The antiphospholipid syndrome is characterized clinically by fetal loss and thrombosis and serologically by the presence of autoantibodies to lipid-binding proteins. In a model of this procoagulant condition in which these antibodies are injected into pregnant mice, fetal loss was prevented by blocking of complement activation. Specifically, interaction of complement component 5a (C5a) with its receptor is necessary for thrombosis of placental vasculature. Inhibition of complement activation may have a therapeutic role in this disease.
抗磷脂综合征的临床特征为胎儿丢失和血栓形成,血清学特征为存在针对脂质结合蛋白的自身抗体。在将这些抗体注入怀孕小鼠的这种促凝状态模型中,通过阻断补体激活可预防胎儿丢失。具体而言,补体成分5a(C5a)与其受体的相互作用是胎盘血管系统血栓形成所必需的。补体激活的抑制可能在这种疾病中具有治疗作用。
