1334-TIGIT靶向型IL-12融合蛋白及其肿瘤免疫疗效研究

from 聊聊Sci

这项研究开发了一种名为 T-12 的新型免疫治疗融合蛋白,它通过将 IL-12 细胞因子与 TIGIT 靶向抗体片段结合,实现了对肿瘤区域的精准定位。与传统 IL-12 疗法因全身激活导致的严重毒性不同,T-12 能够特异性地聚集在肿瘤内部,从而显著降低了副作用并提高了药物耐受性。实验结果显示,该药物通过同时激活自然杀伤(NK)细胞和 CD8+ T 细胞,能有效遏制多种实体瘤的生长并清除癌症转移。此外,T-12 在应对不产生免疫反应的“冷”肿瘤以及对 PD-1 阻断剂不敏感的病例中展现出卓越的疗效。研究证明,这种通过抗体引导的精准递送策略,为提升癌症免疫治疗的安全性和有效性提供了极具潜力的方向。References:Tang M, Huang Y, Bi J, et al.
