| 中文摘要 | CpG oligodeoxynucleotides (ODNs), the well-known vaccine adjuvant in mammals, have been proved to mount innate immune responses in crustaceans. In the present study, CpG ODNs was employed as supplements in diets to fed crab Eriocheir sinensis, and the changes of immune parameters as well as weight gain were investigated to evaluate its possible application in crab farming. After the crabs were fed with 40 mg/kg and 100 mg/kg CpG ODNs containing diets (designated as C40 and C100 group) for four weeks, the lysozyme activities were significantly enhanced (p < 0.01) in both groups, while the catalase activity was only increased (p < 0.01) in the C40 group. When those crabs were subsequently challenged with Aeromonas hydrophila, the cumulative mortalities in C40 and C100 groups were declined by 10.4% and 10.8% (p < 0.05) compared with that of control group, respectively. Interestingly, the final weights of crabs were increased after four weeks' feeding of CpG ODNs, and the percentage of weight gain in C40 group reached 124.5 +/- 14.2%, which was significantly higher (p < 0.05) than that of control group (78.1 +/- 19.2%) and C100 group (107.3 +/- 282%). The uptake of CpG ODNs by haemocytes and the possible mechanism of CpG ODNs to active the immune response were investigated by using the laser scanning confocal microscope. CpG ODNs (labeled with 5'-end-FAM) could be internalized by the haemocytes after incubation of 20 min, with strong signals detected at the cell membrane and in the cytoplasm. In the cytoplasm, most of the CpG ODNs were localized in lysosome, and some of them escaped from the lysosomal compartments and aggregated around the nuclear. The results clearly demonstrated that CpG ODNs could be internalized directly by crab haemocytes and mostly located in the late endosome. The enhancements of immuno-protection efficiency and growth rate from CpG ODNs as supplements in diets might depend on the uptaking and locating processes, and they could be used as a potential immunostimulant for the crab aquaculture.
