这些证据表明,在含有高浓度ATP的线粒体膜附近,MDA5对RNA的有效识别有助于远程调控K63-polyUb10-MDA5CARDs复合体的稳定性,并帮助激活MAVS。 综上所述,该研究通过生物大分子氢氘交换质谱和冷冻电镜技术发现长链,非锚定K63-polyUb类似...
综上所述,该研究通过生物大分子氢氘交换质谱和冷冻电镜技术发现长链,非锚定K63-polyUb类似于一个“分子桥梁”,促进了MDA5CARDs四聚体的组装,使之形成一个激动状态的构象来招募下游MAVSCARD,以进一步促进MAVSCARD的寡聚和激活(图3)。激活状态下的MDA5可以结合并水解ATP,远程提升CARDs-K63-polyUb10的稳定性以持续...
与抗体阴性DM相比,MDA5+DM患者呈现出不同的线粒体病理特征。MDA5+DM患者肌肉中MAVS-IFN1信号通路活性轻度加强。这种差异表明两组皮肌炎患者可能存在不同的肌肉损伤机制。 原文 Mitochondrial morphology and MAVS-IFN1 signaling pathway in muscles of anti-MDA5 dermatomyositis Abstract Objective: This study aimed ...
show that ADAR1 suppresses activation of the intracellular RNA sensor pathway mediated by Mda5 and MAVS. Adar -null embryos are 'rescued' by loss of expression of either Mda5 or MAVS. RNA sequencing analyses reveal that only 20% of the genes dysregulated in Adar / embryos are MAVS-dependent...

Objective: This study aimed to investigate mitochondrial changes and the mitochondrial antiviral-signaling protein (MAVS)-type I interferon (IFN1) signaling pathway in the muscles of anti-melanoma differentiation gene 5(MDA5) dermatomyositis (DM) patients. Methods: Eleven anti-MDA5 DM and ten ...
MAVS and the delayed and type I interferon-dependent expression of antiviral genes by the latter pool of MAVS (Dixitet al., 2010). Moreover, RIG-I can also trigger an MAVS-independent pathway that involves the signaling adaptor ASC independently ofNLRP3and leads to the production of IL-1β...
6 SCoV2 PLpro does not affect RIG-I ubiquitination and preferentially antagonizes the MDA5 pathway. a, ISGylation of FLAG–MDA5 in HEK293T cells that were co-transfected for 20 h with vector or V5-tagged SCoV2 PLpro WT or mutants, along with V5-ISG15, HA-Ube1L, and FLAG-UbcH8, ...
