摘要:

目的: 研究牡丹皮提取物丹皮酚对TLR2配体FSL-1刺激诱导慢性前炎因子释放的分子机制,为天然药物治疗慢性皮炎提供新的思路。方法: 将小鼠髓源性树突状细胞(DCs)分成5组,对照组、FSL-1刺激组、丹皮酚低、中、高剂量干预组(25、50、100 μg/mL),所有组均给予10 ng/mL rmIL-4环境培养,ELISA法检测树突状细胞培养上清液中IL-10、IL-12的含量,流式细胞术检测树突状细胞表面MHC-II、CD40和CD86分子表达的水平。结果: 各组树突状细胞表面分子表达水平:刺激组与对照组相比,树突状细胞表面MHC- II、CD40和CD86表达量明显增加(P<0.05)。丹皮酚干预组与刺激组相比,DCs表面MHC- II、CD40和CD86表达量均降低,且高、中剂量组具有统计学差异 (P<0.05)。细胞因子分泌水平:刺激组与对照组相比,抗炎性细胞因子IL-10的水平明显降低(P<0.05),而前炎细胞因子IL-12的水平明显升高(P<0.05);丹皮酚干预组与FSL-1刺激组相比,各个干预组的IL-10的分泌水平显著上升(P<0.05),丹皮酚干预组中IL-12的分泌水平均有下降,但仅高、中剂量组具有统计学差异(P<0.05)。结论: TLR2配体FSL-1可以和IL-4共刺激DCs,促进DCs活化并成熟,促进前炎性因子IL-12释放,抑制IL-10等抗炎细胞因子分泌,诱导CD4+T细胞向Th1分化,导致了Th1极化状态,诱导慢性皮肤炎症;而天然药物丹皮酚可抑制TLR2配体介导TLR2通路活化DCs这一过程,具有抑制皮肤慢性炎症的潜力。

Abstract:

AIM: To study the molecular mechanism of natural paeonol induced by TLR2 signal transduction pathway of inflammation of the skin, developing new ideas for prevention and treatment of atopic dermatitis and provide a theoretical basis. METHODS: Bone marrow-derived dendritic cells (BMDCs) were divided into three groups: control group, FSL-1 stimulated group, paeonol treatment group with different concentrations (25, 50, 100 g/mL). The DC surface molecules such as CD40, CD86 and MHC-II were detected by flow cytometry. The cytokine levels of IL-10, IL-12 in culture supernatant were detected by ELISA. RESULTS: The expression of CD40, CD86 and MHC-II on the surface of dendritic cell surface molecules were significantly increased after stimulated with FSL-1 as compared to control group (P<0.05). After treated with paeonol (50, 100 g/mL), expressions of CD40, CD86 and MHC-II were all decreased, only in the high and middle dose groups, the difference was statistically significant (P<0.05). Compared with the control group, FSL-1 stimulated group significantly enhanced the secretion of pro-inflammatory cytokines IL-12(P<0.05), while the anti-inflammatory cytokine IL-10 was decreased significantly (P<0.05). Meanwhile, compared with FSL-1 stimulated group, the levels of IL-12 were found significantly decreased in the middle and high dose of paeonol treatment group(P<0.05), but the low dose treatment group did not show significant effect(P>0.05). The above results showed that FSL-1 can change the differentiation of lymphocyte subset through affecting the secretion of DC cytokines, which can promote the pro-inflammatory cytokines such as IL-12 secretion, while the secretion of anti-inflammatory cytokines such as IL-10 were decreased. But paeonol reversed these effects. CONCLUSION: FSL-1, the TLR2 ligands, can promote the development of chronic dermatitis and chronic inflammation of the development through influencing the expression of cytokines production and maturation of DCs. The level of IL-12 is increased while level of IL-10 is decreased by activating the TLR2 signaling pathway. Furthermore, the primitive Th cells are promoted to transform to Th1 thereby resulting in Th1/Th2 polarization. However, paeonol can reverse FSL-1 induced cellular processes, and shows potential in the prevention and treatment of chronic dermatitis.
