论文摘要: |
Basic leucine zipper transcription factor ATF-like (BATF)-3, belonging to activator protein 1 (AP-1) superfamily transcription factors, is essential for homeostatic development of CD8 alpha(+) classical dendritic cells activating CD8 T-cell responses to intracellular pathogens. In this study, the characteristics and cDNA cloning of the CiBATF3 molecule were described in grass carp (Ctenopharyngodon idella). CiBATF3 had abundant expression in immune-related organizations, including liver, spleen and gill, and grass carp reovirus (GCRV) infection had significantly changed its expression level. After Ctenopharyngodon idella kidney (CIK) cells were challenged with pathogen-associated molecular patterns (PAMPs), polyinosinic:polycytidylic acid (poly(I:C)) stimulation induced higher mRNA levels of CiBATF3 than that of lipopolysaccharide (LPS). Subcellular localization showed that CiBATF3-GFP was entirely distributed throughout cells and nuclear translocation of CiBATF3 was found after poly(I:C) treatment. Additionally, the interaction between CiBATF3 and interleukin 10 (IL-10) was proven by bimolecular fluorescence complementation (BiFC) system. The small interfering RNA (siRNA)-mediated CiBATF3 silencing showed that the mRNA of CiBATF3 and its downstream genes were down-regulated in vitro and in vivo. CiBATF3 played a negative regulatory role in the transcriptional activities of AP-1 and NF-kappa B reporter gene. In summary, the results may provide valuable information on fundamental functional mechanisms of CiBATF3. |
