| Outline of Annual Research Achievements |
本研究の目的は、抗PD-1抗体で治療された各種がんにおいて、① 末梢血のB細胞受容体（BCR）レパトア解析の臨床的意義（特に、治療効果・有害事象合併を予測するバイオマーカーとしての有用性）、② 有効例あるいは有害事象合併例において選択的に増殖するB細胞クローンの認識する抗原の同定と作用メカニズム（抗腫瘍効果、自己免疫反応）との関連、を明らかとすることである。本研究の成果は、抗PD-1抗体の作用メカニズムを解明するとともに、不必要な治療による不利益（有害事象合併・医療費浪費）の回避につながると期待される。
本年度には、① 抗PD-1抗体で治療された進行尿路上皮がん患者20例の治療開始前後に採取した末梢血単核球におけるBCR配列を決定し、前年度に測定した尿路上皮がん患者10例でのデータと合わせて統計学的に解析した。BCRレパトア多様性を治療前後で比較したところ、有害事象を合併した患者では治療後のBCRレパトア多様性が有意に減少した。ただし、治療後のBCRレパトア多様性の変化と治療効果との間には有意な相関を認めなかった。また、治療後のT細胞受容体（TCR）レパトア多様性の変化と治療効果・有害事象合併との間にも有意な相関を認めなかった。これまでの結果を総合すると、抗PD-1抗体治療後のBCRレパトア多様性の変化は進行非小細胞がん患者では治療効果と相関し、進行尿路上皮がん患者では有害事象合併と相関するものと示唆された。② BCR遺伝子解析の結果から、有害事象合併例の治療後に選択的に増加したB細胞クローンに由来するBCR（IgG H鎖およびL鎖）の遺伝子配列を同定し、精製抗体を作成した。現在、精製抗体の各種ヒト細胞株・組織に対する反応性を検討し、認識抗原を同定中である。
