We investigated the kinetics of humoral immunity and its related cellular immune responses to intranasal (IN) immunization with a detoxified lipooligosaccharide (dLOS)-tetanus toxoid (TT) conjugate against nontypeable Haemophilus influenzae (NTHi) in mice. IN vaccination with dLOS-TT elicited high titers of LOS-specific IgA in nasal washes and IgG in sera during a course of 4 inoculations while high titers of TT-specific IgA and IgG were found in sera. A significant increase of LOS-specific IgA antibody forming cells (AFCs) was observed in nasopharyngeal-associated lymphoid tissue (NALT) and nasal passages. However, TT induced broad responses with higher numbers of IgA and IgG AFCs found in NALT and nasal passages, less but significant IgA AFCs in cervical lymphoid nodes (CLN), spleen, and lungs. Phenotypic analysis revealed a significant rise of total B220+ B-lymphocytes in NALT and CLN, particularly a rise in IgA+/IgM+ cells in the NALT after the immunization. The latter result was complied with a significant rise of IL-4 but not IFN-gamma positive CD4+ T-lymphocytes in NALT. Analysis of IgG antibody subclasses showed that an IgG1 response to both LOS and TT epitopes dominated in serum when compared to IgG2a. These kinetic antibody patterns and cellular responses may provide useful information regarding to effective mucosal vaccines against NTHi infections.
