General description
研究领域:免疫和CKS
Adenylate Cyclase Toxin(ACT或CyaA)是由革兰氏阴性菌产生的毒素重复序列(称为Repeat in Toxin,RTX)的一员。ACT由cyaA基因编码,并以可溶性蛋白的形式在细胞外分泌。它具有腺苷酸环化酶活性和溶血活性。ACT的合成、成熟和分泌受CyaCABD操纵子调控。此外,其特异性细胞受体CD11b/CD18整合素(αMβ2、Mac-1或CR3)在髓系吞噬细胞上表达。

Application
来自百日咳鲍特菌的腺苷酸环化酶毒素被用作Gα(i/o)抑制剂来研究鞘氨醇1-磷酸受体2/Gα(12/13)/MAPK信号通路在胆汁淤积型肝损伤时NLRP3炎症小体的预备和激活中的作用。
Biochem/physiol Actions
腺苷酸环化酶毒素(CyaA)通过损害氧化反应和趋化性,抑制中性粒细胞和巨噬细胞的吞噬活性,最终导致细胞凋亡或坏死。此外,ACT可上调树突状细胞上MHC II类和共刺激分子的表达,从而减少促炎细胞因子的产生。

NLRP3 inflammasome-driven inflammation represents a key trigger for hepatic fibrogenesis during cholestatic liver injury. However, whether sphingosine 1-phosphate (S1P) plays a role in NLRP3 inflammasome priming and activation remains unknown. Here, we found that the expression of NLRP3 in macrophages
