摘要:

目的: 研究免疫球蛋白D(immunoglobulinD,IgD)对人外周血诱导的单核-巨噬细胞功能的影响。方法: 收集类风湿关节炎(rheumatoid arthritis,RA)患者和健康对照者静脉血,分离人外周血单个核细胞(peripheral blood mononuclear cells,PBMCs),贴壁后用巨噬细胞集落刺激因子(macrophage colony-stimulating factor,M-CSF)刺激,流式细胞术检测RA患者和健康对照者外周血单核-巨噬细胞表面IgD Fc受体(FcδR,IgDR)的表达。给予不同浓度的IgD(终浓度1、3、10 μg/mL)刺激48 h,流式细胞术检测单核-巨噬细胞表面CD86、CD206的表达;流式细胞术检测单核-巨噬细胞的吞噬能力。结果: 人外周血单核-巨噬细胞表面连续表达FcδR,相较于健康对照者,RA患者外周血的表达更高(P<0.01)。IgD可增加M1型巨噬细胞的百分比(P<0.01),同时,巨噬细胞的吞噬能力也随着IgD水平的升高而增强(P<0.01)。结论: IgD可能通过结合FcδR促进人外周血诱导的单核-巨噬细胞向M1型极化,引起 M1、M2型巨噬细胞比例的失衡,并增强巨噬细胞的吞噬能力。

Abstract:

AIM: To investigate the effects of immunoglobulin D (IgD) on the function of human peripheral blood macrophages. METHODS: Peripheral blood mononuclear cells (PBMCs) were isolated from rheumatoid arthritis (RA) patients and healthy controls, and then adhered to the wall and stimulated with macrophage colony-stimulating factor (M-CSF). Flow cytometry was used to detect the expression of IgD Fc receptors (FcδR, IgDR) on the surface of peripheral blood mononuclear macrophages in RA patients and healthy controls. Stimulate macrophages with different concentrations of IgD (final concentrations of 1, 3, 10 μg/mL) for 48 hours, and flow cytometry was used to detect the expression of CD86 and CD206 on the surface of macrophages. Flow cytometry was used to detect the phagocytic of macrophages. RESULTS: Continuous expression of FcδR was detected on macrophages induced by peripheral blood mononuclear cells, and the expression was higher in RA patients than in healthy controls. The expression of M1 macrophages can be enhanced by IgD, while the expression of M2 macrophages can be weakened. At the same time, the phagocytic ability of macrophages are also enhanced with the increase of IgD levels. CONCLUSION: IgD may promote macrophage polarization in human peripheral blood monocytes by binding to FcδR, causing an imbalance in the proportion of M1 and M2 macrophages and enhancing phagocytic function of macrophages.
