疟原虫动合子在遇到蚊子血淋巴中的补体系统之前穿过中肠上皮细胞。我们确定了血红素过氧化物酶(HPX2)和NADPH氧化酶5(NOX5)作为中肠上皮硝化和抗疟原虫免疫的关键介质,增强冈比亚按蚊的一氧化氮毒性。我们表明,两个免疫机制,目标动合子上皮硝化和含硫酯蛋白1(TEP1)介导的裂解工作顺序,并提出上皮硝化作为一个调理素样系统,促进激活蚊子补体级联。
Plasmodium ookinetes traverse midgut epithelial cells before they encounter the complement system in the mosquito hemolymph. We identified a heme peroxidase (HPX2) and NADPH oxidase 5 (NOX5) as critical mediators of midgut epithelial nitration and antiplasmodial immunity that enhance nitric oxide toxicity in Anopheles gambiae. We show that the two immune mechanisms that target ookinetes—epithelial nitration and thioester-containing protein 1 (TEP1)-mediated lysis—work sequentially and propose that epithelial nitration works as an opsonization-like system that promotes activation of the mosquito complement cascade.
