            <strong>Smart NK</strong>（智能型自然杀伤细胞）是指通过 <strong>[[基因工程]]</strong> 或化学修饰，使其具备逻辑识别、微环境重塑及长效存续能力的新一代 <strong>[[NK 细胞]]</strong> 药物。与第一代 <strong>[[CAR-NK]]</strong> 相比，Smart NK 不再局限于单一抗原的识别，而是集成了 <strong>[[逻辑门 (Logic Gates)]]</strong> 系统（如 AND/OR/NOT 门）、细胞因子自分泌回路以及抑制性受体（如 <strong>[[NKG2A]]</strong>/<strong>[[TIGIT]]</strong>）的基因屏蔽技术。2026 年的临床数据表明，Smart NK 在处理 <strong>[[实体瘤]]</strong> 异质性和克服肿瘤微环境（TME）代谢抑制方面展现出显著优势，成为“通用型（Off-the-shelf）”细胞免疫治疗的重要里程碑。
