Initial elimination of invading Staphylococcus aureus from the body is mediated by professional phagocytes. The neutrophil is the major phagocyte of the innate immunity and plays a key role in the host defense against staphylococcal infections. Opsonization of the bacteria with immunoglobulins and complement factors enables efficient recognition by the neutrophil that subsequently leads to intracellular compartmentalization and killing. Here, we provide a review of the key processes evolved in neutrophil-mediated phagocytosis of S. aureus and briefly describe killing. As S. aureus is not helpless against the professional phagocytes, we will also highlight its immune evasion arsenal related to phagocytosis.
机体对入侵金黄色葡萄球菌的初始清除由专职吞噬细胞介导。中性粒细胞是固有免疫的主要吞噬细胞,在宿主抵御葡萄球菌感染中起关键作用。细菌通过免疫球蛋白和补体因子进行调理作用,从而能够被中性粒细胞有效识别,随后导致细菌被包裹在细胞内并被杀死。在此,我们综述了中性粒细胞介导的吞噬金黄色葡萄球菌过程中涉及的关键步骤,并简要描述细菌的杀伤机制。由于金黄色葡萄球菌并非对专职吞噬细胞毫无抵抗能力,我们还将重点介绍其与吞噬作用相关的免疫逃逸机制。
