Plasmodium falciparum is the causative agent for the most lethal form of human malaria, killing millions annually. Genetic analyses of P. falciparum have been relatively limited due to the lack of robust techniques to manipulate this parasite. Development of transfection technologies and whole genome analyses have helped in understanding the complex biology of this parasite. Even with this wealth of information functional genomics approaches are still very limited in P. falciparum due to the cumbersome and inefficient methods of genetic manipulation. This review focuses on a recently developed, highly efficient method for transposon-based mutagenesis and transgene expression in P. falciparum that will allow functional genomics studies to be performed proficiently on this deadly malaria parasite. By using a piggyBac-based transposition system, multiple random integrations have been obtained into the genome of the parasite. This technique could hence be employed to set up several biological screens in this lethal protozoan parasite that may lead to identification of novel drug targets and vaccine candidates.
恶性疟原虫是人类疟疾最致命形式的病原体,每年导致数百万人死亡。由于缺乏操纵这种寄生虫的可靠技术,对恶性疟原虫的基因分析相对有限。转染技术和全基因组分析的发展有助于了解这种寄生虫的复杂生物学特性。即便有了这些丰富的信息,但由于遗传操作方法繁琐且效率低下,功能基因组学方法在恶性疟原虫中仍然非常有限。本综述重点介绍了一种最近开发的、高效的基于转座子的诱变和转基因表达方法,该方法可用于恶性疟原虫,从而使功能基因组学研究能够在这种致命的疟原虫上顺利进行。通过使用基于piggyBac的转座系统,已在寄生虫基因组中实现了多个随机整合。因此,该技术可用于在这种致命的原生动物寄生虫中建立多个生物学筛选,这可能有助于识别新的药物靶点和疫苗候选物。
