ABSTRACT
As in Iranian traditional medicine, bee venom [BV] is a promising treatment for the rheumatoid arthritis [RA] which is considered as a problematic human chronic inflammatory disease in the present time. Smoking is considered to be a major risk factor in RA onset and severity. The main aim of this study is to investigate the effects of BV on cigarette smoke-induced inflammatory response in fibroblast-like synoviocytes [FLS]. Cytotoxicity of cigarette smoke condensate [CSC] and bee venom were determined by the tetrazolium [MTT] method in cultured synovial fibroblastes. The expression of interleukin-1 beta and sirtuin1 mRNA were analyzed by SYBR green real-time quantitative PCR. Differences between the mean values of treated and untreated groups were assessed by student t-test. Based on MTT assay, CSC and BV did not exert any significant cytotoxic effects up to 40 micro g/mL and 10 micro g/mL, respectively. Our results showed that interleukin-1 beta mRNA level was significantly up-regulated by CSC treatments in LPS-stimulated synoviocytes in a dose-dependent manner. Conversely, the expressions of IL-1 beta and Sirt1 were up-regulated even in lower concentrations of BV and attenuated at higher concentrations. Also, BV attenuated the CSC-induced and LPS-induced inflammatory responses in synovial fibroblasts. Our results support the epidemiological studies indicating pro-inflammatory effects of CSC and anti-inflammatory effects of BV on FLS cell line
