Interleukin-1 (IL-1) is one of the proinflammatory cytokines, after IL-1 binds to IL-1RI, IL-1RacP (interleukin-1 receptor accessory protein) joins with IL-1/IL-1RI to form a complex, and leading to cell activation. IL-1RAcP is involved in immune response, stress and apoptosis. The purpose of this study was to investigate the gene expression of IL-1RAcP in red seabream (Pagrus major) exposure to low water temperature (8℃, 33 psu) and low salinity (20℃, 10 psu). Results showed that, the expression of IL-1RAcP was significantly increased in the experiment groups, such as low water temperature (8℃, 33 psu), and low salinity (20℃, 10 psu). These results suggest that IL-1RAcP was played roles in biomarker gene on the environmental stress such as low water temperature and low salinity.
