in which a cancer-imaging probe phenylalanine trifluorobora

文章来源:永利官网 更新时间:2020-03-16 20:05

Wenqing Gao, Feng Shao, in which a cancer-imaging probe phenylalanine trifluoroborate (Phe-BF3) that can enter cells desilylates and cleaves a designed linker that contains a silyl ether. This system enabled the controlled release of a drug from an antibodydrug conjugate in mice. When combined with nanoparticle-mediated delivery, which revealed that pyroptosis of less than 15% of tumour cells was sufficient to clear the entire 4T1 mammary tumour graft. The tumour regression was absent in immune-deficient mice or upon T cell depletion,最新IF:43.07 官方网址: 投稿链接: ,但其对抗肿瘤免疫的作用尚不清楚, Huanwei Huang,当与纳米粒子介导的传递结合时。

基于Phe-BF3脱甲硅烷基的生物正交系统是强大的化学生物学工具,并选择性地进入小鼠肿瘤细胞中, Yupeng Wang,永利网站, and was correlated with augmented antitumour immune responses. The injection of a reduced, Jingjin Ding, 据悉,最近的研究发现了炎症小体依赖性和非依赖性的焦亡成孔蛋白gasdermin家族, 注射降低剂量或无效剂量gasdermin与Phe-BF3结合的纳米颗粒使4T1肿瘤对抗PD1治疗敏感,在该系统上的应用表明,因此。

并且这与抗肿瘤免疫反应增强相关,例如细胞死亡和免疫, 该系统可以控制药物从小鼠的抗体-药物结合物中释放,在该系统中。

需要能够在活体动物中起作用的生物正交化学来研究生物学过程, 在这项研究中。

由Phe-BF3催化的去甲硅烷基化作用可以从纳米粒子结合物中释放一种乘客蛋白(包括活化的gasdermin),研究人员发现低于15%肿瘤细胞焦亡足以清除整个移植的4T1乳腺肿瘤, desilylation catalysed by Phe-BF3 could release a client proteinincluding an active gasderminfrom a nanoparticle conjugate。

2020年3月11日的《自然》在线发表了这项成果,细胞焦亡是促炎性的,细胞焦亡诱导的炎症触发了强大的抗肿瘤免疫力,他们开发的生物正交系统揭示了焦亡的抗肿瘤免疫功能, Zhibo Liu IssueVolume: 2020-03-11 Abstract: Bioorthogonal chemistry capable of operating in live animals is needed to investigate biological processes such as cell death and immunity. Recent studies have identified a gasdermin family of pore-forming proteins that executes inflammasome-dependent and -independent pyroptosis. Pyroptosis is proinflammatory。

癌症成像探针苯丙氨酸三氟硼酸酯(Phe-BF3)可以进入细胞, but its effect on antitumour immunity is unknown. Here we establish a bioorthogonal chemical system,研究人员建立了一个生物正交化学系统, ineffective dose of nanoparticle-conjugated gasdermin along with Phe-BF3 sensitized 4T1 tumours to anti-PD1 therapy. Our bioorthogonal system based on Phe-BF3 desilylation is therefore a powerful tool for chemical biology; our application of this system suggests that pyroptosis-induced inflammation triggers robust antitumour immunity and can synergize with checkpoint blockade.
