1) キャリア
2002年に岡山大学を卒業後、研修医として虎の門病院でご指導頂き、2007年から血液内科医員に採用頂きました。2009年に千葉大学大学院に入学し、横浜の理化学研究所(理研)で研究に従事させて頂きました。理研では石川文彦博士のご指導のもと、ヒト化マウス(免疫不全マウスにヒト造血を再構築したもの)を用いて白血病幹細胞や骨髄微小環境の研究を行いました。2012年に大学院を卒業し、2013年から分院、2014年から本院の血液内科医員として再び虎の門病院で血液内科診療を行う機会を与えて頂いています。
2) 研究分野
2003年から赴任した谷口修一部長をはじめとした多くの先輩方のご尽力により臍帯血移植が普及し、その恩恵を受ける重症患者さんたちを研修医として眼の当たりにしました。その時に受けた衝撃が純粋に単純に現在の私の血液内科診療に対する情熱を灯し続けています。現在は、臍帯血移植やその後の合併症に加えて造血器疾患の発症から治癒までを幅広く、臨床医学と医科学の両方の視点から研究対象としています。また、共同研究を通して理研とも継続的に繋がっており、理研と虎の門病院、そして当研究所が組むユニークかつ強力なタッグが造血器疾患の治療に大きな風穴を開ける日もそう遠くないと信じています。
造血器疾患
・白血病幹細胞が急性骨髄性白血病の治療に与える影響について
・原発性および二次性骨髄線維症に対する同種造血細胞移植について
・急性混合性白血病に対する同種造血細胞移植について
・慢性骨髄性白血病に対する臍帯血移植について
・急性骨髄性白血病に対する新規標的療法の開発について(理研との共同研究)
移植療法
・臍帯血に含まれるCD34 細胞数と臍帯血移植後の生着について
・高齢者に対する新たな臍帯血移植の前処置の開発について
・臍帯血移植後の血球貪食症候群について
・臍帯血移植後の早期免疫合併症とそれらの至適制御方法の開発について
・同種造血細胞移植後の血流感染について
・同種造血細胞移植後の類洞閉塞症候群と凝固異常について
・同種造血細胞移植後の末梢神経合併症について
・同種造血細胞移植後の抗真菌薬の体内動態について
3) 今後の抱負・アピール
様々な領域に課題を見出し同時進行で研究を進めています。これら一つ一つは虎の門病院での臨床と理研での研究における私自身の実体験に基づいた疑問や苦悩であり、克服すべき課題ばかりです。志を同じくする仲間たちと共に新しい知見を見出し、世界に発信していきたいと思います。研究から臨床へ、臨床から研究へ、両輪の架け橋になりながら、それらがそれぞれに大きく実り、力強い進歩が患者さんの元へ届くことで社会に還元できるよう今後も精進致します。
