pubmed:abstractText |
The capacity of Shigella flexneri to act as a delivery system for stimulation of local immunity was investigated by use of an S. Flexneri 2a vaccine candidate (SC602). This vaccine strain was constructed by deletion of virulence genes responsible for dissemination (icsA) and survival (iuc:iut) of bacteria within the colonic mucosa. Among the most immunogenic S. flexneri 2a proteins inducing a local immunoglobulin A antibody response, the IpaC invasion was selected as a potential protein carrier. Overexpression of IpaC from a plasmid in trans within SC602 (SC602/pIpaC) was shown to be required for the induction of optimal anti-IpaC antibody response in the murine pulmonary infection model. A weak anti-IpaC antibody response was obtained after intranasal inoculations with SC602/pIpaC live bacteria. This response was enhanced by combining systemic priming with SC602/pIpaC killed bacteria and local boosting with SC602/pIpaC live bacteria. These results suggest that naive B cells primed systemically could account for local antibody production. This immunization protocol will allow further evaluation of the immunogenicity of IpaC hybrid proteins expresses in SC602.
