摘  要:目的探讨特应性皮炎(AD)患者外周血单个核细胞(PBMC)培养上清液分泌的白细胞介素4(IL-4)、γ干扰素(IFN-γ)、白细胞介素10(IL-10)和T细胞转化因子β(TGF-β)水平,及苯烯莫德对这些因子的调节作用。方法分离培养20例AD患者和20例健康对照的外周血单个核细胞,再将20例AD患者外周血单个核细胞等分为4组,分别给以磷酸缓冲盐液(PBS),400nmol/L苯烯莫德溶液,250nmol/L地塞米松溶液,10nmol/L他克莫司溶液共培养后,酶联免疫吸附法检测细胞培养上清液分泌IL-4、IFN-γ、IL-10、TGF—β的水平。结果AD组和健康对照组外周血IL-4浓度分别为(83.4±12.2)pg/ml和(44.3±5.7)pg/ml,两组比较,P〈0.05;TGF-β浓度分别为(178.9±17.40)pg/ml和(158.7±18.30)pg/ml,两组比较,P〉0.05。AD组和健康对照组外周血IFN-γ浓度分别为(12.5±2.3)pg/ml和(25.4±3.4)pg/ml,两组比较,P〈0.05;IL-10浓度分别为(144.4±4.1)pg/ml和(189.9±6.5)pg/ml,两组比较,P〈0.05。400nmol/1苯烯莫德可降低AD患者外周血IL-4、IL-10、IFN-γ的含量,PBS对照组和苯烯莫德组IL-4浓度分别为(83。3±12.2)pg/ml和(50.2±10.1)pg/ml,两组比较,P〈0.05;IL-10的浓度分别为(144.4±4.1)pg/ml和(124.7±17.5)pg/ml,两组比较,P〉0.05;IFN-γ的浓度分别为(12.5±2.3)pg/ml和(9.56±5.1)pg/ml,两组比较,P〉0.05。苯烯莫德组与地塞米松组,他克莫司组相比,差异无统计学意义(均P〉0.05)。苯烯莫德组可升高PBS对照组AD患者外周血TGF—β含量,PBS对照组和BVM组TGF-β的浓度分别为(178.9±17.4)pg/ml和(203.6±15。3)pg/ml,两组比较,P〉0.05。苯烯莫德组与地塞米松组,他克莫司组相比,差异无统计学意义(均P〉0.05)。结论苯烯莫德可调Objective To detect levels of interleukin-4 (IL-4), IL-10, interferon-γ (INF-γ) and transforming growth factor-β (TGF-β) in the culture supernatant of peripheral blood mononuclear cells (PBMCs) from patients with atopic dermatitis (AD), and to evaluate regulatory effects of benvitimod on these cytokines. Methods PBMCs were isolated from 20 AD patients and 20 healthy controls. Then, PBMCs from AD patients were equally divided into 4 groups to be cultured with phosphate-buffered saline (PBS group), 400 nmol/L benvitimod solution (benvitimod group), 250 nmol/L dexamethasone solution (dexamethasone group) and 10 nmol/L tacrolimus solution (tacrolimus group), respectively. Enzymelinked immunosorbent assay (ELISA) was performed to detect levels of IL-4, IL-10, INF-γand TGF-β in the culture supernatant of PBMCs. Results Compared with healthy controls, patients with AD showed significantly higher level of IL-4 (83.4 ± 12.2 vs. 44.3 ± 5.7 pg/ml, P 〈 0.05), but lower levels of INF-γ (12.5 ± 2.3 vs. 25.4 ± 3.4 pg/ml, P 〈 0.05) and IL-10 (144.4± 4.1 vs. 189.9 ± 6.5 pg/ml, P 〈 0.05) in peripheral blood. However, no significant difference in the level of TGF-β was observed between the patient group and control group (178.9 ± 17.40 vs. 158.7± 18.30 pg/ml, P 〉 0.05). Compared with PBS, 400 nmol/L benvitimod could decrease the expression of IL-4 (50.2 ± 10.1 vs. 83.3 ± 12.2 pg/ml, P 〈 0.05), IL-10 (124.7 ± 17.5 vs. 144.4 ± 4.1 pg/ml, P 〉 0.05) and INF-γ (9.56 ± 5.1 vs. 12.5 ± 2.3 pg/ml, P 〉 0.05), but increase the expression of TGF-β (203.6 ± 15.3 vs. 178.9 ± 17.4 pg/ml, P 〉 0.05) by PBMCs. In addition, no significant differences in the expression of IL-4, IL-10, INF-γ or TGF-β were observed between the benvitimod group and dexamethasone group or tacrolimus group (all P 〉 0.05). Conclusion Benvitimod can regulate the expression of IL-4, IL-10, INF-γ/and TGF-β by PBMCs in patients with AD.
