1 In vitro anti-inflammatory effects and immunomodulation by gemifloxacin in stimulated human THP-1 monocytes. Gemifloxacin GLI family zinc finger 2 Homo sapiens
2 The effects of gemifloxacin on DNA synthesis and killing of S. aureus was assessed in bacteria alone and in those bacteria phagocytosed by THP-1 monocytes over 24 h. Gemifloxacin in stimulated THP-1 monocytes over the first 30 min caused an increase in c-AMP, NO, H2O2 and TNFalpha levels and protein kinase C, NADPH oxidase, glutathione reductase, NAG and cathepsin D activities.

3 The effects of gemifloxacin on DNA synthesis and killing of S. aureus was assessed in bacteria alone and in those bacteria phagocytosed by THP-1 monocytes over 24 h. Gemifloxacin in stimulated THP-1 monocytes over the first 30 min caused an increase in c-AMP, NO, H2O2 and TNFalpha levels and protein kinase C, NADPH oxidase, glutathione reductase, NAG and cathepsin D activities. Gemifloxacin GLI family zinc finger 2 Homo sapiens
4 These effects were at a higher magnitude at 24 h. Gemifloxacin initiates a phagocyticidal effect of THP-1 monocytes at an early time of 30 min which plays a role in killing bacteria but a higher magnitude of killing of bacteria occurs later by a standard static mechanism.
