缩小蛋白质靶向的差距
靶向蛋白质降解已成为一种极具前景的治疗方法,可用于调节传统小分子药物难以靶向的蛋白质。最近,这种方法已扩展到改变细胞外蛋白质的水平和活性--包括分泌蛋白和膜蛋白。现在,Zhang 等人利用癌细胞中细胞表面转铁蛋白受体 1(TfR1)的上调及其快速内吞速度,开发出了转铁蛋白受体靶向嵌合体(TransTACs)。研究小组研究了TransTACs消除表面嵌合抗原受体(CAR)的能力。尽管进行了内化,但 CAR 并没有被降解;相反,它被运送到了循环内体。为了解决这个问题,研究小组加入了TfR1抗体粘合剂和Cathepsin B裂解连接体,以促进CAR进入溶酶体降解途径。CAR TransTACs 能有效抑制 Jurkat 和人类原代 CAR T 细胞的活化以及 IFNγ 的分泌。此外,靶标范围还扩大到表皮生长因子受体(EGFR)(用于靶向耐药肺癌)以及 PD-L1 和 CD20,这证明了 TransTACs 能够有效内化和降解结构和功能不同的膜蛋白。

期刊介绍: Nature Chemical Biology stands as an esteemed international monthly journal, offering a prominent platform for the chemical biology community to showcase top-tier original research and commentary. Operating at the crossroads of chemistry, biology, and related disciplines, chemical biology utilizes scientific ideas and approaches to comprehend and manipulate biological systems with molecular precision. The journal embraces contributions from the growing community of chemical biologists, encompassing insights from chemists applying principles and tools to biological inquiries and biologists striving to comprehend and control molecular-level biological processes. We prioritize studies unveiling significant conceptual or practical advancements in areas where chemistry and biology intersect, emphasizing basic research, especially those reporting novel chemical or biological tools and offering profound molecular-level insights into underlying biological mechanisms. Nature Chemical Biology also welcomes manuscripts describing applied molecular studies at the chemistry-biology interface due to the broad utility of chemical biology approaches in manipulating or engineering biological systems. Irrespective of scientific focus, we actively seek submissions that creatively blend chemistry and biology, particularly those providing substantial conceptual or methodological breakthroughs with the potential to open innovative research avenues. The journal maintains a robust and impartial review process, emphasizing thorough chemical and biological characterization.
