Chinese giant salamander iridovirus (GSIV) is the causative pathogen of Chinese giant salamander (Andrias davidianus) iridovirosis, leading to severe infectious disease and huge economic losses. However, the infection mechanism by GSIV is far from clear. In this study, a Chinese giant salamander muscle (GSM) cell line is used to investigate the mechanism of cell death during GSIV infection. Microscopy observation and DNA ladder analysis revealed that DNA fragmentation happens during GSIV infection. Flow cytometry analysis showed that apoptotic cells in GSIV-infected cells were significantly higher than that in control cells. Caspase 8, 9, and 3 were activated in GSIV-infected cells compared with the uninfected cells. Consistently, mitochondria membrane potential (MMP) was significantly reduced, and cytochrome c was released into cytosol during GSIV infection. p53 expression increased at an early stage of GSIV infection and then slightly decreased late in infection. Furthermore, mRNA expression levels of pro-apoptotic genes participating in the extrinsic and intrinsic pathway were significantly up-regulated during GSIV infection, while those of anti-apoptotic genes were restrained in early infection and then rose in late infection. These results collectively indicate that GSIV induces GSM apoptotic cell death involving mitochondrial damage, caspases activation, p53 expression, and pro-apoptotic molecules up-regulation.

Abstract By using of the double antibody sandwich method of ELISA, the activities of five cytokines including IL-2, IL-4, IFN-α, IFN-β and TNF-α from the blood serum, liver, intestine and spleen at two developmental stages of Chinese giant salamander (Andrias davidianus) were determined to analyze the distribution of the cytokines. The result indicated that five cytokines were found in these four tissues, while their activities were different in different tissues and different ages. The highest activity of IL-2 and IL-4 was all present in blood serum of two different ages. The activity of IFN-α was the highest in blood serum of 1-year-old and in spleen of 2-year-old, respectively. The activity of IFN-β was also highest in blood serum of two different ages. The activity of TNF-α was highest in liver of two different ages. Thus, this study provides convincing reference for blood serum and liver as the most important distribution area of Chinese giant salamander.
