Figure 4From: PCEP enhances IgA mucosal immune responses in mice following different immunization routes with influenza virus antigensEnhanced IgA and IgG titers from immunized mice are also found in vaginal secretions. Vaginal mucosal washes were also collected at the end of the 8 week experiment where X:31-specific IgA (A) and IgG (B) was assayed from mice that were immunized by IN, SC, oral, or IR immunization with either PCEP+X:31 (closed bars) or X:31 alone (open bars). Different letters indicate significant differences between groups that received PCEP+X:31, while asterisks indicate significant differences between PCEP+X:31 compared to X:31 antigen alone (p < 0.05).Back to article page
