| 摘要 | Heat shock protein (Hsp) 70 is a molecular chaperone that plays an important role in protein folding and transport. In addition, Hsp70 is also involved in regulation of innate and adaptive immune response. In this study, we examined the biological activity and the immunomodulatory property of an Hsp70 homologue, PoHsp70, from Japanese flounder (Paralichthys olivaceus). Recombinant PoHsp70 purified from Escherichia coli exhibits apparent ATPase activity; however, a mutant PoHsp70, PoHsp70M, that bears mutation of the ATPase-associated domain, was completely abolished in activity. Expression of PoHsp70 was upregulated in a time-dependent manner by vaccination of flounder with a DNA vaccine, pSia10. that expresses a Streptococcus iniae antigen, Sia10. To examine whether PoHsp70 possessed any adjuvant potential, the DNA vaccine plasmids pSia10Hsp70 and pSia10Hsp70M were constructed. pSia10Hsp70 co-expresses Sia10 and PoHsp70, while pSia10Hsp70M co-expresses Sia10 and PoHsp70M. Following vaccination of flounder, production of Sia10 plus PoHsp70 and Sia10 plus PoHsp70M was detected in pSia10Hsp70- and pSia10Hsp70M-vaccinated fish respectively. At one month post-vaccination, comparable levels of serum antibodies were detected in fish vaccinated with pSia10Hsp70, pSia10Hsp70M, and pSia10. Subsequent protection analysis showed that, followings. iniae challenge, pSia10Hsp70 induced a survival rate that was significantly higher than that induced by pSia10, while pSia10Hsp70M induced a survival rate similar to that induced by pSia10. These results indicate that PoHsp70 is an effective adjuvant and that the adjuvanticity of PoHsp70 requires the intrinsic ATPase activity. (C) 2012 Elsevier Ltd. All rights reserved. |
