疟疾每年威胁数百万人,是人类健康和经济发展的负担。不幸的是,在疾病控制方面,没有有效的疫苗,治疗效果受到耐药性的限制。由于缺乏可靠的遗传分析方法,恶性疟原虫的遗传操作受到阻碍。基于电穿孔的转染方法可以研究恶性疟原虫的基因功能,但效率较低。与传统的电穿孔方法相比,研究人员开发了一种脂质纳米颗粒,可以在报告基因分析中提高核靶向pDNA的效率。该方法首次促进了恶性疟原虫环状和线性DNA的转染,从而作为一种替代电穿孔的方法,提高了转染效率。对这些生物进行功能基因组研究的可靠方法的可用性可能是发现开发药物和疫苗的新靶点的催化剂。
Malaria threatens millions of people annually and is a burden to human health and economic development. Unfortunately in terms of disease control, no effective vaccines are available and the efficacy of treatment is limited by drug resistance. Genetic manipulation in Plasmodium falciparum is hampered due to the absence of robust methods for genetic analyses. Electroporation-based transfection methods have allowed the study of gene function in P. falciparum, with low efficiency. A lipid nanoparticle was developed that allowed nuclear targeting of pDNA with increased efficiency in reporter assay, compared to traditional electroporation method. This method has for the first time, facilitated transfection using both circular and linear DNA in P. falciparum thereby serving as an alternative to electroporation with an increase in transfection efficiency. Availability of a robust method for functional genomic studies in these organisms may be a catalyst for discovery of novel targets for developing drugs and vaccines.
