摘要 目的 观察干扰素(IFN)-γ、白细胞介素(IL)-4对狼疮肾炎(LN)患者外周血单个核细胞(PBMC)巨噬细胞炎症蛋白-1α(MIP-1α)产生的效应,以探讨Th1、Th2 因子是否对 LN MIP-1α产生具有调控作用。方法 Elisa方法检测细胞培养上清液MIP-1α,RT-PCR检测 MIP-1αmRNA。结果 (1)IFN-γ增强 LN患者 PBMC MIP-1α蛋白及mRNA产生。(2)IL-4抑制 LN患者PBMC MIP-1α蛋白及mRNA产生。(3)IFN-γ、IL-4对正常组MIP-1α产生无显著效应。结论IFN-γ增强LN患者PBMC MIP-1α产生而IL-4抑制 MIP-1α产生。 Objective To investigate the effects of IFN-γ and IL-4 on MIP- α production of peripheral blood mononuclear cells (PBMC) in lupus nephritis (LN) Methods MIP-1α expression in supematants was determined by Elisa and MLP-lα mRNA in PBMC was detected by RT-PCR. Results (1) IFN-γ increased MIP-1α prouduction of PBMC in LN. (2) IL-4 inhibited MIP-1α production of PBMC in LN. (3) No significant effect on PBMC in controls was found by either IFN-γ or IL-4. Conclusion IFN-γ enhances MLP- 1α production of PBMC in LN wherease LL-4 inhibits it.
