摘要: 目的探讨鼠3型肝炎病毒(MHV-3)诱导的慢性病毒性肝炎C3H/Hej小鼠肝组织白细胞介素-22(IL-22)和细胞因子信号抑制因子3(SOCS3)mRNA水平的变化。方法给C3H/Hej小鼠腹腔注射MHV-3(100 pfu),诱导慢性病毒性肝炎模型,采用实时荧光定量PCR 法检测MHV-3感染后0、5、10、15和20 d时小鼠肝组织IL-22和SOCS3 mRNA水平的变化。结果模型鼠肝组织IL-22和SOC3 mRNA水平在0 d时分别为(0.26±0.15)%和(6.35±2.21)%,在感染后10、15和20 d后IL-22水平分别为 (6.28±2.79)%、(2.50±1.24)%和(2.73±0.85)%,SOC3水平分别为(16.92±4.39)%、(14.06±4.09)%和(13.36±1.89)%,均较0 d时显著增高(P<0.05),且在第10 d达到最高峰。结论IL-22和SOCS3可能参与了MHV-3诱导的小鼠慢性病毒性肝炎的发生发展过程。

Abstract: Objective To investigate the changes of interleukin-22 (IL-22) and suppressor of cytokine signaling 3(SOCS3) mRNA in murine hepatitis virus 3(MHV-3) induced chronic viral hepatitis in C3H/Hej mice. Methods Chronic viral hepatitis in C3H/Hej mice was induced by intra-peritoneal injection of MHV-3 virus at dose of 100pfu. At day 0,5,10,15 and 20 post-infection,IL-22 and SOCS3 mRNA in the liver tissues were detected by real-time PCR. Results IL-22 and SOCS3 mRNA level in livers of model mice at day 0 were (0.26±0.15)% and(6.35±2.21)%,respectively. At day 10,15 and 20,IL-22 mRNA levels in the liver tissues were (6.28±2.79)%,(2.50±1.24)% and(2.73±0.85)%,respectively,and SOCS3 mRNA levels were(16.92±4.39)%,(14.06±4.09)% and (13.36±1.89)%,respectively, all of which were markedly increased than baseline(P<0.05). The mRNA levels of IL-22 and SOCS3 both peaked at day 10 post MHV-3 infection. Conclusions IL-22 and SOCS3 may play an important role in the pathogenesis of MHV-3-induced chronic viral hepatitis in mice.
