Figure 7From: Oral vaccination with Trichinella spiralis DNase II DNA vaccine delivered by attenuated Salmonella induces a protective immunity in BALB/c miceIFN-γ, IL-10, and IL-4 upon rTsDNase II stimulation were assayed by ELISA. Concentration of cytokines in spleen (A) and MLN (B) cell supernatant was detected following stimulation with rTsDNase II for 72 h. Data is presented as mean ± SD of cytokine concentrations (n = 5). Asterisk represents an evident difference between two groups (P < 0.01).Back to article page
