Outline of Final Research Achievements |
Recent research revealed that 50 genes are significantly mutated in ATLL. In this study, we sequentially performed targeted sequencing of the 50 genes on peripheral blood CD4 positive T-cells among 30 HTLV-1 carriers. Only in one carrier, a few mutations were confirmed at the first sequencing. During the follow up, the carrier with mutations developed ATLL, while other carriers did not. Unexpectedly, sequential sequencings of the carrier who developed ATLL revealed that mutations were different between the first and the following sequencing, suggesting that ATLL does not necessarily develops from the major clone at the time of carrier. The elucidation of the mechanism of the clonal selection is expected.
