Polysaccharide Adjuvants as Innate Immune Trainers: Bridging Pattern Recognition Receptor (PRR) Activation and Metabolic Reprogramming for Synthetic Vaccine Design

Advanced Science, Volume 12, Issue 48, December 29, 2025.
Polysaccharides modulate immune responses by engaging pattern recognition receptors (PRRs) to induce T‐cell activation. In vaccine design, their particle size critically influences lymph node targeting and activation mechanisms. By engineering structural complexity and multivalent PRR engagement, polysaccharides enable precise modulation of immune ...

Structure and anticoagulant activity of sulfated galactans. Isolation of a unique sulfated galactan from the red algae Botryocladia occidentalis and comparison of its anticoagulant action with that of sulfated galactans from invertebrates.

The Journal of biological chemistry, 2000
We have characterized the structure of a sulfated d-galactan from the red algae Botryocladia occidentalis. The following repeating structure (-4-alpha-d-Galp-1-->3-beta-d-Galp-1-->) was found for this polysaccharide, but with a variable sulfation pattern.

Medicine‐Food Plant Polysaccharides Modulate Diabetes and Diabetic Complications Through Maintaining Gut Function: A Review

Food Frontiers, Volume 6, Issue 6, Page 2720-2765, November 2025.
Polysaccharides derived from medicine‐food plants restore intestinal barrier integrity and microbiota balance while modulating short‐chain fatty acid levels. These modifications significantly alleviate diabetes and its complications, including nephropathy, retinopathy, cardiovascular disease, and neuropathy.

Characterization of the thermophilic xylanase Fsa02490Xyn from the hyperthermophile Fervidibacter sacchari belonging to glycoside hydrolase family 10

FEBS Open Bio, Volume 15, Issue 10, Page 1629-1642, October 2025.
Fervidibacter sacchari is a member of the bacterial phylum Armatimonadota, only a few of which have been cultivated. It is a hyperthermophilic polysaccharide degradation specialist. We show that a secreted enzyme, Fsa02490Xyn, is an endoxylanase belonging to glycoside hydrolase family 10.

Molecular Evolution and Gene Diversity of Dermatan Sulfate Sulfotransferases in Ascidians

Proteoglycan Research, Volume 3, Issue 4, October 2025.
ABSTRACT Ascidians (Chordata, Tunicata) are model organisms for studying molecules, particularly sulfated glycosaminoglycans (GAGs), due to their phylogenetic proximity to vertebrates and unique GAG variants. Over‐sulfated dermatan sulfate (DS) contributes to proteoglycan diversity and cellular processes in metazoans.

Characterization of two immunomodulating homogalacturonan pectins from green tea [PDF]

, 2014
Two natural homogalacturonan (HG) pectins (MW ca. 20 kDa) were isolated from green tea based on their immunomodulatory activity. The crude tea polysaccharides (TPS1 and TPS2) were obtained from green tea leaves by hot water extraction and followed by 40%

Sustainable production of exopolysaccharides from quinoa stalk hydrolysates using halotolerant Bacillus swezeyi: fermentation kinetics and product characterization

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 5, Page 1326-1348, September/October 2025.
Abstract Microbial exopolysaccharides (EPSs) have attracted increasing attention due to their versatile applications across diverse areas. However, large‐scale production of EPSs remains challenging due to the high production costs, primarily driven by the use of synthetic carbon sources.

Rising from the Sea: Correlations between Sulfated Polysaccharides and Salinity in Plants [PDF]

, 2011
High salinity soils inhibit crop production worldwide and represent a serious agricultural problem. To meet our ever-increasing demand for food, it is essential to understand and engineer salt-resistant crops.

Structural heterogeneity among unique sulfated L-galactans from different species of ascidians (tunicates)

Journal of Biological Chemistry, 1989
The sulfated polysaccharides that occur in the tunic of ascidians differ markedly in molecular weight and chemical composition. A high molecular weight fraction (F-1), which has a high galactose content and a strong negative optical rotation, is present in all species.
