초록
Interferon regulatory factors (IRFs) are a family of transcription factors essential to the control of antiviral immune response, cell growth, differentiation and apoptosis. IRF10 of zebrafish (Danio rerio) was negative regulation of the interferonΦ1 and 3 response in vitro. In this study, we analyze the induction of in vivo immune response activation from the IRF10 gene of zebrafish and the protective effect against VHSV. As the results, the group inoculated with IRF10 expression vectors, there was no expression of IFNΦ1, suggestion that IRF10 may function as a negative regulator of IRF3, which binds to the IFNΦ1 promoter. And other types of interferon genes (IFNΦ2–4) are thought to have been activated, inducing to the expression of pro-inflammatory cytokine and Mx genes. As the results of challenge test performed at 14 days after inoculation of the expression vectors, the maximum survival rate [50% (1μg DNA) and 42.5% (10μg DNA)] for IRF10 group were recorded. Meanwhile, the survival rates of pcDNA3.1 and PBS as the control groups were 10% and 15%, respectively. This study suggests that the possibility that activation of IRF10 molecule could be exploited as a VHS control method.
