title: Madimadi, Korean folk medicine, blocks TNF-alpha, IL-1beta, and IL-8 production by activated human immune cells.
abstract: Madimadi, a Korean folk medicine, has been applied to treat rheumatoid arthritis (RA). However, its mechanisms of action have not been examined. The involvement of inflammatory cytokines, particularly TNF-alpha, IL-1beta, and IL-8, resulting in local inflammation in the pathogenesis of RA is now widely accepted. Madimadi dose-dependently inhibited TNF-alpha, IL-1beta, and IL-8 production from activated human mast cells (HMC-1). RT-PCR revealed inhibition of TNF-alpha and IL-1beta transcription in activated HMC-1. In addition, we confirmed potent inhibition of TNF-alpha and IL-1beta production by Madimadi using purified human blood PBMC from an active RA group, but not from healthy or disease control groups. These novel insights into the immunosuppressive action of Madimadi are likely to impact the clinical use of this agent.
