Purification, Structural Characterization, and Anticancer Activity of the Polysaccharide From Sea Red Rice Bran

Food Frontiers, Volume 7, Issue 2, March 2026.
Sea red rice bran polysaccharides were separated and purified by DEAE‐52 column chromatography, yielding three components: SRBP‐I, II, and III. Moreover, all three are pentosan‐type polysaccharides predominantly composed of mannose. Among them, SRBP‐I demonstrated the most potent inhibitory effect on HeLa cells. Further investigation indicated that the

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...
