  • 产品描述:
        GSDMD(Gasdermin D)属于Gasdermin家族,在细胞焦亡的执行过程中起到关键作用。近年来的研究发现,GSDMD蛋白的切割会导致细胞膜上形成孔洞,诱导细胞焦亡发生,释放IL-1β和IL-18等炎性因子,加剧炎症反应的发生。GSDMD蛋白在科研上的应用主要集中在以下几个方面:
        ① 细胞焦亡研究,GSDMD蛋白是细胞焦亡的关键基因,通过膜打孔并导致细胞裂解性死亡。在巨噬细胞中,GSDMD蛋白通过N端切割产生p30片段,进而引发细胞焦亡和炎症
        ② 病原微生物研究,GSDMD蛋白在病原微生物感染的研究中也发挥着重要作用。例如,GSDMD蛋白在病原相关分子模式(PAMPs)和损伤相关分子模式(DAMPs)的刺激下,通过GSDMD的N端切割产生p30片段进而引发细胞焦亡和炎症。
        ③ 细胞焦亡机制研究:GSDMD蛋白在细胞焦亡机制研究中也扮演着重要角色。例如,GSDMD-N端与质膜内侧的小叶脂质结合,多聚生成直径10-15nm的孔,释放成熟的IL1b并触发焦亡。
        ④ 免疫调节研究,GSDMD蛋白在免疫调节研究中也有所应用。例如,GSDMD-N端从焦亡细胞释放到细胞外环境中,迅速与革兰氏阴性细菌和革兰氏阳性细菌结合并杀死它们。

  • 功能:
    Precursor of a pore-forming protein that plays a key role in host defense against pathogen infection and danger signals. This form constitutes the precursor of the pore-forming protein: upon cleavage, the released N-terminal moiety (Gasdermin-D, N-terminal) binds to membranes and forms pores, triggering pyroptosis.; Promotes pyroptosis in response to microbial infection and danger signals. Produced by the cleavage of gasdermin-D by inflammatory caspases CASP1, CASP4 or CASP5 in response to canonical, as well as non-canonical (such as cytosolic LPS) inflammasome activators. After cleavage, moves to the plasma membrane where it strongly binds to inner leaflet lipids, including monophosphorylated phosphatidylinositols, such as phosphatidylinositol 4-phosphate, bisphosphorylated phosphatidylinositols, such as phosphatidylinositol (4,5)-bisphosphate, as well as phosphatidylinositol (3,4,5)-bisphosphate, and more weakly to phosphatidic acid and phosphatidylserine. Homooligomerizes within the membrane and forms pores of 10-15 nanometers (nm) of inner diameter, allowing the release of mature IL1B and triggering pyroptosis. Exhibits bactericidal activity. Gasdermin-D, N-terminal released from pyroptotic cells into the extracellular milieu rapidly binds to and kills both Gram-negative and Gram-positive bacteria, without harming neighboring mammalian cells, as it does not disrupt the plasma membrane from the outside due to lipid-binding specificity. Under cell culture conditions, also active against intracellular bacteria, such as Listeria monocytogenes. Also active in response to MAP3K7/TAK1 inactivation by Yersinia toxin YopJ, which triggers cleavage by CASP8 and subsequent activation. Strongly binds to bacterial and mitochondrial lipids, including cardiolipin. Does not bind to unphosphorylated phosphatidylinositol, phosphatidylethanolamine nor phosphatidylcholine.
