2006-03-15 · Quail carry sialic acid receptors compatible with binding of avian and human influenza viruses. Wan H(1), Perez DR. Author information: (1)Department of Veterinary Medicine, University of Maryland, College Park, MD 20742-3711, USA.

Using a lectin-based staining based on specific agglutinins, we found that, in addition to the presence of sialic acid alpha2,3-galactose (SAalpha2,3-gal) linked receptors, there are abundant sialic acid alpha2,6-galactose (SAalpha2,6-gal) linked receptors in quail trachea and intestine. “essential arginine” critical for sialic acid recognition in both Siglec-14 and Siglec-5 is present in humans but mutated in almost all great ape alleles.—Angata, T., Hayakawa, T., Yamanaka, M., Varki, A., Nakamura, M. Discovery of Siglec-14, a novel sialic acid receptor undergoing concerted evolution with Siglec-5 in pri-mates. These viruses resemble influenza C viruses because they share not only the receptor determinant, but also the presence of an acetylesterase that releases the 9- O -acetyl group from sialic acid and thus abolishes the ability of the respective sialoglycoconjugate to function as a receptor for BCoV. The virus binds to the dipeptidyl peptidase 4 (DPP4) entry receptor on respiratory epithelial cells via its spike protein. We here report that the MERS-CoV spike protein selectively binds to sialic acid (Sia) and demonstrate that cell-surface sialoglycoconjugates can serve as an attachment factor. exhibit preferential binding to α2,6- and α2,3-linked sialic acids, respectively (11).

2019-06-03 · The receptor therefore docks into a distinct groove from those used by either human galectin-3 (ref. 52) or the rhesus rotavirus sialic acid-attachment protein 53 (VP8*) to recognize their The “essential arginine” critical for sialic acid recognition in both Siglec‐14 and Siglec‐5 is present in humans but mutated in almost all great ape alleles.—Angata, T., Hayakawa, T., Yamanaka, M., Varki, A., Nakamura, M. Discovery of Siglec‐14, a novel sialic acid receptor undergoing concerted evolution with Siglec‐5 in primates. Diseases. Sialic acids are related to several different diseases observed in humans. Salla disease. Salla disease is an extremely rare illness which is considered the mildest form of the free sialic acid accumulation disorders though its childhood form is considered an aggressive variant and people who suffer from it have mental retardation.

We showed that this ocular virus, like Ad37, is also able to use SA as a receptor on corneal cells but not on conjunctival cells. This suggested that CVA24v may use two different receptors. As for Ad37, the receptor used by CVA24v on corneal cells also appears to be one or more sialic acid-containing glycoproteins.

In the other LDL receptor-related protein-1 is a sialic-acid-independent receptor for myelin- associated glycoprotein that functions in neurite outgrowth inhibition by MAG and Dec 9, 2010 Abstract.

Maturation of the notch receptor involves cleavage at the prospective by a galactosyltransferase , and the addition of a sialic acid by a sialyltransferase. To add

In sialic acid (2), both the glycerol chain and the α- earlier studies have shown that they have receptors for both avian (sialic acid-alpha-2,3-terminal saccharides (SA- alpha-2,3)) and swine/human (SA-alpha-2,6) influenza viruses in the upper the cellular receptor in order to inhibit adenoviral attachment to and infection of human corneal epithelial (HCE) cells. Synthetic routes to three different classes of sialic acid conjugates, i.e. derivatives of sialic acid, 3’-sialyllactose and N-acyl modified sialic acids, and their multivalent counterparts on … Siglecs (sialic acid Ig-like lectins) are transmembrane, sialic acid (Neu5Ac)-binding lectins that are expressed in a variety of cell types, including immune cells, nerve tissue, and others, but are mainly found on cells of the hematopoietic system. 11 All siglecs have 2–17 extracellular Ig-like domains, with the most distal N-terminal domain being the one responsible for the binding of Sialic acid synthesis in animals takes place primarily in the cytosol and involves four enzymes participating in a five-step process (see Figure 3).The dual activity enzyme UDP-GlcNAc 2-epimerase/ ManNAc-6-kinase (gene symbol GNE) converts the starting substrate uridine 5'-diphosphate-N-acetyl-D-glucosamine (UDPGlcNAc) to N-acetyl-D-mannosamine (ManNAc) with removal of the UDP moiety and Sialic acid linked to glycoproteins and gangliosides is used by many viruses as a receptor for cell entry. These viruses include important human and animal pathogens, such as influenza, parainfluenza, mumps, corona, noro, rota, and DNA tumor viruses. Infections are initiated by the transmembrane spike (S) glycoprotein, which binds to host receptors and fuses the viral and cellular membranes. To understand the molecular basis of coronavirus attachment to oligosaccharide receptors, we determined cryo-EM structures of coronavirus OC43 S glycoprotein trimer in isolation and in complex with a 9-O-acetylated sialic acid.

Receptor tyrosine kinases Structural basis for human coronavirus attachment to sialic acid receptors The receptor-interacting site is conserved in all coronavirus S glycoproteins that Avian influenza and sialic acid receptors: more than meets the eye? bonds as a cellular receptor, we propose that the presence of this receptor in the eye also Avian influenza A viruses exhibit a strong preference for using alpha2,3-linked sialic acid as a receptor. Until recently, the presumed lack of this receptor in av S Crunkhorn · 2011 — They found that the two sialic acids of the GD1a glycan docked with two out of three previously described Ad37 sialic acid binding sites and Avian influenza H5 hemagglutinin binds with high avidity to sialic acid on of the influenza hemagglutinin receptor Sia alpha 2-3Gal on different O-glycan Sialic acid är en typisk monosackarid-enhet finns i Glykokonjugat. är sialic acid involverad i en mängd olika receptor-ligand interaktioner.

Animal species, like pigs and Japanese quail 2010-01-27 · Avian viruses preferentially bind to sialic acid α2,3-galactose (SAα2,3-Gal) linked receptors, whereas human strains bind to sialic acid α2,6-galactose (SAα2,6-Gal) linked receptors. To date, there has been no detailed account published on the distribution of SA receptors in the pig, a model host that is susceptible to avian and human influenza subtypes, thus with potential for virus Sialoadhesin (Sn) is one such receptor. It was originally characterized in the mouse on isolated resident bone marrow macrophages as a nonphagocytic, sialic acid–dependent sheep erythrocyte receptor.2 In situ, these macrophages bind avidly to developing myeloid and erythroid cells and are therefore well positioned to dispose of apoptotic cells and extruded erythroblast nuclei that are 2011-09-08 · Pigs are considered susceptible to influenza A virus infections from different host origins because earlier studies have shown that they have receptors for both avian (sialic acid-alpha-2,3-terminal saccharides (SA-alpha-2,3)) and swine/human (SA-alpha-2,6) influenza viruses in the upper respiratory tract. The sialic acid dependence of MAG inhibition was challenged by the recent identification of the Nogo-66 receptor (NgR1) as a high-affinity MAG receptor that supports binding in a sialic acid-independent manner (Domeniconi et al., 2002; Liu et al., 2002).
