Background: This study investigated the anti-inflammatory effects of bee venom (BV) through the inhibition of nuclear factor kappa beta ($NF-{\kappa}B$) expression in macrophages and keratinocytes. Methods: Cell viability assays were performed to investigate the cytotoxicity of BV in activated macrophages [lipopolysaccharide (LPS)] and keratinocytes [interferon-gamma/tumor necrosis factor-alpha ($IFN-{\gamma}/TNF-{\alpha}$)]. A luciferase assay was performed to investigate the cellular expression of $NF-{\kappa}B$ in relation to BV dose. The expression of $NF-{\kappa}B$ inhibitors ($p-I{\kappa}B{\alpha}$, $I{\kappa}B{\alpha}$, and p50 and p65) were determined by Western Blot analysis, and the electromobility shift assay. A nitrite quantification assay was performed to investigate the effect of BV, and $NF-{\kappa}B$ inhibitor on nitric oxide (NO) production in macrophages. In addition, Western Blot analysis was performed to investigate the effect of BV on the expression of mitogen-activated protein kinases (MAPK) in activated macrophages and keratinocytes. Results: BV was not cytotoxic to activated macrophages and keratinocytes. Transcriptional activity of $NF-{\kappa}B$, and p50, p65, and $p-I{\kappa}B{\alpha}$ expression was reduced by treatment with BV in activated macrophages and keratinocytes. Treatment with BV and an $NF-{\kappa}B$ inhibitor, reduced the production of NO by activated macrophages, and also reduced $NF-{\kappa}B$ transcriptional activity in activated keratinocytes (compared with either BV, or $NF-{\kappa}B$ inhibitor treatment). Furthermore, BV decreased p38, p-p38, JNK, and p-JNK expression in LPS-activated macrophages and $IFN-{\gamma}/TNF-{\alpha}$-activated keratinocytes. Conclusion: BV blocked the signaling pathway of $NF-{\kappa}B$, which plays an important role in the inflammatory response in macrophages and keratinocytes. These findings provided the possibility of BV in the treatment of atopic dermatitis.
