Platelets, as well as regulating blood hemostasis, are an important component of the body's defense against invading microbial pathogens. We previously reported that platelets protect during malaria infection by binding Plasmodium-infected erythrocytes (IE) and killing the parasite within. More recent studies have now revealed the platelet plasmocidal factor, platelet factor 4 (PF4) and the red cell-expressed Duffy-antigen molecule as the central players in the parasite killing activity of platelets.
血小板除了调节血液止血外,还是机体抵御入侵微生物病原体防御系统的重要组成部分。我们之前报道过,血小板在疟疾感染期间通过结合疟原虫感染的红细胞(IE)并杀死其中的寄生虫来发挥保护作用。最近的研究现已揭示,血小板杀菌因子、血小板因子4(PF4)以及红细胞表达的达菲抗原分子是血小板杀灭寄生虫活性的核心参与者。
