英文摘要: Immune responses of fish are normally regulated by various cytokines and their encoding genes, which are generally called immune related genes. Expressions of different immune related genes of fish were previously proved to be effected by vaccination with various pathogens,including bacteria viruses, parasite, and so on. In the present study,the expressions of six immune related genes in liver,spleen and head kidney of grass carp, i. e. C-reactive protein (CRP) major histocompability complex I (MHC I), tumor necrosis factor alpha (TNF alpha), interleukin-1 beta (IL-1 beta) interleukin-8 (IL-8) and interferon I (IFN I) as well, were quantified using quantitative real-time polymerase chain reaction at 1, 7, 15 and 28 days post. intraperitoneal injection (dpi) with formalin killed Flavobacterium columnare G(4) (FKG(4)), respectively. Control fish were injected intraperitoneally with sterile phosphate buffer solution (PBS). The gene expression of CRP in liver of grass carp was detected at a higher level than that in either spleen or head kidney of fish, and was elevated significantly by vaccination with FKG(4) at 1 and 7 dpi, with the highest expression being observed at 1 dpi. By contrast, the gene expression of CRP in either spleen or head kidney of fish was detected at a relatively low level, with no significant difference being observed between vaccinated and control fish at all four detected time points. Significant higher gene expression of MHC I was observed at 1, 7 and 15 dpi in all three detected tissues of vaccinated fish when compared with control fish while its gene expression at 28 dpi showed no significant difference between vaccinated and control fish. Gene expression of TNF alpha in all three detected tissues of fish was detected at a quite low level, with a significant higher gene expression being observed at 1 and 7 dpi in detected tissues of vaccinated fish compared with control fish and its gene expression in three tissues of vaccinated fish at 15 and 28 dpi are at the same level as that of control fish. Gene expressions of IL-1 beta in liver and spleen of vaccinated fish were significantly enhanced at 1 dpi and then down-regulated to control level at 7, 15 and 28 dpi while its gene expression in head kidney was significantly elevated at 1 and 7 dpi and then decreased to control level at 15 and 28 dpi. Gene expressions of IL-8 in three tissues of vaccinated fish were significantly up regulated at 1 dpi, and then down regulated to control expression level in all detected tissues at 7, 15 and 28 dpi. However, the gene expression of IFN I, on the other hand, did not change significantly in all three detected tissues of vaccinated fish at four time points,although a slight increase of gene expression of IFN I in these tissues was also noticed at 1, 7 and 15 dpi. It is suggested that vaccination of FKG(4) be rather effective on increasing expressions of immune related genes in grass carp, which are mainly related to the fish immunity against infection of bacterial pathogen.
