Abstract
This study aimed to determine the effect of soybean protein-derived peptides (SBP) on the inhibition of lipopolysaccharide (LPS)-induced RAW264.7 cell inflammation. The mRNA of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), Lymphocyte Antigen 96 (LY96), and nuclear factor-κB (NF-κB) were detected with RT-qPCR. The concentrations of cytokines (TNF-α, IL-6, and IL-1β) secreted were detected by ELISA Kit. The results indicated that SBP inhibited the inflammatory stress induced by LPS in RAW264.7 cells. Western blot analysis was used to examine this anti-inflammatory molecular mechanism. The findings showed that SBP impeded the increase of toll-like receptor 4 activity by restricting LY96, while also inhibiting the mitogen-activated protein kinase-c-Jun N-terminal kinase pathway in cells, as well as LPS-induced NF-κB activation caused by the degradation of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha (IκBα). Consequently, the release of pro-inflammatory cytokines (TNF-α, IL-6, and IL-1β) was inhibited, preventing LPS-induced inflammation of RAW 264.7 cells. Therefore, this research highlighted the potential application of SBP in the development of anti-inflammat...Continue Reading
