Outline of Research at the Start

抑制性の免疫補助受容体であるPD-1とCTLA-4を標的としたがん免疫療法が多様な種類のがんに対して劇的な治療効果を示したことから、免疫補助受容体が大きな関心を集めている。PD-1は自己免疫やがん免疫を効率的に抑制するが、通常の感染免疫を無力化することは無い。本研究では、独自に作製した遺伝子改変マウスを用いた免疫学的解析により、PD-1が有益な免疫応答を無力化しないメカニズムの解明を試みる。

Outline of Final Research Achievements

We found that CD80 interacts with PD-L1 in cis on antigen presenting cells (APCs), which results in the interference of PD-L1-PD-1 binding. Subsequently, PD-L1 fails to elicit PD-1-mediated inhibition in T cell activation when APCs express substantial amount of CD80. By generating anti-CD80 antibodies that detach CD80 from the cis-PD-L1-CD80 duplex and enable PD-L1 to engage PD-1 in the presence of CD80, we demonstrated that the targeted dissociation of cis-PD-L1-CD80 duplex elicits PD-1 function in the condition where PD-1 function is otherwise restricted. We also demonstrated using murine models that the removal of PD-1 restriction is effective in alleviating autoimmune disease symptoms. Finally, we investigated the relative contribution of potential ligands to LAG-3 function and demonstrated that stable pMHCII, but not FGL1, serves as the functional ligand of LAG-3 to trigger its immuno-inhibitory function.

Academic Significance and Societal Importance of the Research Achievements

抑制性免疫補助受容体PD-1を標的としたがん免疫療法の成功により、免疫補助受容体の機能が大きな関心を集めているが、各分子の機能解明は期待通りには進んでいない。PD-1やLAG-3の機能が発揮あるいは制限されるメカニズムの解明により、これらの分子を標的とした薬剤の開発が促進されると期待される。PD-1の機能制限を解除することにより自己免疫疾患を治療する方法については、臨床への応用が期待される。
