Research Abstract |
The aim of this research is to clarify mechanism of a novel signal polypeptide (N'-CARD-PTD)-induced innate immune activation and adjuvanticity of N'-CARD-PTD. Previous research we identified histone H2B is involved in dsDNA-mediated innate immune activation. Recently we synthesized the newly fusion protein, N'-CARD (nuclear localization signal of H2B fused CARD of IPS-1), activated nuclear DNA helicase II (NDH)-mediated innate immune responses. In this research, we clarify that protein transduction domain fused N'-CARD (N'-CARD-PTD) activated dendritic cells depend on type I IFN, but not TLRs. As a vaccine adjuvant, N'-CARD-PTD strongly induced antigen specific antibody response against various antigen.
