Accumulation of ciprofloxacin and minocycline by cultured human gingival fibroblasts.
Through a mechanism that is unclear, systemic fluoroquinolones and tetracyclines can attain higher levels in gingival fluid than in blood. We hypothesized that gingival fibroblasts take up and accumulate these agents, thereby enhancing their redistribution to the gingiva. Using fluorescence to monitor transport activity, we characterized the accumulation of fluoroquinolones and tetracyclines in...
متن کاملEFFECTS OF DIFFERENT MEDIATORS ON FIBROBLAST PROLIFERATION
In this study, we have investigated the proliferative response of human dermal fibroblasts isolated from normal and psoriatic individuals to different cytokines. We found that IL-1, TNF (α) and EGF are stimulatory whereas IFN « and 1 both showed inhibitory activity on fibroblast proliferation. IL-6 a more recently described cytokine, showed no detectable effects on cell proliferation. Inve...

متن کاملModulation of alveolar macrophage-driven fibroblast proliferation by alternative macrophage mediators.
Tissue fibrosis results, in part, from an interaction between growth regulatory molecules released by mononuclear phagocytes and fibroblasts. In the chronic interstitial lung disorders, alveolar macrophages, the mononuclear phagocytes of the lung, are known to spontaneously release two growth factors for fibroblasts, fibronectin and alveolar macrophage-derived growth factor (AMDGF) that togethe...
متن کاملImpairment of gingival fibroblast adherence by IL-6/sIL-6R.
Interleukin-6 (IL-6) binds to human gingival fibroblasts (HGF) in the presence of a soluble form of IL-6 receptor (sIL-6R). We investigated the effects of IL-6 on the functions of HGF in the presence of sIL-6R. HGF changed their morphology from spindle-shaped to round, and detached from the culture dish by stimulation with IL-6/sIL-6R. In this condition, a signal transducer gp130 and a transcri...
