为探究草酸性肾病的发病机制,许艳芳教授团队构建了草酸盐诱导的急性肾损伤小鼠模型,发现敲除坏死样凋亡的核心信号分子ZBP1/RIPK3/MLKL能显著逆转小鼠肾脏损伤。在机制上,作者发现草酸钙刺激肾小管上皮细胞诱导氧化应激致线粒体损伤释放Z-m...
总之,这些结果表明,虽然 RIPK3 的激酶活性决定了坏死性凋亡的激活,但其支架功能在 SARS-CoV-2 感染期间介导了炎症信号传导。 为了研究 ZBP1-RIPK3 触发的炎症反应的调节机制,作者用 FLAG 标记的全长 ZBP1 (ZBP1) 或删除 Zα2 域或 RHIM 域的 ZBP1 截断突变体 (ZBP1-∆Zα2) 重建 ZBP1 KO Calu-...
Z-DNA binding protein 1 (ZBP1) has important functions in anti-viral immunity and in the regulation of inflammatory responses. ZBP1 induces necroptosis by directly engaging and activating RIPK3, however, the mechanisms by which ZBP1 induces inflammation and in particular the role of RIPK1 and ...
Genetic ablation of mice for up to 3 mo beyond parturition. Together, these studies implicate ZBP1 as the dominant activator of IFN-driven RIPK3 activation and perinatal lethality in the absence of RIPK1. Copyright 2019 by The American Association of Immunologists, Inc....
This process activates Z-DNA binding protein 1 (ZBP1), which then interacts with receptor-interacting protein kinase 3 (RIPK3), ultimately leading to RIPK3-dependent necroptotic and ferroptotic signaling cascades. Specific deletion of eitherorin endothelial cells simultaneously inhibits both ...
ZBP1, an interferon-induced cytosolic nucleic acid sensor, facilitates antiviral responses via RIPK3. Although ZBP1-mediated cell death is widely described, whether and how it promotes inflammatory signaling is unclear. Here, we report a ZBP1-induced inflammatory signaling pathway that depends on ...
Further evidence showed that ASFV infection upregulates the expression of ZBP1 and RIPK3 to consist of the ZBP1-RIPK3-MLKL necrosome and further activates macrophage necroptosis. Subsequently, multiple Z-DNA sequences were predicted to be present in the ASFV genome. The...
The formation of Z-DNA and its co-localization with Z-DNA binding protein (ZBP1) was observed due to the nuclear envelope damage by IF. Western blot, qPCR, IHC and IF confirmed Z-DNA-induced inflammation in AVICs through the ZBP1-RIPK3-NF-魏B signaling pathway. ZBP1 and RIPK3 ...

We found that neuronal ZIKV infection activated the nucleotide sensor ZBP1 and the kinases RIPK1 and RIPK3, core components of virus-induced necroptotic cell death signaling. However, activation of this pathway in ZIKV-infected neurons did not induce cell death. Rather, RIPK signaling restricted...
