pubmed-article:21262813 | pubmed:abstractText | Improved protein-based vaccines should facilitate the goal of effective vaccines against HIV and other pathogens. With respect to T cells, the efficiency of immunization, or "immunogenicity," is improved by targeting vaccine proteins to maturing dendritic cells (DCs) within mAbs to DC receptors. Here, we compared the capacity of Langerin/CD207, DEC205/CD205, and Clec9A receptors, each expressed on the CD8(+) DC subset in mice, to bring about immunization of microbial-specific T cells from the polyclonal repertoire, using HIV gag-p24 protein as an antigen. ?-Langerin mAb targeted splenic CD8(+) DCs selectively in vivo, whereas ?-DEC205 and ?-Clec9A mAbs targeted additional cell types. When the mAb heavy chains were engineered to express gag-p24, the ?-Langerin, ?-DEC205, and ?-Clec9A fusion mAbs given along with a maturation stimulus induced comparable levels of gag-specific T helper 1 (Th1) and CD8(+) T cells in BALB/c × C57BL/6 F1 mice. These immune T cells were more numerous than targeting the CD8(-) DC subset with ?-DCIR2-gag-p24. In an in vivo assay in which gag-primed T cells were used to report the early stages of T-cell responses, ?-Langerin, ?-DEC205, and ?-Clec9A also mediated cross-presentation to primed CD8(+) T cells if, in parallel to antigen uptake, the DCs were stimulated with ?-CD40. ?-Langerin, ?-DEC205, and ?-Clec9A targeting greatly enhanced T-cell immunization relative to nonbinding control mAb or nontargeted HIV gag-p24 protein. Therefore, when the appropriate subset of DCs is targeted with a vaccine protein, several different receptors expressed by that subset are able to initiate combined Th1 and CD8(+) immunity. | lld:pubmed |
