Abstract

The purpose of this research was to investigate the effects of Achyranthes bidentata polysaccharides (ABPS) on secretions and expressions of proinflammatory cytokines in piglets jejunum epithelial cells (IPEC-J2) under the immunological stress of lipopolysaccharide (LPS), and to explore the possible mechanism of ABPS to regulate the immune stress of IPEC-J2. The 4th and 5th passages of IPEC-J2 were selected and cultured with 0 (control), 300, 600, 900 and 1 200 μg/mL ABPS, respectively, and both with 10 μg/mL LPS. Each group had 12 replicates with 1proe as 1 replicate. After cultured for 72 h, secretions of proinflammatory cytokines[interleukin (IL-1), interleukin 6 (IL-6), interleukin 8 (IL-8) and tumor necrosis factor α (TNF-α)] were detected by enzyme linked immunosorbent assay (ELISA) method, expression levels of Toll-like receptor 4 (TLR4) and nuclear factor κB (NF-κB) mRNAs were detected by real time quantitive PCR, and expression levels of TLR4, NF-κB and phosphorylated nuclear factor κB (p-NF-κB) proteins were detected by Western blot method. The results showed as follows:compared with control group, secretions of IL-1, IL-6, IL-8 and TNF-α were significantly decreased in 300, 600, 900 and 1 200 μg/mL ABPS groups (P<0.05); 300 μg/mL ABPS group significantly reduced p-NF-κB protein expression level (P<0.05); 900 and 1 200 μg/mL ABPS group significantly reduced the expression levels of NF-κB and TLR4 mRNAs, and NF-κB protein (P<0.05). In conclusion, ABPS control the release of proinflammatory cytokines and relieve immune stress through TLR4/NF-κB signal transduction pathway, low concentration of ABPS reduce immune stress by inhibiting NF-κB phosphorylation process, high concentration of ABPS alleviate immune stress by inhibiting TLR4 mRNA, NF-κB mRNA and NF-κB protein expressions.
