule represents the organism's major virulence factor. In the absence of opsonins, binding of encapsulated C. neoformans to macrophages is minimal. Following incubation in serum, C. neoformans potently activates complement, res...
A polyethylenimine adjuvant modified by mannose, which may be used in the study of vaccine adjuvant, was prepared this paper. Its structure characterized infrared spectroscopy and its micromorphology observed transmission electron microscopy. series mannose-modified polyvinylimine were according to molar ratio primary amine groups between mannose polyvinylimine, their storage stability at 4°C. ...
Introduction: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder in children that may lead to anxiety, frequent physician visits and school absenteeism. The aim of this study is to reviewe effects of probiotic for irritable bowel syndrome. Materials and Methods: This study review articles about probiotic for irritable bowel syndrome in pubmed and google scholar. Results: M...
Interactions between cells or between cell and substratum involve specific receptors and their ligands. Among the various cell surface receptors identified during the last decades, the carbohydrate-binding proteins, e.g., lectins are of peculiar interest because glycolipids, glycoproteins and proteoglycans have been shown to interact with lectins on the surface of animal cells. Animal lectins a...
The methylotrophic yeast, Pichiapastoris, is an important organism used for the production of therapeutic proteins. However, the presence of fungal-like glycans, either N-linked or O-linked, can elicit an immune response or enable the expressed protein to bind to mannose receptors, thus reducing their efficacy. Previously we have reported the elimination of β-linked glycans in this organism. In...
Phagocytosis of three types of fluorescein-labeled test particles by rat alveolar macrophages (AM) were studied: spherical silica (3.2 microm), heat-killed Candida albicans (3.8 microm), and heat-killed Cryptococcus neoformans (6.1 microm) opsonized with specific IgG. These particles should attach to scavenger, mannose, and Fc receptors, respectively. Both control AM and AM pretreated for 20 h ...
A specific phospholipase A(2) receptor from porcine cerebral cortex has been characterized (K(d) = 145 nM, B(max) = 0.4 pmol/mg membrane protein) by using a radioiodinated derivative of ammodytoxin C (AtxC), a snake venom presynaptically neurotoxic group IIA phospholipase A(2). After the receptor was solubilized in a ligand-binding form, it was approximately 14,000-fold enriched by chromatograp...
