Sepsis
脓毒症
Sepsis is a life-threatening medical condition caused by the body's extreme response to infection.
脓毒症是由身体对感染产生的极端反应引起的一种危及生命的疾病。
When a localized infection escapes and spreads through the body, the immune system produces signaling molecules in the bloodstream that can trigger widespread inflammation.
当局部感染逃逸，并在体内传播时，免疫系统在血液中产生触发广泛炎症的信号分子。
If left untreated, sepsis can result in organ failure and death.
如果不治疗，脓毒症会导致器官衰竭和死亡。
A molecule called C5a plays a critical role in sepsis.
一种称为 C5a 的分子在脓毒症中起着关键作用。
The body naturally produces C5a to fight infection, but in the early stages of sepsis, the immune system is activated systemically in the body. This results in higher levels of C5a.
身体自然产生 C5a 来抵抗炎症，但是，在脓毒症早期阶段，身体的免疫系统被激活，导致 C5a 水平升高。
C5a binds to surface receptors on immune cells and stimulates release of pro-inflammatory cytokines such as IL-8 and TNF-α.
C5a 与免疫细胞上的表面受体结合，刺激 IL-8 和 TNF-α 等促炎细胞因子释放。
