Outline of Research at the Start

細胞傷害性T細胞の細胞傷害活性には不均一性が存在し、標的細胞との接触は必ずしも殺傷に繋がらない。がん免疫細胞療法時に殺傷能の高いT細胞を選択投与できれば、副作用低減・治療効果向上に繋がると期待される。しかし殺傷能の規定機構は未解明である。本研究では、細胞傷害性顆粒放出に必須とされるキナーゼ、細胞外シグナル調節キナーゼ(ERK)の活性動態に着目する。ERK活性動態の制御機構を解明することで、殺傷能の不均一性を規定する機構を解明する。さらに、得られた知見に基づき遺伝子改変T細胞療法を始めとするがん免疫細胞療法研究目的の治療効果向上へと貢献する。

Outline of Annual Research Achievements

2021年4月より研究環境を米国へ移して以降は、血液悪性腫瘍の一つ、多発性骨髄腫の病期進展における腫瘍微小環境の果たす役割に着目し研究を展開している。多発性骨髄腫は原則として前がん病態である意義不明の単クローン性免疫グロブリン血症(MGUS)及びくすぶり型骨髄腫(SMM)から進展する。多発性骨髄腫で認められる染色体異常や遺伝子異常は、前がん状態であるMGUSやSMM段階の骨髄腫細胞においても既に認められることが知られている。しかし、興味深いことに、多くの患者はMGUSおよびSMMから多発性骨髄腫へと病期が進行することなく経過する。従って、腫瘍細胞側のみでなく、腫瘍微小環境側の因子が多発性骨髄腫病期進展の重要な因子となっていることが想定される。
MGUS及びSMMの患者骨髄において、健常人骨髄と比較して免疫細胞の機能や細胞ごとの比率に変化が認められることは以前より報告されていた。これを踏まえ、SARS-CoV-2ワクチン接種に対する免疫応答を、抗体価を測定することで評価し、この骨髄微小環境で認められる免疫異常が実際に患者の免疫応答不全に繋がることを明らかにした。またシングルセルRNAシーケンスおよびプロテオミクス解析を用いて細胞免疫応答も含めた免疫応答解析を展開し、前がん状態患者において、長期免疫応答の維持機構に破綻が生じていることを見出した。具体的には、ワクチン接種初期の抗体価は健常人と同等であるにも関わらず、4ヶ月を過ぎた頃より健常人と比較して抗体価の低下が認められた。またT細胞免疫応答についても、ワクチン接種初期には健常人と同様に、抗原に応答するT細胞受容体を有するT細胞クローンの増多が確認された。4ヶ月を過ぎる時期というのは、別途報告されたMGUS/SMM患者におけるブレークスルー感染が健常人と比較して有意に上昇する時期と合致する。
今後は、この臨床上重要な転機につながる長期免疫応答維持機構の破綻メカニズムについて解析を加えていく。
