Abstract:
PURPOSE: Platycodon grandiflorum (PG) is known to have effective antimicrobial and anticancer activity. The main bioactive components of PG are saponins, and these could contribute to anti-inflammatory activity. However, little is known about the anti-inflammatory effect of PG. In this study, we aim to assess the anti-inflammatory response to Red PG Extract (RPGE) in splenocytes under ex vivo conditions. METHODS: The cell viability of isolated splenocytes taken from mice was analyzed by performing a Cell Counting Kit-8 assay. The productions of nitric oxide (NO) and cytokines (specifically interleukin-6 (IL-6) and interleukin-10 (IL-10)) were measured utilizing Griess reagent and ELISA, respectively. RESULTS: We found that co-treatment with RPGE and Lipopolysaccharide (LPS) decreased isolated splenocyte proliferation as compared with that of the LPS-stimulated control. We also observed that RPGE markedly suppressed NO synthesis and IL-6 production that was induced by LPS. There were no significant differences of IL-10 production between co-treatment with RPGE plus LPS and treatment with LPS alone. CONCLUSION: When taken together, our data has shown that RPGE mitigates LPS-induced inflammation in splenocytes isolated from mice. Further research is surely needed to confirm the anti-inflammation effects of RPGE in an in vivo model.
