摘要： Heat shock proteins (HSPs), such as HSP70 and HSP90, are a suite of highly conserved proteins produced in all cellular organisms when they are exposed to stresses. In aquatic animals, they have been proved to play important roles in response to environmental pollutants and particularly in the non-specific immune responses to pathogen infections. In the present study, the expression profiles of HSP70 and HSP90 genes in hemocytes and hepatopancreas from the ridgetail white prawn Exopalaemon carinicauda infected with WSSV and Vibrio anguillarum were detected using reverse transcription polymerase chain reaction (RT-PCR). After WSSV challenge, the expression level of HSP 70 gene transcripts in the hemocytes and hepatopancreas increased to peak level at 6 h and 48 h, respectively. HSP90 gene transcripts in hemocytes and hepatopancreas were up-regulated significantly at 12 h and 6 h, respectively. During V. anguillarum challenge, the mRNA content of HSP70 gene in hemocytes and hepatopancreas increased significantly at 12 h and 6 h post-infection, respectively. The expression level of HSP90 gene both in hemocytes and hepatopancreas were up-regulated in the first 3 h. The expression patterns of HSP70 and HSP90 genes in hemocytes and hepatopancreas showed temporal and spatial differences after challenged with WSSV and V. anguillarum. The results suggested that HSPs might be involved in immune responses to pathogens challenge in E. carinicauda.
