Outline of Annual Research Achievements

強力な抗腫瘍免疫応答の誘導は腫瘍克服に繋がる重要なテーマである。抗がん剤治療時には大量の細胞死した腫瘍細胞が供給されるため、腫瘍内浸潤樹状細胞(DC)の細胞死した腫瘍の貪食をはじめ、所属リンパ節における抗原特異的CD8+T細胞との相互作用は大きく変化すると考えられる。従って、その解明は抗がん剤治療時における抗腫瘍免疫誘導を考える上で重要である。そこで本研究は、腫瘍細胞死誘導時における、腫瘍内浸潤DCの腫瘍細胞貪食、所属リンパ節への移行、そして、DCと抗原特異的CD8+T細胞の所属リンパ節における相互作用をreal time可視化により明らかにすることを目的とした。
腫瘍内に浸潤したDCを赤色にマーキングすることで、腫瘍から所属リンパ節に移行した腫瘍浸潤DCを追跡・可視化出来る、紫光により緑から赤色に変色する光変換蛍光タンパク質KikGRを樹状細胞系列特異的に発現するマウスに、蛍光タンパク質tdKeima、モデル抗原、および細胞死誘導のためにDiphtheria toxin-receptorを発現させた腫瘍細胞株を移植して用いた。
腫瘍細胞内には沢山のKikGR陽性DCが観察されたが、腫瘍の貪食は殆ど認められなかった。しかし、腫瘍細胞死を誘導すると、殆どの腫瘍内浸潤DCが腫瘍細胞を貪食し、腫瘍浸潤DCの所属リンパ節への移行も増加した。そして、腫瘍から所属リンパ節に移行した赤色にマーキングしたDCと抗原特異的CD8+T細胞の相互作用も観察された。そこでさらに、腫瘍細胞死の誘導とともにDCの成熟を促進するLPSを腫瘍内に投与すると抗原特異的CD8+T細胞の増殖促進が認められた。以上の結果から、抗がん剤治療時に腫瘍内浸潤DCの成熟促進を組み合わせることにより、より強い抗腫瘍免疫応答を誘導できる可能性が示された。
