Sialic acid on avian erythrocytes

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2019
Understanding variation in physiological traits across taxa is a central question in evolutionary biology that has wide-ranging implications in biomedicine, disease ecology, and environmental protection. Sialic acid (Sia), and in particular, 5-N-acetylneuraminic acid (Neu5Ac), is chemically bound to galactose and the underlying glycan via α2-3 or α2-6 ...

DNase I‐Mediated Chemotactic Nanoparticles for NETs Targeting and Microenvironment Remodeling Treatment of Acute Ischemic Stroke

Advanced Science, EarlyView.
The neutrophil extracellular traps (NETs) play an important role in reperfusion injury in ischemic stroke. Here, considering the unique vascular localization of NETs, a DNase I‐mediated NETs‐targeting nanoparticle is developed to integrate the catalytic and chemotactic functions of DNase I and achieve the synergistic regulation of the internal and ...

Akkermansia muciniphila‐Derived N‐Acetylspermidine Modulates the Localization of Intestinal α1,2‐Fucosylated Proteins to Maintain Gut Homeostasis

Advanced Science, EarlyView.
This study demonstrates that Akkermansia muciniphila alleviates colitis by enhancing intestinal α1,2‐fucosylation through its metabolite N‐acetylspermidine. Mechanistically, N‐acetylspermidine‐induced PIM1 inhibition promotes HDAC2‐mediated reduction of chromatin accessibility at TP73, thereby upregulating C1GALT1C1 to boost α1,2‐fucosylation.

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

Functions and Biosynthesis of O-Acetylated Sialic Acids

Topics in current chemistry, 2012
Sialic acids have a pivotal functional impact in many biological interactions such as virus attachment, cellular adhesion, regulation of proliferation, and apoptosis. A common modification of sialic acids is O-acetylation. O-Acetylated sialic acids occur

PLAUR+ Neutrophils Drive Anti‐PD‐1 Therapy Resistance in Patients with Hepatocellular Carcinoma by Shaping an Immunosuppressive Microenvironment

Advanced Science, EarlyView.
The present study reveals that PLAUR+ neutrophils are enriched in immunotherapy non‐responders and correlate with poor prognosis. PLAUR+ neutrophils dictate immunotherapy resistance in hepatocellular carcinoma by forming an immunosuppressive tumor microenvironment characterized by CD8+ T cell exclusion and macrophage‐dependent immune suppression.

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.
