α-Hemolysin (Staphylococcus aureus) BiologicalActivity
| Description | α-Hemolysin (Staphylococcus aureus) is one of the most characteristic virulence factors secreted by Staphylococcus aureus, a polypeptide capable of destroying the host cell plasma membrane. After α-Hemolysin binds to the cell surface, its monomers assemble into a homoheptamer to form a front pore, which then transforms into a mature transmembrane pore water channel, allowing K+ and Ca2+ ion transport, leading to necrotic death of target cells[1]. |

| In Vitro | α-Hemolysin (Staphylococcus aureus) 在 THP-1 细胞中可诱导 IL-1β 分泌和 caspase-1 激活，且是通过 NLRP3-炎性体依赖性 caspase-1 的激活诱导 IL-1β 分泌[1]。 α-Hemolysin (Staphylococcus aureus)(1 µg/mL, 4h) 可以诱导 THP 衍生细胞死亡，需要宿主 NLRP3 信号传导，但不依赖于 caspase-1 激活和 IL-1β 分泌[1]。 |
