Role of sialic acid in brachyspira hyodysenteriae adhesion to pig colonic mucins [PDF]

open access: yes, 2019
Infection with Brachyspira hyodysenteriae results in mucoid hemorrhagic diarrhea. This pathogen is associated with the colonic mucus layer, mainly composed of mucins. Infection regulates mucin O-glycosylation in the colon and increases mucin secretion as

Sialic acid O-acetylation patterns and glycosidic linkage type determination by ion mobility-mass spectrometry

open access: yesNature Communications, 2023
O-acetylation is a common modification of sialic acids that has been implicated in a multitude of biological and disease processes. A lack of analytical methods that can determine exact structures of sialic acid variants is a hurdle to determine roles of

Cellular and Molecular Engineering of Glycan Sialylation in Heterologous Systems

open access: yesMolecules, 2021
Glycans have been shown to play a key role in many biological processes, such as signal transduction, immunogenicity, and disease progression. Among the various glycosylation modifications found on cell surfaces and in biomolecules, sialylation is ...

Unraveling the Differences of the Hydrolytic Activity of Trypanosoma cruzi trans-Sialidase and Trypanosoma rangeli Sialidase: A Quantum Mechanics–Molecular Mechanics Modeling Study [PDF]

open access: yes, 2014
Chagas’ disease, also known as American trypanosomiasis, is a lethal, chronic disease that currently affects more than 10 million people in Central and South America. The trans-sialidase from Trypanosoma cruzi (T. cruzi, TcTS) is a crucial enzyme for the

Sialic Acid Mimetics to Target the Sialic Acid–Siglec Axis

open access: yesTrends in Biochemical Sciences, 2016
Sialic acid sugars are vital regulators of the immune system through binding to immunosuppressive sialic acid-binding immunoglobulin-like lectin (Siglec) receptors on immune cells. Aberrant sialic acid-Siglec interactions are associated with an increasing number of pathologies including infection, autoimmunity, and cancer.

Enzymatic Synthesis of Trideuterated Sialosides

open access: yesMolecules, 2019
Sialic acids are a family of acidic monosaccharides often found on the termini of cell surface proteins or lipid glycoconjugates of higher animals. Herein we describe the enzymatic synthesis of the two isotopically labeled sialic acid derivatives d3-X ...

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.

Histochemical localization of sialic acids and antimicrobial substances in eccrine glands of porcine snout skin

open access: yesEuropean Journal of Histochemistry, 2012
The distribution of sialic acids and antimicrobial products (lysozyme, IgA, lactoferrin, β-defensin 2) as well as Rab3D in the eccrine glands of porcine snout skin was studied by sialoglycoconjugate histochemistry and immunohistochemistry.

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 ...

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.
