Abstract
To study the immunomodulation effect of the recombination Sj16 from Schistosoma japonicum (reSj16) on inflammation response of host. reSj16 expressed in pGEX-4T-1 was purified by GST purification kit and detected by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and mass spectra (MS). The immunomodulation effect of reSj16 was observed by means of dimethylbenzene inducing mouse ear edema model, carrageenan inducing rat voix pedis swell model and acetic acid inducing mouse experiment peritonitis model. The soluble protein of reSjl6 was obtained and identified by SDS-PAGE and MS. reSjl6 1.0, 5.0, 10.0 microg/kg evidently suppressed the mouse ear edema induced by dimethyl-benzene, significantly mitigated the rat voix pedis swelling induced by carrageenan, and remarkably suppressed the increase of the capillary permeability of abdominal cavity in experiment peritonitis mouse model. The results further prove that Sj16 may be a potential immunosuppressive molecule and may have a notable effect on immunomodulation.
