Recognition of specific sialoglycan structures by oral streptococci impacts the severity of endocardial infection. [PDF]

open access: yes, 2019
Streptococcus gordonii and Streptococcus sanguinis are primary colonizers of the tooth surface. Although generally non-pathogenic in the oral environment, they are a frequent cause of infective endocarditis.

Siglecs facilitate HIV-1 infection of macrophages through adhesion with viral sialic acids. [PDF]

open access: yesPLoS ONE, 2011
Human immunodeficiency virus type 1 (HIV-1) infects macrophages effectively, despite relatively low levels of cell surface-expressed CD4. Although HIV-1 infections are defined by viral tropisms according to chemokine receptor usage (R5 and X4 ...

Sialic acid acquisition in bacteria - one substrate many transporters [PDF]

open access: yes, 2016
The sialic acids are a family of 9-carbon sugar acids found predominantly on the cell-surface glycans of humans and other animals within the Deuterostomes and are also used in the biology of a wide range of bacteria that often live in association with ...

Sialic acid utilization by Cronobacter sakazakii [PDF]

open access: yes, 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 ...

Ferrets exclusively synthesize Neu5Ac and express naturally humanized influenza A virus receptors [PDF]

open access: yes, 2014
Mammals express the sialic acids ​N-acetylneuraminic acid (​Neu5Ac) and ​N-glycolylneuraminic acid (​Neu5Gc) on cell surfaces, where they act as receptors for pathogens, including influenza A virus (IAV). ​Neu5Gc is synthesized from ​Neu5Ac by the enzyme

Mice lacking sialyltransferase ST3Gal-II develop late-onset obesity and insulin resistance [PDF]

open access: yes, 2016
Sialyltransferases are a family of 20 gene products in mice and humans that transfer sialic acid from its activated precursor, CMP-sialic acid, to the terminus of glycoprotein and glycolipid acceptors.

Glycosidation of sialic acid.

open access: yesJournal of Synthetic Organic Chemistry, Japan, 1989
N-Acetylneuraminic acid (Neu5Ac), a typical sialic acid, located at the non-reducing ends of carbohydrate chains of glycoproteins and glycolipids plays an important role in biological phenomena. The synthesis of oligosaccharides which contain Neu5Ac has focused with clarification of their vital functions.

Prediction of specific virus outbreaks made from the increased concentration of a new class of virus genomic peptides, replikins. [PDF]

open access: yes, 2011
Advance warning of pathogen outbreaks has not been possible heretofore. A new class of genomic peptides associated with rapid replication was discovered and named replikins. Software was designed to analyze replikins quantitatively.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

open access: yesHepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.
