Abstract:
:Bee venom (BV) has been used in patients with rheumatoid arthritis, a condition characterized by rheumatoid joint destruction mediated, in large part, by matrix metalloproteinases (MMPs). We investigated the effects of melittin, a major component of bee venom, on the production of MMPs in human rheumatoid arthritic fibroblast-like synoviocytes (FLS). Lipopolysaccharide (LPS)-stimulated MMP3 production was significantly inhibited by melittin, which also inhibited LPS-induced DNA binding by nuclear factor kappaB (NF-kappaB). Mellitin had no effect on IL-1beta- or TNF-alpha-induced MMP1 or MMP3 production and did not decrease LPS-induced secretion of MMP1. Taken together, these findings suggest that melittin may exert its anti-rheumatoid effects, at least in part, by inhibiting MMP3 production, most likely through inhibition of NF-kappaB activity.
