摘要:

为证实传染性法氏囊病毒(IBDV)感染SPF雏鸡后,其免疫器官细胞凋亡与bcl-2 mRNA动态表达的关系,应用TUNEL和实时荧光定量PCR方法分别对雏鸡免疫器官细胞凋亡数量和bcl-2 mRNA表达的动态变化进行了检测,结果发现,IBDV感染雏鸡后3~7 d,法氏囊、胸腺和脾脏中凋亡细胞数量显著或极显著高于相应对照雏鸡(P<0.01或P<0.05);同时在上述3种免疫器官中bcl-2 mRNA的表达均不同程度增加,并于病毒感染后3~7 d差异显著或极显著(P<0.01或P<0.05)。表明IBDV可增加感染雏鸡免疫器官的细胞凋亡数量和bcl-2 mRNA的表达。

Abstract:

Apoptosis and expression of bcl-2 mRNA in the immune organs of chicks infected with infectious bursal disease virus (IBDV) were investigated. The number of apoptosis cells was assessed by TUNEL method. The expression of bcl-2 mRNA was investigated by Real-time PCR. The results showed that the apoptosis cells in bursa of Fabricius, thymus and s pleen of chicks infected with IBDV from the third to seventh day post infection are significant or extremely significant higher than that of normal SPF chicks (P<0.01 or P<0.05).At the same time, the expression of bcl-2 mRNA significantly increased in the immune organs of SPF chicks infected with IBDV from the third to seventh day post infection compared with those of normal chicks (P<0.01 or P<0.05). These study indicates that IBDV can improve the number of apoptosis and the expression of bcl-2 mRNA in immune organs of chicks infected with IBDV.
