These viruses include important human and animal pathogens, such as influenza, parainfluenza, mumps, corona, noro, rota, and DNA tumor viruses. Sialic acid is synthesized by glucosamine 6 phosphate and acetyl-CoA through a transferase, resulting in N -acetylglucosamine-6-P. This becomes N -acetylmannosamine-6-P through epimerization, which reacts with phosphoenolpyruvate producing N -acetylneuraminic-9-P (sialic acid). α2,6-linked sialic acid serves as a high-affinity receptor for cancer oncolytic virotherapy with Newcastle disease virus. Li Q (1), Wei D (1), Feng F (1), Wang XL (1), Li C (1), Chen ZN (2), Bian H (3). Siglecs are sialic acid‐recognizing receptors of the immunoglobulin (Ig) superfamily expressed on immune cells.

Sialic acid recognition remains an interesting and challenging target in molecular receptor design. Herein, we report a series of benzoboroxole-based receptors in which cationic hydrogen-bond donors have been introduced and shown to promote multipoint sialic acid recognition. One striking feature revealed by these receptors is that the carboxylate sialic acid residue is the primary binding

We demonstrate that removal of cell surface sialic acid inhibits HAdV-D26 infection, and provide a high-resolution crystal structure of HAdV-D26 fiber-knob in complex with sialic acid. 2020-07-08 · Since sialic acid alone cannot fulfill a signaling function, the virus needs to activate downstream factors to trigger endocytic uptake. Recently, the epidermal growth factor receptor (EGFR), a member of the receptor-tyrosine kinase family, was shown to be activated by IAV and transmit cell entry signals.

2009-05-05 · Hello Professor, Thank you for your blog. I have one question about the sialic acid receptors. My understanding is that the avian influenza virus has a preferential binding to alpha(2,3) linked sialic acids, but when it becomes pandemic, in order to transmit from human to human, it can also bind to alpha(2,6) linked sialic acids. Sialic acid recognition remains an interesting and challenging target in molecular receptor design.

By a series of amino acid changes on the HA surface protein, AIVs can switch receptor specificity and recognize α2,6 SA positive cells, including human respiratory epithelial cells. 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).

As for Ad37, the receptor used by CVA24v on corneal cells also appears to be one or more sialic acid-containing glycoproteins. Sialic Acid Receptors of Emerging and Zoonotic Viruses Many viruses across virus families often target particular classes of receptors, such as sialylated glycans, cell adhesion molecules, to mediate cellular entry. 2019-09-14 · Sialic acid-binding immunoglobulin-like lectin (Siglecs), the receptor of Sia, has been well studied recently . The Sia-Siglec axis of some immune cells including dendritic cells (DCs), treg cells, B lymphocytes and monocytes is closely related to the inflammation in atherosclerosis [ 13 , 14 , 15 ].

The interaction between influenza virus hemagglutinin and its cell-surface receptor, 5-N-acetylneuraminic acid (sialic acid), was probed by the synthesis of 12 sialic acid analogs, including derivatives at the 2-carboxylate, 5-acetamido, 4-, 7-, and 9-hydroxyl, and glycosidic positions.

Sialic acids are related to several different diseases observed in humans. Salla disease.

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. It is commonly accepted that avian influenza viruses (AIVs) bind to terminal a2,3 sialic acid (SA) residues whereas human influenza Jan 1, 2001 Most such receptors are expressed on other leukocytes, with only a as a nonphagocytic, sialic acid–dependent sheep erythrocyte receptor.2 Jun 15, 2014 There are receptor families that specifically recognize sialoglycans such as selectins or sialic acid-binding immunoglobulin-like lectins (Siglecs) The siglecs are a family of fourteen sialic acid binding proteins that function as cell signaling co-receptors and are primarily expressed on various leukocytes that Jul 8, 2020 Sialylated glycans serve as IAV attachment factors but are not able to transmit signals across the plasma membrane.
