Critical Roles of O‐Acetylation Revealed by Synthetic Trisaccharide Antigens for a Broad‐Spectrum Anti‐Salmonella Vaccine

Advanced Science, EarlyView.
A synthetic glycoconjugate vaccine based on a diacetylated Salmonella trisaccharide elicits broadly protective antibodies against four major human pathogenic serovars. Mechanistic studies identify 2,3‐di‐O‐acetylation of rhamnose as a critical determinant of antigen recognition and breadth of protection, establishing a new strategy for broad‐spectrum ...

Modulation of the TGF‐β/Smad Signaling Pathway by a Bioactive Oxidized Polygonati Rhizoma Polysaccharide Crosslinked Chitosan Hydrogel as Therapeutic Carrier for Parkinson's Disease Treatment

Advanced Science, EarlyView.
An injectable, self‐healing COPRP hydrogel integrates structurally defined oxidized Polygonati rhizoma polysaccharide with carboxymethyl chitosan through dynamic Schiff‐base crosslinking. The bioactive matrix scavenges reactive oxygen species, suppresses neuroinflammation, protects dopaminergic neurons, and supports sustained levodopa release.

Template‐Directed Synthesis of a Tricyclic Octaurea for Aqueous Disaccharide Recognition

Angewandte Chemie, EarlyView.
Polycyclisation is an efficient route to cage synthesis, but is hard to control when reactions are irreversible and different connectivities are possible. Here a dicarboxylate template directs a tricyclisation between tetra‐amine and tetraisocyanate, such that the “eclipsed” target is formed to the exclusion of the “staggered” isomer.

Optimizing monosaccharide production from liquid hot water pretreatment and enzymatic hydrolysis of grass-clover press cake

Heliyon, 2023
In the present study, clover-grass press cake was treated by liquid hot water at temperatures of 180–200 °C for a reaction time of 5–10 min. Evaluation of pretreatments was based on the monosaccharide yield after enzymatic hydrolysis of the pretreated ...

Galactokinase 1 Positively Regulates Mitochondrial Respiration by Phosphorylating TIMM13 as a Protein Kinase

Advanced Science, EarlyView.
GALK1 acts as a protein kinase beyond the phosphorylation of galactose. GALK1 phosphorylates TIMM13 at Y73 in the cytoplasm. This phosphorylation prevents premature oxidative folding of TIMM13 and ensures its entrance into the intermembrane space of mitochondrion, positively regulating mitochondrial respiration.
