858-心肌修复与纤维化靶向树突状细胞免疫疗法
from 聊聊Sci
这份由多位学者于2026年发表的研究报告介绍了一种针对心脏修复的创新免疫疗法。研究人员开发了一种名为iCDCs的工程化免疫抑制树突状细胞,通过结合FAP靶向技术与多种免疫调节因子,实现对受损心肌的精准治疗。实验结果表明,该疗法能显著减少小鼠和非人灵长类动物模型中的心脏纤维化,并有效提升心肌灌注与收缩功能。iCDCs的核心机制在于重塑局部免疫微环境,特别是通过诱导调节性T细胞(Treg)的克隆扩增来抑制炎症。此外,该方案在不产生系统性毒性的前提下增强了血管生成,为治疗心力衰竭和病理性重构提供了极具前景的临床平台。References: Li X, Li J, Li G, et al.
