Expression of sialic acids and other nonulosonic acids in Leptospira [PDF]

, 2012
BackgroundSialic acids are negatively charged nine carbon backbone sugars expressed on mammalian cell surfaces. Sialic acids are part of a larger family of nonulosonic acid (NulO) molecules that includes pseudaminic and legionaminic acids.

Possible Influences of Endogenous and Exogenous Ligands on the Evolution of Human Siglecs

Frontiers in Immunology, 2018
Sialic acids, a group of acidic sugars abundantly expressed in the tissues of deuterostome animals but rarely found in microbes, serve as a “signature of self” for these animals. Cognate sensors for sialic acids include Siglecs, a family of transmembrane

Substrate-bound outward-open structure of a Na+-coupled sialic acid symporter reveals a new Na+ site [PDF]

, 2018
Many pathogenic bacteria utilise sialic acids as an energy source or use them as an external coating to evade immune detection. As such, bacteria that colonise sialylated environments deploy specific transporters to mediate import of scavenged sialic ...

Histochemical properties of sialic acids and antimicrobial substances in canine anal glands

European Journal of Histochemistry, 2011
The functional properties of sialic acids appear to be manifold. Additionally, antimicrobial substances serve as a non-specific defense against microorganisms. In this study, therefore, the localization of sialic acids and antimicrobial substances in the

Presence of N-acetylneuraminic acid in the lung during postnatal development

European Journal of Histochemistry, 2020
Sialic acids, particularly N-acetylneuraminic acid (Neu5Ac), are present as terminal components of rich and complex oligosaccharide chains, which are termed glycans, and are exhibited on the cell surfaces, especially on epithelial cells.

Sialic acid utilization by Cronobacter sakazakii [PDF]

, 2013
Background: The Cronobacter genus is composed of seven species, and can cause infections in all age groups. Of particular concern is C. sakazakii, as this species is strongly associated with severe and often fatal cases of necrotizing enterocolitis and ...

One-way trip: Influenza virus' adaptation to gallinaceous poultry may limit its pandemic potential [PDF]

, 2014
We hypothesise that some influenza virus adaptations to poultry may explain why the barrier for human-to-human transmission is not easily overcome once the virus has crossed from wild birds to chickens.

Changes in the Serum and Tissue Levels of Free and Conjugated Sialic Acids, Neu5Ac, Neu5Gc, and KDN in Mice after the Oral Administration of Edible Bird’s Nests: An LC–MS/MS Quantitative Analysis

Separations
Edible bird’s nests have a variety of biological activities, the main components of which are sialic acids. Sialic acids are a group of nine-carbon N-acetylated derivatives of neuraminic acid containing a keto group at position C2 and play important ...

Effects of histamine and sodium hypochlorite on prooxidand state in the rats erytrocytes

Current Issues in Pharmacy and Medical Sciences, 2020
We studied the simultaneous influence of histamine and sodium hypochlorite (SH) on lipid peroxidation processes, as well as the level of structural changes in membranes (via the content of sialic acid) in rat erythrocytes.
