致命的疟疾寄生虫恶性疟原虫(Plasmodium falciparum)的蚊媒传播是由成熟的有性形式(配子体)介导的。在脊椎动物宿主中循环,相对较少的红细胞内配子母细胞在血餐期间被拾取以在蚊子载体中继续性发育。因此,人与病媒的传播是寄生虫生命周期中预防疟疾的治疗性干预措施的一个感染瓶颈。尽管最近在识别与配子体发生相关的遗传因素方面取得了进展,但对性阶段发育至关重要的大量基因尚未被解开。在这篇综述中,我们通过讨论配子体的靶向特征来重新审视恶性疟原虫传播生物学,并提供了一个未来识别新型传播阻断候选者的前瞻性遗传方法的视角。
Mosquito transmission of the deadly malaria parasite Plasmodium falciparum is mediated by mature sexual forms (gametocytes). Circulating in the vertebrate host, relatively few intraerythrocytic gametocytes are picked up during a bloodmeal to continue sexual development in the mosquito vector. Human-to-vector transmission thus represents an infection bottleneck in the parasite’s life cycle for therapeutic interventions to prevent malaria. Even though recent progress has been made in the identification of genetic factors linked to gametocytogenesis, a plethora of genes essential for sexual-stage development are yet to be unraveled. In this review, we revisit P. falciparum transmission biology by discussing targetable features of gametocytes and provide a perspective on a forward-genetic approach for identification of novel transmission-blocking candidates in the future.
