2018 Fiscal Year Annual Research Report

• Project/Area Number: 18J02173
• Research Institution: National Institute of Infectious Diseases
• Principal Investigator: 朝倉 崇徳 国立感染症研究所, ハンセン病研究センター感染制御部, 特別研究員(PD)
• Project Period (FY): 2018-04-25 – 2021-03-31
• Keywords: 肺非結核性抗酸菌症 / NTM / 肺MAC症 / 気管支拡張症

Outline of Annual Research Achievements

共同研究で実施されている、肺NTM症に関するゲノムワイド関連解析において候補SNPおよび疾患感受性遺伝子Xが同定された。肺NTM症の疾患感受性遺伝子Xが恒常的に検出されていることがデータベースで確認されている、ヒト上皮細胞株H292細胞株に対して、Mycobacterium avium subsp. Hominissuis (MAH)104株を感染させ、菌の細胞内への取り込みおよびその後の細胞内増殖の変化、疾患感受性遺伝子Xの変動を経時的に確認した。菌に関しては培養およびチールニールゼン染色で評価した。その後同様の実験をsiRNAによるknockdown(KD)、プラスミドによるoverexpression(OE)を試み施行した。それぞれの遺伝子のKDおよびOEは確認したものの、菌量および遺伝子発現の明確な差は検出できなかった。同様の実験をヒト気道上皮株であるBEAS2Bで施行したが、同様に明確な差が得られなかった。ヒト末梢血単核球細胞(PBMC)に対する経時的な感染実験においても候補遺伝子をいくつか検討したが、明確な上昇を得ることはできなかった。
肺NTM症および気管支拡張症の検体に関しては、今後はさらに検体集積機関を増やし集積していく予定である。

Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

In vitroの実験に関して、いくつか細胞株を用いたモデルを中心に試み、遺伝子改変自体は行えていることを確認したが菌の感染によるphenotypeの差を明確にすることはできなかった。

Strategy for Future Research Activity

現在のモデルにおいて、in vitroの実験は上手く行っておらず、NTMがどのような感染形式で肺に感染するか、ヒト検体を用いてに着目し解析を進めていくことを予定している。
