金黄色葡萄球菌的皮肤感染不仅是发病甚至死亡的重要原因,而且被认为是许多炎症性皮肤病的起始和/或持续性因素,包括牛皮癣和特应性皮炎。其中一个机制是。金黄色葡萄球菌通过产生超抗原毒素、蛋白A以及溶细胞α-毒素来调节免疫系统。这篇综述旨在讨论这三种类型的蛋白质的生物学,重点是它们在角质形成细胞中刺激产生强大的促炎脂质和蛋白质来源的细胞因子的能力。表征这些蛋白与角质形成细胞之间的相互作用可以更好地了解细菌感染如何调节炎症性皮肤病,并为改进涉及抗菌药物的治疗提供基础。
Skin infections withStaphylococcus aureusare not only an important cause of morbidity and even mortality, but are thought to serve as initiation and/or persistance factors for numerous inflammatory skin diseases, including psoriasis and atopic dermatitis. One mechanism by whichS. aureuscan modulate the immune system is through the production of proteins such as superantigenic toxins, Protein A, as well through the cytolytic α-toxin. This review serves to discuss the biology of these three types of proteins, with emphasis on their ability to stimulate the production of powerful pro-inflammatory lipid- and protein-derived cytokines in keratinocytes. Characterization of interactions between these proteins and the keratinocyte can provide a better understanding of how bacterial infection modulates inflammatory skin diseases, as well as provide the basis for improved therapies involving antibacterial agents.
