英文原题：NK cells link immune-checkpoint blockade immunotherapy and response in melanoma brain metastases.
本研究表明，ICB 可触发 NK 细胞趋化因子释放、CD8 T 细胞募集以及抗肿瘤免疫增强。
黑色素瘤脑转移（BM）是重大临床挑战。本文评述免疫检查点阻断（ICB）治疗黑色素瘤脑转移的作用机制新认识，特别关注 Fife 等人近期研究揭示的自然杀伤（NK）细胞在 ICB 治疗后塑造肿瘤微环境中的非经典作用。该研究显示，NK 细胞并非直接杀伤肿瘤细胞；相反，ICB 会触发 NK 细胞释放趋化因子，募集 CD8 T 细胞并增强抗肿瘤免疫。研究结果表明，ICB 的作用机制十分复杂，其影响超越了细胞毒性 CD8 T 细胞与肿瘤细胞之间抑制性受体-配体相互作用的直接阻断。
Melanoma brain metastases (BMs) pose a significant clinical challenge. This commentary highlights the emerging understanding of the mechanisms behind immune-checkpoint blockade (ICB) efficacy in melanoma BMs. Specifically, we focus on a recent study by Fife et al , which revealed a non-canonical role for natural killer (NK) cells in shaping the tumor microenvironment following ICB therapy against melanoma BMs. Instead of direct tumor cell killing, this study demonstrates that ICB triggers NK cell chemokine release, CD8 T cell recruitment and enhanced antitumor immunity. The findings from this study highlight that the ICB mechanisms of action are complex and extend beyond the direct interference of inhibitor receptor-ligand interactions between cytotoxic CD8 T cells and tumor cells.
