Objective:To investigate the changes of splenocyte cytokines in mice induced by recombinant BCG-Em14-3-3 vaccine of Echinococcus multilocularis(Em) and challenge with Em protoscoleces.Methods:BALB/c mice were subcutaneously and intranasally vaccinated respectively
then challenged with Em protoscoleces at 8th week of vaccination and killed at 18th week of infection to get spleen.Splenocytes were separated to culture by stimulation with EmAg or ConA.The supernatants were collected to measure IL-2、IFN-γ、TNF-αand IL-4 by ELISA Kits
and blank vector
BCG and PBS served as control.Results:In the groups of immunization
levels of IFN-γand TNF-α increased
but that of IL-4 decreased.The level of TNF-α in the intranasal group was higher than that in the subcutaneous group.Conclusion:TH1 response is induced in mice by rBCG-Em14-3-3 vaccine which is against the challenge of Em protoscoleces.
