Outline of Final Research Achievements

Approximately 10-20 million of Human T-cell leukemia virus type-1 (HTLV-1)-infected carriers have been previously reported, and approximately 5% of these carriers develop adult T-cell leukemia/lymphoma (ATLL) with a characteristic poor prognosis. It is unknown why HTLV-1 causes ATLL and why HTLV-1/EBV co-infected B-cell lines are frequently established from ATLL patients. To elucidate the mechanism of ATLL development and characterize the HTLV-1/EBV co-infected B-cell lines, we performed a comprehensive analysis of HTLV-1 mutations and integration sites using approximately 700 specimens obtained from asymptomatic carriers,HAM/TSP patients, and ATLL patients. These analysis demonstrated a finding of ATLL specific HTLV-1 mutations and the usefulness of monitoring HTLV-1 clonality for ATLL risk assessment.

Academic Significance and Societal Importance of the Research Achievements

本研究計画の一つである網羅的HTLV-1挿入部位解析を実施するために、RAISING(Rapid Amplification of Integration Site without Interference by Genomic DNA contamination)法を株式会社ファスマックと共同開発した。本技術は、現在ATLL確定診断に用いられているサザンブロット法より簡便、迅速、低コストかつ高精度であるため、今後のATLL早期診断法としての応用が期待される。
