PAP80-2a, purified from Pholiota adiposa mycelia, is a polysaccharide exhibiting prominent antitumor effects. However, the yield of PAP80-2a was low and its structure has not been characterized, ...

In Gram-negative bacteria, which include some of the most devastating human pathogens, just two mechanisms for the export of polysaccharides have been identified so far. Now a Max Planck research team ...

The composition of cell walls varies depending on the function of the tissue and the species of plant. Primary cell walls surround expanding cells in young tissues, whereas thickened secondary cell ...

Graphical abstract illustrating APS-Lat-EXO-mediated activation of the PI3K → AKT → NF-κB pathway in J-Lat 10.6 cells, leading to HIV-1 transcription and viral reactivation signals. Latent HIV-1 ...

SAITAMA, Japan, April 22, 2026 — Most of the carbon fixed by plants through photosynthesis is ultimately stored in the cell wall, primarily in the form of polysaccharides such as cellulose, xylan, and ...

Polysaccharides—long chains of simple sugars—play central roles in biological systems, including supporting cell structure, storing chemical energy, and regulating cell recognition. But synthesizing ...

Conjugate vaccines are composed of bacterial polysaccharide antigens covalently linked to protein carriers, enabling T cell-dependent immune responses that induce high-affinity antibodies and ...

Hooking sugar molecules together to make strings called glycans—also known as oligosaccharides and polysaccharides—is one of synthetic chemistry’s most bedeviling challenges. Carbohydrates are ...

Albizzia julibrissin is a widely distributed plant in China. Its dried stem bark has been used in traditional oriental medicine to treat insomnia, diuresis, sthenia, ascaricide, and confusion.
