Outline of Research at the Start

慢性活動性EBウイルス感染症 (CAEBV) は進行性、治療抵抗性のEBV陽性T, NK細胞腫瘍であり、発症機構解明と治療薬開発が急務である。EBV由来のマイクロRNAであるmiR-BARTsは、EBV陽性B細胞腫瘍において、宿主細胞の遺伝子発現を制御し不死化を促すとともに、エクソソームに含有され放出されて周囲細胞も制御、発症へ寄与することが報告されている。
本研究ではCAEBVの発症、病態形成におけるmiR-BARTsの機能を解析する。以上はCAEBVの発症機構解明に加え、miR-BARTsを標的とした治療法、診断法、バイオマーカーの開発に寄与し得る。

Outline of Final Research Achievements

Chronic active EBV infection (CAEBV) is a progressive, treatment-resistant EBV-positive T- or NK-cell lymphoma. miR-BARTs, EBV-specific microRNAs, are incorporated into exosomes and translocate to surrounding cells, suggesting their contribution to tumor progression. In this project, we analyzed the expression profiles of secreted miR-BARTs and their functions in CAEBV pathogenesis and pathophysiology. We used CAEBV cell lines and patient plasma for expression profiling and functional analysis experiments. The exosomes incorporated miR-BARTs may contribute to the inflammation and HLH development.

Academic Significance and Societal Importance of the Research Achievements

本研究はCAEBVにおいてEBV由来マイクロRNAの発現とエクソソームの機能に注目した初の研究である。CAEBVの発症患者は平成21年厚労省研究班報告書では年間23.4人と希少疾患とされているが、2015年に診断基準が作成や2017年のWHO分類への記載により国内外で報告数が増えており、潜在的な患者は相当数存在すると推測される。さらに、CAEBV以外にもB細胞腫瘍、上咽頭癌、胃癌など、EBV陽性腫瘍は数多く存在する。これらはすべて難治性であり、本研究の成果は新たな治療法開発に広く応用され得る。
