Our study aimed to evaluate the effects of Gal-1 in dose depending manner on maturation and immunomodulatory properties of monocyte-derived (Mo) DCs . The effects were analyzed by monitoring their phenotypic characteristics, cytokine profile, and the ability to direct the immune response in the co-culture with allogeneic CD4T cells. Gal-1 reduced the expression of CD80 and CD86 molecules on MoDCs compared to untreated MoDCs. Gal-1 at concentrations of 1 and 6 μg/mL significantly reduced IL-12 production, while the concentration of 3 μg/mL led to its significant increase. Gal-1 in all concentrations induced a significant increase in the production of IL-10. Treatment of MoDCs with 3 and 6 μg/mL of Gal-1 stimulated the production of IL-2 and IFN-γ in the co-culture with CD4T lymphocytes. This study demonstrated a dual immunomodulatory effect of Gal-1 on MoDCs in terms of immune stimulation and immune suppression, depending on the applied concentration.
我们的研究旨在评估不同剂量的Gal-1对单核细胞来源的(Mo)树突状细胞(DCs)成熟及免疫调节特性的影响。通过监测其表型特征、细胞因子谱以及在与同种异体CD4T细胞共培养中指导免疫反应的能力来分析这些影响。与未处理的MoDCs相比,Gal-1降低了MoDCs上CD80和CD86分子的表达。浓度为1和6μg/mL的Gal-1显著降低了IL-12的产生,而3μg/mL的浓度则导致其显著增加。所有浓度的Gal-1均诱导IL-10产生显著增加。用3和6μg/mL的Gal-1处理MoDCs可刺激其在与CD4T淋巴细胞共培养时产生IL-2和IFN-γ。这项研究表明,根据所应用的浓度,Gal-1对MoDCs具有免疫刺激和免疫抑制方面的双重免疫调节作用。
