Structural characterization and immunomodulatory activity of an acidic heteropolysaccharide isolated from the fermented burdock residue mediated by Rhizopus nigricans

In vivo evaluations of Lactobacillus-fermented Eucheuma spinosum polysaccharides on alleviating food allergy activity

“…Importantly, RBAPS ameliorated intestinal integrity and function by promoting the expression of occludin, claudin-5, Atg5, and Atg7, activating the TLR4/MAPK signaling pathway in CTX-induced mice. 4 The research results of Su et al showed that fermented Hericium erinaceus polysaccharides significantly increased the levels of IgA, IgG and IgM and decreased the levels of TNF-α, IL-1 and IL-6 (p < 0.05). Immunohistochemical results showed that both polysaccharides significantly increased the expression of occludin, ZO-1, ZO-2, claudin-3, claudin-4, and MUC2 and decreased claudin-2.…”
