链球菌溶素O 用途与合成方法

分类

按对绵羊红细胞溶血能力可分为：①甲型(a)溶血性链球菌，又称草绿色链球菌，是人类呼吸道及肠道的正常寄居菌，致病力低。②乙型(β)溶血性链球菌，又称溶血性链球菌，致病力强，可引起人或动物多种疾病。③丙型链球菌，又称非溶血性链球菌，一般无致病性，常存在于乳品及粪便中。其中研究最多的为乙型(β)溶血性链球菌。

生物活性

Streptolysin O，A组链球菌毒素，是一个氧不稳定原型胆固醇结合细菌外毒素。Streptolysin O 导致细胞裂解和心脏毒性。Streptolysin O 用于细胞膜的可控渗透性。Streptolysin O 以两种形式存在，即还原活性状态和氧化可逆不活动状态。

体外研究

Streptolysin O is a labile toxin, and, with time, activity is irreversibly lost. The rate of activity loss is slowed by incubation with 0.1 M 2-mercaptoethanol or 0.01 M ethylenediaminetetraacetic acid (EDTA).  
 Streptolysin O, belongs to the group of thiol-activated toxins, is a secreted virulence factor of GAS that induces apoptosis in neutrophils and macrophages at later time points (~4 h). Streptolysin O induces eukaryotic cell lysis in a cholesterol-dependent manner, is highly upregulated in the GAS M1T1 clone during bloodstream dissemination. Streptolysin O is known to promote Group A Streptococcus (GAS) resistance to phagocytic clearance by neutrophils, a critical first element of host defense against invasive bacterial infection.
