| Research Abstract |
Dendritic cells (DCs) are essential for the induction of antigen (Ag)-specific immune responses, DC-targeted vaccination might be an effective strategy for the induction of the specific immune responses. A DNA plasmid encoding the P6 outer membrane protein of nontypeable Haemophilus influenzae (NTHi) was constructed. Mice were immunized 3 times intranasally with the DNA plasmid and Matrix-M, an immunostimulatory complex adjuvant. P6-specific nasal wash IgA and serum IgG were elevated following immunization with the DNA plasmid and Matrix-M. The number of specific IgA-producing cells increased in the nasal passages of the immunized mice. Moreover, DNA vaccination enhanced bacterial clearance. These findings suggest that a successful DNA vaccination protocol has been developed. Nasal vaccination with P6 DNA vaccine and Matrix-M might be a new effective regimen for the induction of specific protective immunity in the upper respiratory tract.
