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 2017-04-06 · IAVs bind to sialic acid (SA) receptors on host cells, and it is widely believed that hosts expressing both SA α2,3-Gal and SA α2,6-Gal receptors could facilitate genetic reassortment of avian 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. 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 ].

Crys-tal structures of the MuV attachment protein hemagglutinin-neur-aminidase (MuV-HN) alone and in complex with the α2,3-sialylated trisaccharide revealed that in addi tion to the interaction between the MuV-HN active site residues and sial ic acid, other residues, including Sialic acid receptors: focus on their role in influenza infection Guadalupe Ayora-Talavera Virology Laboratory, Center of Regional Research Dr Hideyo Noguchi, Autonomous University of Yucatan, Merida, Yucatan, Mexico Abstract: Receptor-binding specificity is a major determinant of host range, pathogenesis, and interspecies transmission in influenza virus. Among coronaviruses, several members are able to interact with sialic acids. For bovine coronavirus (BCoV) and related viruses, binding to cell surface components containing N-acetyl-9- O-acetylneuraminic acid is essential for initiation of an infection. These viruses resemble influenza C viruses because they share not only the receptor determinant, but also the presence of an acetylesterase 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.

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.

Wan H(1), Perez DR. Author information: (1)Department of Veterinary Medicine, University of Maryland, College Park, MD 20742-3711, USA. Siglecs are Type I transmembrane proteins where the NH 3 +-terminus is in the extracellular space and the COO −-terminus is cytosolic. Each Siglec contains an N-terminal V-type immunoglobulin domain (Ig domain) which acts as the binding receptor for sialic acid. Human coronaviruses OC43 and HKU1 are related, yet distinct respiratory pathogens, associated with common colds, but also with severe disease in the frail. Both viruses employ sialoglycan-based receptors with 9- O -acetylated sialic acid (9- O -Ac-Sia) as key component.
