| 英文摘要 | Aim: To establish an in vitro injured motor neuronal model and investigate the neuroprotective effects and possible mechanism of celecoxib a selective, cyclooxygenase-2 (COX-2) inhibitor, on this model. Methods: After macrophages were stimulated with lipopolysaccharide (LPS)+interferon-gamma (IFN-gamma) in the presence or absence of celecoxib for 24 h, the cell-free supernatant of LPS-stimulated macrophages was transferred to the culture of NSC34 cells. Viability of NSC34 cells was assessed by MTT assay after a further 24 h and 72 h incubation. After macrophages were stimulated by LPS+IFN-gamma for 12 h or 24 h, the release of prostaglandin E-2 (PGE(2)), nitric oxide (NO), reactive oxygen species (ROS), tumor necrosis factor alpha (TNF-alpha) and interleukin-1 beta (IL-1 beta) from macrophages was measured by radioimmunoassay, Griess assay, fluorescence assay and enzyme-linked immunosorbent assay, respectively. The mRNA levels of COX-2, inducible nitric oxide synthase (iNOS), TNF-alpha and IL-1 beta in macrophages were determined by reverse transcription-polymerase chain reaction after macrophages were stimulated for 6 h and 12 h. Results: The supernatant of LPS-stimulated mouse macrophages induced the death of NSC34 cells and celecoxib protected the NSC34 cells against this toxicity. The LPS-induced increases in the release of PGE(2), NO, TNF-alpha and IL-1 beta from macrophages were attenuated by pre-treatment with celecoxib. However, celecoxib showed no effect on the ROS levels upregulated by LPS+IFN-gamma in the macrophage supernatant. The mRNA levels of COX-2, iNOS, TNF-alpha and IL-1 beta were increased in LPS-activated macrophages and, except COX-2, reduced by pre-treatment with celecoxib. Conclusion: An in vitro injured motor neuronal model was established by using the toxicity of LPS-stimulated mouse macrophages toward motor neuronal NSC34 cells. In this model, celecoxib exerted neuroprotective effects on motor neurons via an inhibition of the neurotoxic secretions from activated macrophages. |
