FIG. 3.
Lung IgG and IgA response. Lung IgG and IgA were determined at week 4 after boost. (A) Lung IgG antibody responses. (B) Lung IgA antibody responses. Results are expressed as averages of optical density readings at 450 nm (OD 450) with 10-fold diluted lung samples in each group of mice (n=6). For lung IgG responses, p<0.05 between VLP alone or V+G or V+P and V+M or V+A(L); p<0.05 between V+M or V+A(L) and V+CT or V+CpG or V+A(H). For lung IgA responses, p<0.05 between VLP alone or V+G or V+P and V+M or V+A(L) or V+CpG or V+CT; p<0.05 between V+M or V+A(L) or V+CpG or V+CT and V+A(H).
