claimThe process of immunomodulation by polysaccharides involves direct interaction with TLR proteins and the regulation of downstream signaling cascades, encompassing both MyD88-dependent and independent pathways.
referenceShen et al. (2024) described the role of polysaccharides in immunity.
claimPolysaccharides from medicinal flora, pectin from citrus fruits, and inulin from chicory strengthen innate immune responses against pathogens while mitigating excessive inflammatory reactions.
claimPolysaccharides from medicinal flora, including β-glucans from Ganoderma lucidum and Lentinula edodes, Astragalus polysaccharides from Astragalus membranaceus, and arabinogalactan from larch trees, regulate Toll-like receptor (TLR) signaling pathways.
referencePolysaccharides from Arctium lappa L. (greater burdock) regulate immune responses and inhibit inflammation in cells via the TLR4/NF-κB signaling pathway, as reported by Zeng et al. in 2024.
claimCoriolus versicolor polysaccharides promote NK cell proliferation and interferon-γ synthesis.

claimXuancheng Baicao Plants Industry and Trade Ltd., located in China, commercially offers powdered Lonicera (honeysuckles) extract containing 25% chlorogenic acid and Ganoderma extract with a 30% polysaccharide content.
claimPolysaccharides and saponins from medicinal plants activate immune cells, such as macrophages and neutrophils, to phagocytize infections.
procedureBiofilm development occurs in stages: (i) free-living (planktonic) cells attach to a pre-conditioned surface via random propulsion, chemotaxis, or motion, which is initially reversible and influenced by physical and chemical variables; (ii) cells permanently attach using adhesion proteins like fimbriae, followed by the emergence of internal linkages and extracellular polymeric substances (EPS) composed of polysaccharides (e.g., colonic acid, chitosan, alginate), enzymes, RNA, DNA, nutrients, proteins, and surfactants; (iii) the biofilm community undergoes microbial proliferation and communication via chemical signaling, resulting in micro-colony growth.
referenceMa Y-L, Zhu D-Y, Thakur K, Wang C-H, Wang H, Ren Y-F, et al. published a 2018 study in the International Journal of Biological Macromolecules titled 'Antioxidant and antibacterial evaluation of polysaccharides sequentially extracted from onion (Allium cepa L.)', which evaluates the biological properties of onion-derived polysaccharides.

claimNatural fibers are composed of either polysaccharides, such as cellulose, hemicellulose, and lignin, or proteins, such as fibroin and collagen.
claimChitin is the second most abundant natural polysaccharide on earth and is found in sources including crab and shrimp shells, arthropod exoskeletons, molluscan squid shells, and mushrooms.
claimAlginate is a polysaccharide produced by bacteria and seaweed that varies in composition, modifications, molecular mass, viscoelasticity, and polydispersity depending on its source.
claimBiofibers are biopolymers composed of polysaccharides and proteins that can be extracted from biomass, synthesized using bio-derived monomers, or produced by microorganisms.
The role of light in regulating plant growth, development and sugar ... frontiersin.org Jan 6, 2025 3 facts
claimIn Anoectochilus roxburghii, blue light significantly increases fresh weight, dry weight, and chlorophyll a content, while yellow light significantly increases the content of soluble sugars and polysaccharides.
claimIn Dendrobium officinale, high light exposure causes stems to change from green to red due to the accumulation of red pigment in epidermal cells, and significantly increases anthocyanin levels and total polysaccharide content, a process regulated by the DoHY5 protein.
procedureDuring natural product biosynthesis in plants, UDP-monosaccharide and GDP-monosaccharide are formed in the cytoplasm, transported to the Golgi apparatus by nucleotide sugar transport proteins, and then transferred by glycosyltransferases (GTs) to extended chains to form polysaccharides via dehydration and condensation, before being transported to different parts of the plant body via secretory vacuoles.
