Outline of Annual Research Achievements

昨年度に続き、症例数の更なる蓄積、および凍結保存細胞試料を用いたmRNA量の解析を進め、びまん性胸膜肥厚(DP)と悪性中皮腫(MM)を比較し、両群間の免疫動態の把握を試みた。細胞表面タンパク質発現量および細胞中mRNAレベルの解析の最終的な結果として、DPに比べ、MMではTh上の①GITR ②CD69発現量が高く、CTL上の③CXCR3 ④CD69発現量は高値であった。Th中の⑤RORC、NK中の⑥c-Rel mRNAレベルはMMで高値であった。他方、DPはTh中の高い⑦GATA-3、CTL中の高い⑧PRF1 (perforin) mRNAレベルを示した。有意差を示す①から⑧を変数とする因子分析(最尤法, 斜交回転)を実施したところ、因子分析は2因子を抽出し、①-⑥は因子1で⑦⑧は因子2で高い因子負荷量(0.4以上)を示した。両因子のスコアを算出し2因子の二次元プロット図を描くと、MM集団は原点から第1象限、第2象限、第3象限に広がる一方、とDP集団は第4象限に集中し、両集団は2因子により明瞭に区別された。以上の結果は、MMとDP間の特にThおよびCTL機能における差異を示す。また、重回帰分析により①②また⑤⑦を独立変数とする数式1および2が算出され、代入により得られるスコア値1および2は良好な ROC曲線を示しMMとDPを明瞭に区別した。それらの結果は免疫学的指標群を用いたMMトDPの判別診断の可能性を示唆する。
