Gliotoxin 是一种次生代谢产物，是 A. fumigatus 分泌的最丰富的霉菌毒素，抑制巨噬细胞的吞噬作用和其他免疫细胞的免疫功能。Gliotoxin 通过阻止 IκB 降解来抑制诱导型 NF-κB 活性，从而诱导宿主细胞凋亡 (apoptosis)。 Gliotoxin 可以激活 PKA 并增加细胞内 cAMP 浓度; 调节肌动蛋白细胞骨架重排以促进 A. fumigatus 内化到肺上皮细胞。
| 生物活性 |
Gliotoxin is a secondary metabolite, the most abundant mycotoxin secreted by A. fumigatus, inhibits the phagocytosis of macrophages and the immune functions of other immune cells . Gliotoxin inhibits inducible NF-κB activity by preventing IκB degradation, which consequently induces host-cell apoptosis. Gliotoxin activates PKA and increases intracellular cAMP concentration; modulates actin cytoskeleton rearrangement to facilitate A. fumigatus internalization into lung epithelial cells. |
