Outline of Final Research Achievements

The lack of appropriate model has been a concern in dengue research pertinent to immune response. Traditional sources of dendritic cell (DC) which is essential for the in vitro experiments, mostly monocyte derived DC (moDC), have been used despite their limitations such as quantity and donor dependent characters. Development of human iPS cell with consistent proliferation, stable characteristics and desired background has offered added advantages. Therefore, we hypothesized that iPS cell would be a reliable alternative source of DC for in vitro system for dengue virus (DENV). To develop DENV infection and T cell activation model, we utilized iPS cell derived DC line (iPS-DC). DENV infection sensitivity of our iPS-DC was similar to that of moDC. Moreover, iPS-DC had the ability to activate HLA-matched T cell. This affirmed the antigen-specific T cell activation by iPS-DC as a function of antigen presenting cell. Now we are in preparation for further development of this system.

Academic Significance and Societal Importance of the Research Achievements

デングウイルス(DENV)感染症における細胞性免疫(T細胞を中心とした免疫反応)の働きは、更なる解明が求められている。樹状細胞(DC)はこの解析に必須の細胞であり、これまでは「限られた細胞数」「実験毎の細胞の性質のばらつき」「細胞の性質のドナーへの依存」などの問題を持つヒト末梢血由来のものが主に使用されてきた。我々はこれらの問題を解決するため、iPS細胞由来DCを用いた実験系を構築し、DENV特異的なT細胞活性化に成功した。DENVは正常マウスに感染できず動物実験にも限界が有るため、我々の実験系は(まだ改良の余地はあるが)免疫学的解析を中心としたデング熱研究の発展に貢献可能であると考えている。
