For many years, staphylococci have been detected mainly in infections of the skin and soft tissues, organs, bone inflammations, and generalized infections. Thromboembolic diseases have also become a serious plague of our times, which, as it turns out, are closely related to the toxic effects of staphylococci. because of the presence of many different kinds of virulence factors, is capable of manipulating the host's innate and adaptive immune responses. These include toxins and cofactors that activate host zymogens and exoenzymes, as well as superantigens, which are highly inflammatory and cause leukocyte death. Coagulases and staphylokinases can control the host's coagulation system. Nucleases and proteases inactivate various immune defense and surveillance proteins, including complement components, peptides and antibacterial proteins, and surface receptors that are important for leukocyte chemotaxis. On the other hand, secreted toxins and exoenzymes are proteins that disrupt the endothelial and epithelial barrier as a result of cell lysis and disintegration of linking proteins, which ultimately increases the risk of thromboembolism. In this review, we discuss various virulence factors and substances that may inhibit their activity.
多年来,葡萄球菌主要在皮肤和软组织感染、器官感染、骨炎症以及全身性感染中被检测到。血栓栓塞性疾病也已成为我们这个时代的严重祸患,事实证明,它们与葡萄球菌的毒性作用密切相关。由于存在多种不同的毒力因子,葡萄球菌能够操纵宿主的固有免疫和适应性免疫反应。这些毒力因子包括激活宿主酶原和外酶的毒素及辅助因子,以及具有高度炎症性并导致白细胞死亡的超抗原。凝固酶和葡萄球菌激酶可控制宿主的凝血系统。核酸酶和蛋白酶会使各种免疫防御和监测蛋白失活,包括补体成分、肽和抗菌蛋白,以及对白细胞趋化性很重要的表面受体。另一方面,分泌的毒素和外酶是由于细胞裂解和连接蛋白解体而破坏内皮和上皮屏障的蛋白质,这最终增加了血栓栓塞的风险。在本综述中,我们讨论了各种毒力因子以及可能抑制其活性的物质。
