Research Abstract

1.CHP(cholesterol hydrophobized pullulan)は、プルラン鎖に、コレステロールを配したナノパーティクルである。CHPとNY-ESO-1蛋白の複合体をDCにパルスし、健常人から得たCD8T細胞をin vitroで刺激し、特異的な反応の誘導を検討した。2回以上の刺激で特異的CD8T細胞の反応が認められた。同じ、CHP-NY-ESO-1複合体パルスDCを用いてCD4T細胞を刺激して、同様に特異的に反応が誘導されるか否かを検討した。やはり、2回以上の刺激でCD4T細胞の反応が誘導された。オーバーラップペプチドを用いて、DR1501拘束性の新しいエピトープを同定した。このように、DC細胞は、CHP-NY-ESO-1複合体を取り込んで、クラスIおよびIIのいずれのエピトープも発現することを明らかにした。
2.CHP-NY-ESO-1を用いた臨床試験を開始した。臨床試験プロトコルは、ニューヨーク、ラドウィック癌研究所および岡山大学大学院医歯学総合研究科で承認された。第一目的は、安全性およびNY-ESO-1に対する免疫能の検討で、第二目的は、腫瘍の反応を観察することである。2週おきに4回投与する。他に有効な治療法がない進行癌患者を対象とする。現在、参加登録患者は4名で、その内訳は、食道癌(IV期)1名、および前立腺癌(D期)3名である。現在、評価可能患者数は3名であるが、3名ともに強い抗体産生が認められた。抗体認識エピトープの解析では、特に抗原性の強いエピトープが認められた。CD8およびCD4T細胞の反応は、比較的早くから認められた。腫瘍に対してもある程度の効果を認めた。
