Cefodizime, a third cephalosporine, was originally developed for use in infectious disease as an advanced antibiotics. Cefodizime has also been known to play a meaningful role in activating natural killer properties of immune cells as well as enhancing immunological parameters such as phagocytosis. Furthermore, as the infection can result in remarkable changes for homeostatic mediators, it is expected that cefodizime may initiate the strong immuno- modualtory effect. In the present work, we investigated whether cefodizime has a biphasic effect of anti-bacteria and immunomodulation via macrophage. For the study, we isolated mouse peritoneal macrophages and treated with cefodizime 10㎍/㎖, 50㎍/㎖, 100㎍/㎖, IFN-v 10U/㎖.＋LPS l㎍/㎖ Cells were then incubated for 4, 8, 12, and 24hrs to analysis the expression of IL-1, IL-6, IL-12 mRNA from macrophages. The results showed that cytokines were expressed more than that of control in a time-dependent manner and 100㎍/㎖ cefodizime group showed the greatest expression as much as the positive control (IFN-v＋LPS)showed at 24h. In conclusion, cefodizime can play a significant role for the expression of pro-inflammatory cytokines, IL-1, IL-6, and IL-12 in earlier stage so that macrophages and other immune cells can response to the infectious substances, immediately. Moreover, when such pro-inflammatory cytokines are increased, we can also expect that the enhancement of cell-cell interaction of NK cell, CTL and B cell by cefodizime can affect the immunomodulatory effect along with its major role in anti-bacterial effect.
