FIG 7.

Antigen-specific IgA antibodies detected after oral immunization by ELISA. Fecal samples were collected from mice on the termination day and pooled within each group (4 mice per group). (A) Detection of antigen-specific IgA in the different groups using recombinant AgE6 protein. The results are presented as means of at least three independent measurements of OD₄₀₅ ± SEMs. *, P <0.05. (B) Values for groups immunized with Lp_Ev, Lp_1261AgE-DC, or Lp_DC-AgEcwa2 after normalization by total IgA (based on the OD values). The results represent the ratios of antigen-specific IgA versus total IgA and are presented as a mean of duplicates ± SEMs.
