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
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 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. And sialic acid-modified structures form the key fundamental determinants for a number of receptors with known involvement in cellular adhesiveness and cell trafficking, such as the Selectins and the Siglec families of carbohydrate recognizing receptors.On dendritic cells (DC), sialic acid-modified structures are involved in all their functions and their expression changes along CD22, a negative regulator of B cell antigen receptor signaling, binds glycoconjugates terminating in α2, 6 sialic acid. The physiological ligand(s) for CD22 remain unknown. We asked whether the sialic acid binding domains are necessary for CD22 to function as a negative regulator. Instead, we have identified sialic acid as a third adenovirus receptor moiety. First, Ad37 attachment to both CAR-expressing CHO cells and MHC-I alpha2-expressing Daudi cells was sensitive to neuraminidase treatment, which eliminates sialic acid on the cell surface.
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. Role of sialic acid in the macrophage glycolipid receptor for MIF. Liu DY, Petschek KD, Remold HG, David JR. Acidic glycolipids from guinea pig macrophages enhance the response of macrophages to migration inhibitory factor (MIF), suggesting a role of glycolipid receptors for this lymphocyte mediator.

derivatives of sialic acid, 3’-sialyllactose and N-acyl modified sialic acids, and their multivalent counterparts on human serum albumine 2021-01-01 · Taken together, sialic-acid-based receptor analogues might hold promise as entry inhibitors for sialic-acid-dependent viruses, especially for influenza. The possibility of using monosaccharides (such as Neu5Ac) could pave the way for broad-spectrum antiviral drugs with a virucidal mechanism of action.

Moreover, surface-exposed sialic acid increases the affinity of the soluble main receptor involved in phagocytosis is CR3, which binds iC3b.
Recognition of | Find, read and cite all the research Sialic Acid-Containing Glycans as Cellular Receptors for Ocular Human Adenoviruses: Implications for Tropism and Treatment Chandra, Naresh Umeå University, Faculty of Medicine, Department of Clinical Microbiology, Section of Virology. A new SELEX scheme is proposed for the selection of aptamers targeting a specific epitope of a native protein. Anti-sialic acid receptor (SAR) aptamers that inhibit H1 hemagglutination at a low picomole dose are selected accordingly. 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.
