Abstract
It has been clarified that pathogens bind to glycosphingolipid (GSL) receptors in mammals, but there have been very few reports on pathogen-binding GSLs in fish. Vibrios are facultative anaerobic bacteria ubiquitous in marine and brackish environments. They are members of the normal intestinal microflora of healthy fish, but some species can cause a disease called vibriosis in fish and shellfish when the hosts are physiologically or immunologically weakened. The adherence of vibrios to host intestinal tracts is a significant event not only for survival and growth but also in terms of pathogenicity. We show in this mini-review that sialic acid-containing GSLs (gangliosides), GM4 and GM3, are receptors to which vibrios adhere to epithelial cells in the intestinal tract of fish. We also describe the enzymes responsible for synthesizing these Vibrio-binding gangliosides in fish.
期刊介绍：
Glycoconjugate Journal publishes articles and reviews on all areas concerned with:
function, composition, structure, biosynthesis, degradation, interactions, recognition and chemo-enzymatic synthesis of glycoconjugates (glycoproteins, glycolipids, oligosaccharides, polysaccharides and proteoglycans), biochemistry, molecular biology, biotechnology, immunology and cell biology of glycoconjugates, aspects related to disease processes (immunological, inflammatory, arthritic infections, metabolic disorders, malignancy, neurological disorders), structural and functional glycomics, glycoimmunology, glycovaccines, organic synthesis of glycoconjugates and the development of methodologies if biologically relevant, glycosylation changes in disease if focused on either the discovery of a novel disease marker or the improved understanding of some basic pathological mechanism, articles on the effects of toxicological agents (alcohol, tobacco, narcotics, environmental agents) on glycosylation, and the use of glycotherapeutics.
Glycoconjugate Journal is the official journal of the International Glycoconjugate Organization, which is responsible for organizing the biennial International Symposia on Glycoconjugates.
