Outline of Annual Research Achievements

がん化学療法中患者において院内感染やアウトブレイクがどのように伝播するかを確認するために、当科で経験したESBL耐性遺伝子伝播による複数菌種のアウトブレイクについて分子微生物学的に解析した。その結果病棟内アウトブレイクだけでも、クローナルアウトブレイクと非クローナルアウトブレイクがあることが分かった。
次に、がん化学療法中患者の骨髄液や末梢血からγδ細胞を抽出してそのγδ細胞の細胞生物学的な特徴を確認した。実臨床に用いるレベルでのγδ細胞の誘導は困難であったことから、初発時のγδ細胞の量とその後の臨床的アウトカムを、2012年からの血液疾患症例を用いて前向きに検討した。
さらに本年度において腸管内細菌叢のメタゲノム解析を行い、プレバイオティクスとプロバイオティクスが腸管免疫や宿主免疫に与える影響を解析する予定である。

Current Status of Research Progress
Current Status of Research Progress

3: Progress in research has been slightly delayed.

Reason

当初予定したγδ細胞の増力がみられず、体内での内因性γδ細胞と患者治療アウトカムとの関連を調べることとした。

Strategy for Future Research Activity

本年度において腸管内細菌叢のメタゲノム解析を行い、プレバイオティクスとプロバイオティクスが腸管免疫や宿主免疫に与える影響を解析する予定である。

Causes of Carryover

最終年度の研究を実施するため。

Expenditure Plan for Carryover Budget

血液腫瘍性疾患患者のγδT細胞の解析に使用する。
