目的:探究前列腺素E2(PGE2)的EP4受体阻断剂L161982对胶原诱导性关节炎( CIA)小鼠发病的影响及其机制。方法将雌性DBA/1小鼠随机分为模型组、PGE2的EP4特异性受体阻断剂L161982组、对照组。免疫34 d后对各组小鼠进行关节炎病变指数评分、组织病理检查及滑膜炎症评分,通过ELISA方法检测小鼠血清白细胞介素17(IL-17)及单核细胞趋化蛋白-1(MCP-1)表达水平,通过流式细胞术检测淋巴结及脾 CD4+CD25+Foxp3+调节性T细胞( CD4+CD25+Foxp3+Treg)的数量。结果在初次免疫后第29、31、33、35天,L161982组关节炎指数显著低于模型组;L161982组滑膜炎症分数(1.81±1.70)分低于模型组(3.50±0.50)分。 L161982组的IL-17及MCP-1表达水平均显著低于模型组[IL-17:(13.52±3.90 vs 27.51±8.10) pg/ml, F=24.28, P <0.01;MCP-1:(15.80±2.10 vs 30.20±3.40) pg/ml,F=127.78,P <0.01]。 L161982组淋巴结及脾CD4+CD25+Foxp3+Treg细胞占CD4+T细胞之比例高于模型组[淋巴结:(4.21±0.52)%vs(3.31±0.36)%,F=27.46,P <0.01;脾:(2.63±0.41)%vs (1.67±0.14)%,F=29.43,P <0.01],差异具有统计学意义。结论 PGE2的EP4受体特异性阻断剂L161982可能通过抑制辅助性T细胞(Th17)分泌细胞因子IL-17,增加调节性T细胞的分化,以及降低趋化因子MCP-1表达来帮助减轻CIA病情。

Objective To investigate the effectsandmechanism of EP4 antagonist on the mice model of rheumatoid arthritis ( CIA) .Methods The DBA/1 female mice were randomly divided into the model group, the L161982 ( EP4 antagonist ) group and the control group.Thirty-four days after the injection, the arthritis score ( AS) , the histopathologic examination and the synovitis score were evaluated on the mice.The protein expression of interleukin-17 ( IL-17 ) and monocyte chemoattractant protein-1 ( MCP-1) was detected by ELISA.The quantity of CD4 +CD25 +Foxp3 +Treg cells were determined by flow cytometry.Results On day 29, 31, 33, 35 after the first immunization, the AS of the L161982 group was remarkably lower than that of the model group.The synovitis score of the L161982 group ( 1.80 ±1.70 ) was lower than that of the model group ( 3.50 ±0.50 ) .The expression levels of IL-17 [ ( 13.52 ±3.90 ) pg/ml] and MCP-1[(15.80 ±2.10) pg/ml] in the L161982 group were significantly lower than those in the model group[IL-17:(27.51 ±8.10) pg/ml, F=24.28, P<0.01;MCP-1:(30.20 ±3.40) pg/ml, F=127.78, P <0.01].The percentages of CD4 +CD25 +Foxp3+Treg cells in lymph nodes and spleens in the L161982 group were significantly higher than those in the model group [ lymph nodes ( 4.21 ± 0.52)%vs (3.31 ±0.36)%, F=27.46,P <0.01; spleens (2.63 ±0.41)% vs (1.67 ±0.14)%, F=29.43,P <0.01].Conclusion The L161982 (EP4 antagonist) might mitigate the disease o CIA by inhibiting the serum expression of IL-17 and MCP-1, as well as increasing the differentiation of Treg cells.
