Superinduction of cytokine gene transcription by ciprofloxacin
In addition to their antibacterial properties, certain antibiotics are also biologic response modifiers. The fluorinated 4-quinolone, ciprofloxacin, for example, up-regulates IL-2 and IFN-γ production in PBLs stimulated in vitro. In the present study, ciprofloxacin was shown to increase the levels of mRNA for IL-1α, IL-2 and its receptor, IFN-γ, IL-3, IL-4, granulocyte- macrophage/CSF, TNF-α, and
