摘要:

目的: 初步探讨黑色素瘤缺乏因子2(absent in melanoma 2, AIM2)在急性胰腺炎(acute pancreatitis, AP)模型中的表达。方法: 利用雨蛙素建立小鼠急性胰腺炎动物模型,实验分组为对照组与AP组,利用实时荧光定量PCR(Q-PCR)与Western blot检测两组动物外周血单核细胞(peripheral blood mononuclear cells,PBMCs)中AIM2,白介素-1β(IL-1β)与白介素-18(IL-18)mRNA基因与蛋白的表达情况;利用ELISA法检测两组动物外周血单核细胞培养基中IL-1β与IL-18的含量。结果: Q-PCR与Western blot结果显示,与对照组相比较,AIM2、IL-1β及IL-18 mRNA与蛋白在AP组PBMCs中的表达显著升高(P<0.01);ELISA检测结果显示,AP组PBMCs合成分泌的IL-1β、IL-18的量显著高于对照组PBMCs合成分泌的量(P<0.01)。结论: AIM2在AP模型PBMCs的表达升高,表明其形成的炎症小体在这些细胞被激活,进而促进炎症因子IL-1β与IL-18的产生,因此,AIM2可能成为临床AP治疗潜在的治疗靶点。

Abstract:

AIM: To explore the expression of absent in melanoma 2 (AIM2) in pancreas in acute pancreatitis (AP).  METHODS: Caerulein was used to set AP mice model, which were then divided into the control group and the AP group. Q-PCR and Western blot were used to detect AIM2, IL-1beta and IL-18 mRNA and protein expression in peripheral blood mononuclear cells (PBMCs). ELISA method was used to detect the concentration of IL-1beta and IL-18 in culture supernatants of PBMCs. RESULTS: Q-PCR and Western blot showed that compared with the control group, the expression of AIM2, IL-1β and IL-18 mRNA and protein in PBMCs AP group increased significantly (P<0.01). ELISA test results showed that compared with the control group, the concentration of IL-1beta and IL-18 from culture supernatants of PBMCs in AP group increased significantly (P<0.01). CONCLUSION: The higher expression of AIM2 in PBMCs of AP showed activation of the AIM2 inflammasome in PBMCs results in exacerbated IL-1beta and IL-18 production. Therefore, AIM2 might be a potential therapeutic target in clinical AP treatment.
