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

open access: yesAdvanced 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

open access: yesAdvanced 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.

High‐Density Type I Collagen Promotes IFN‐γ+ CD8+ T Cell Exhaustion via SAT1‐ASS1‐Mediated Glutamine Accumulation and Ferroptosis in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
High‐density type I collagen promotes glutamine (Gln) accumulation–related ferroptosis of TNBC cells via the spermidine/spermine N1‐acetyltransferase 1 (SAT1)‐ argininosuccinate synthase (ASS1) signaling pathway, thus depriving immune cells of Gln supply and inducing IFN‐γ+ CD8+ T cell exhaustion in the TME.

Integration of the D‐Genome Reshapes Gene Transcription, Chromatin Architecture, and Metabolome of Allohexaploid Wheat, Leading to Enhanced Environmental Adaptability

open access: yesAdvanced Science, EarlyView.
Integration of the D‐genome reshapes gene transcription, chromatin architecture, and the metabolome of hexaploid wheat, leading to enhanced adaptability to salt, UV‐B, and alkali stress. ABSTRACT The hybridization‐led integration of the D‐genome into domesticated tetraploid wheat gave rise to allohexaploid wheat, the most cultivated wheat globally ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.
