Abstract
It is of great interest to develop a pneumonic plague vaccine that would induce combined humoral and cellular immunity in the lung. Here we investigate a novel approach based on targeting of dendritic cells using the DEC-205/CD205 receptor (DEC) via the intranasal route as way to improve mucosal cellular immunity to the vaccine. Intranasal administration of Yersinia pestis LcrV (V) protein fused to anti-DEC antibody together with poly IC as an adjuvant induced high frequencies of IFN-γ secreting CD4+ T cells in the airway and lung as well as pulmonary IgG and IgA antibodies. Anti-DEC:LcrV was more efficient to induce IFN-γ/TNF-α/IL-2 secreting polyfunctional CD4+ T cells when compared to non-targeted soluble protein vaccine. In addition, the intranasal route of immunization with anti-DEC:LcrV was associated with improved survival upon pulmonary challenge with the virulent CO92 Y. pestis. Taken together, these data indicate that targeting dendritic cells via the mucosal route is a potential new avenue for the development of a mucosal vaccine against pneumonic plague.
