[Experimental study on immunization of mice with nucleic acid vaccine Sj31BIN combining IL-12 against Schistosoma japonicum].
Based on the anti-fecundity effect of Schistosoma japonicum nucleic acid vaccine Sj31BIN, we combined Sj31BIN with IL-12 in vaccination of mice to explore the role of IL-12 as an adjuvant. The result showed that immunization of the mice with Sj31BIN + IL-12 led to a significant decrease in adult worm recovery, a liver egg count reduction of 59.74%, an intestine egg count reduction of 59.60% and a liver surface egg granuloma reduction of 71.3%. In addition, vaccination of the mice with IL-12 alone also led to some but not significant decrease in adult worm recovery and the egg counts. It is concluded that Sj31BIN plus IL-12 induces significant anti-fecundity immunity.
