複数のゴールへの「複数回のシュート」：武装不変NK細胞アプローチ

Adoptive T-cell therapies have shown limited efficacy against solid tumors, so new approaches are required. In this issue, Chantzoura and colleagues describe MiNK-215, a novel allogeneic fibroblast activation protein-targeting chimeric antigen receptor invariant NK T-cell therapy engineered to secrete IL15. They show that it can remodel the tumor microenvironment and enhance antitumor immunity by depleting fibroblast activation protein-positive cancer-associated fibroblasts and activating multiple immune cell types. In mouse lung tumor and human organoid models, MiNK-215 promotes durable, antigen-specific T-cell responses and overcomes resistance to immunotherapy without causing off-target toxicity.
