Temporal transcriptional modulation of immune-related genes offers powerful therapeutic potential for treating inflammatory diseases. Here, we introduce an enhanced zinc finger (ZF)-based transcriptional repressor delivered via lipid nanoparticles for controlling immune signaling pathways . By targeting Myd88, an essential adaptor molecule involved in immunity, our system demonstrates therapeutic efficacy against septicemia in C57BL/6J mice and improves repeated AAV administration by reducing antibody responses. This epigenetic engineering approach provides a platform for safe and efficient immunomodulation applicable across diseases caused by imbalanced inflammatory responses.
免疫相关基因的时间转录调控为治疗炎症性疾病提供了强大的治疗潜力。在此，我们引入了一种通过脂质纳米颗粒递送的增强型基于锌指（ZF）的转录抑制因子，用于控制免疫信号通路。通过靶向髓样分化因子88（Myd88），一种参与免疫的关键衔接分子，我们的系统在C57BL/6J小鼠中显示出对败血症的治疗效果，并通过降低抗体反应改善了反复腺相关病毒（AAV）给药。这种表观遗传工程方法为安全有效地免疫调节提供了一个平台，适用于由炎症反应失衡引起的各种疾病。
