| Outline of Final Research Achievements |
RNA regulatory molecule TFL is discovered in a chromosomal aberration in lymphomas, and TFL-/- mice are created. TFL-/- mice were bred to lymphoma model mice to investigate the relationship between TFL-/-. Cachexia due to enhanced inflammation was observed in the TFL-deficient mice. We also observed an increase in the chemokine CXCL-13 and a significant decrease in their body weight in correlation with the time of tumor onset. The results showed a trend toward a better prognosis in the TFL-deficient group. In the future, we will reexamine immunostaining and expand the target to other lymphomas.

| Academic Significance and Societal Importance of the Research Achievements |
TFLは免疫調節という重要な分野ににも関わらずあまり研究されて来なかった。近年、少しづつTFLに関わる報告が増えてきており、いずれも免疫、腫瘍の分野で重要な働きをしていることを示唆するものである。今回我々はマウスのデータを論文発表において、TFLが免疫調節を制御しながら腫瘍のあるマウスの体重減少に関与したことを示した。今後、ますますこの分子の研究が盛んになっていくものと思われる。近い将来TFLが何らかの腫瘍、自己免疫疾患のマーカーとして用いられると考えられる。
