Induction of antigen-specific IgG subclasses and cytokines by FomA. OVA-specific IgG subclasses measured in the sera of wt mice (A) and TLR2 KO mice (B) immunized with OVA alone or OVA-FomA by ELISA normalized to preimmune sera and expressed as mean titers ± SD. *, P = 0.03; ***, P = 0.0002. Sera were used at a 1:100 dilution. (C) Cytokine levels in sera from wt mice immunized with OVA alone or OVA-FomA measured by ELISA. The values were normalized to pooled preimmune sera and expressed as fold change ± SD. *, P = 0.015.
