From: M cell targeting by a Claudin 4 targeting peptide can enhance mucosal IgA responses
Persistence of response to recombinant protein vaccine, four dose protocol. After an initial four week course of immunization, mice were rested for ten weeks for later assay. Results showed persistence of both the antibody response and evidence for enhanced IgA response when CPE targeting was used. A, Immunization protocol. B, Response 4 weeks after first dose. C, Response 14 weeks after first dose.
