Circulating proinflammatory cytokine levels were measured in serum
samples collected one week post boost immunization and six weeks post M.
avium challenge. (A-H) Concentration of IFN-γ,
TNF-α, IL-1β, IL-2, IL-6, KC/GRO, IL-10, and IL-5 (measured in
pg/mL) at both time points. Bars show mean ± SEM, dots represent
individual mice, n = 3–4/group. Asterisks indicate statistical
significance compared to the saline alone group, where **p<0.01, ***p
< 0.001, and ****p < 0.0001 using two-way ANOVA with
Dunnett’s multiple comparisons test.
