AFB1 is a common foodborne toxin known for its potent carcinogenicity. Danshen polysaccharide (DSP) is an active ingredient of Danshen, which has been demonstrated to possess support intestinal homeostasis and anti-inflammatory activities. We utilized New Zealand White rabbits as an animal model to examine the impact of co-exposure to DSP and AFB1 on the intestines, as well as their underlying mechanisms. The results indicate that DSP elevated the abundance of Oscillospira, Coprococcus, Alistipes, Akkermansia, Bacteroides, Odoribacter, Blautia and Parabacteroides, while decreased the abundance of Sutterella, and Desulfovibrio, correcting AFB1-induced intestinal microbiota dysbiosis and enhancing microbial diversity within the gut. Moreover, DSP reduced the levels of diamine oxidase (DAO), D-Lactate, and malondialdehyde (MDA), while upregulating the expression of total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-Px), zonula occludens-1 (ZO-1), occludin, claudin-4, mucin-2 (MUC2), and secretory immunoglobulin A (sIgA), thereby alleviating the oxidative stress and intestinal barrier dysfunction induced by AFB1. DSP downregulated jejunal lipopolysaccharide (LPS) levels and the mRNA expression and proteins abundance of toll-like receptor 4 (TLR4), myeloiddifferentiationfactor 88 (MyD88), and nuclear factor kappa-B (NF-κB), thereby inhibiting the jejunal inflammation induced by AFB1. In summary, DSP alleviates AFB1-induced jejunal injury by remodeling the gut microbiota, bolstering antioxidant capabilities within the jejunum, fortifying the intestinal barrier, and suppressing the TLR4-mediated release of pro-inflammatory cytokines.
