Monocyte chemoattractant protein-1 (MCP-1) seems to be involved in the pathogenesis of multiple sclerosis (MS). We found that in unstimulated (PHA(-)) and PHA-stimulated (PHA(+)) peripheral blood mononuclear cells (PBMC), MCP-1 and TNFalpha levels are higher in stable untreated MS patients. Interferon gamma (IFNgamma) is higher in relapsing patients in PHA(-) cultures and in stable patients in PHA(+) cultures. Chronic IFNbeta-1b treatment down-regulates TNFalpha, IFNgamma and MCP-1 production except for TNFalpha in relapsing patients. IFNbeta-1b, in vitro, increases MCP-1, TNFalpha and IFNgamma spontaneous production in all patients. Multivariate analysis suggests that MCP-1 production is dependent from clinical status and not from TNFalpha and IFNgamma production. Logistic regression analysis shows that MCP-1 production is significantly modified by treatment. Further studies are needed to clarify the role of MCP-1 in MS.
单核细胞趋化蛋白-1(MCP-1)似乎参与了多发性硬化症(MS)的发病机制。我们发现,在未刺激(PHA(-))和PHA刺激(PHA(+))的外周血单个核细胞(PBMC)中,稳定期未经治疗的MS患者的MCP-1和TNFα水平较高。在PHA(-)培养的复发患者和PHA(+)培养的稳定患者中,干扰素γ(IFNγ)水平较高。慢性IFNβ-1b治疗可下调TNFα、IFNγ和MCP-1的产生,但复发患者的TNFα除外。体外实验中,IFNβ-1b可增加所有患者的MCP-1、TNFα和IFNγ的自发产生。多变量分析表明,MCP-1的产生取决于临床状态,而非TNFα和IFNγ的产生。逻辑回归分析显示,治疗可显著改变MCP-1的产生。需要进一步研究以阐明MCP-1在MS中的作用。
