Objective: Transcutaneous immunization (TCI) is a novel route of vaccination through application of a topical vaccine antigen on the skin. Phosphorylcholine (PC) is a structural component of a variety of pathogens and anti-PC immune responses protect mice against invasive bacterial diseases. The purpose of the study was to examine the effect of TCI using PC in BALB/c mice.Methods: TCI was performed in BALB/c mice using PC–keyhole limpet hemocyanin (KLH) plus cholera toxin (CT). Immunogenicity was evaluated by measuring PC-specific IgG and specific IgG1, IgG2a, IgM, IgA, and secretory IgA antibodies by ELISA. The concentrations of IL-4, IL-5, IL-10, IL-12, IL-13 and IFN-γ were also measured using ELISA for mouse.Results: Six months after immunization, IgG after TCI using PC plus CT was significantly higher than in controls, but this was not found for IgA. In saliva, secretory IgA antibodies decreased with a peak level at 2–3 months. IgG1 was significantly higher than IgG2 after TCI. Production of IL-4 from CD4+ cells was significantly higher after TCI than in controls, whereas production of IFN-γ, IL-5, IL-12 and IL-13 was not detected in either group.Conclusion: These results suggest that TCI using PC plus CT with BALB/c mice is a simple approach for induction of systemic and mucosal immune responses that are shifted in the Th-2 direction.
