Brugia malayi: transient transfection by microinjection and particle bombardment.
نویسندگان
چکیده
To develop a method for the introduction of DNA into filarial parasites, several methods that have proven successful in other organisms were evaluated for their ability to transform Brugia malayi. Luciferase activity was detectable in embryos bombarded with gold particles coated with a construct consisting of a luciferase reporter gene under the control of the 5S rRNA intergenic spacer (SL promoter). Similar results were seen in adult parasites and infective larvae bombarded with this construct, or in adult female parasites microinjected with the plasmid. In similar experiments employing the SL promoter driving a green fluorescent protein (GFP) reporter, expression of the reporter was detectable in the intrauterine embryos of the microinjected adult parasites, and in the sub-cuticular tissues of biolistically transfected adult female parasites. A similar pattern of GFP expression to that seen in the SL promoter construct transfected parasites was noted in parasites transfected with constructs consisting of the upstream domain derived from an aspartyl aminoacyl tRNA synthetase gene of B. malayi. The ability to transfect B. malayi embryos may provide a foundation for studies of the regulation of gene expression and function in these organisms.

Electroporated intact BY-2 tobacco culture cells as a model of transient expression study.
Transfer of foreign genes into plant cells can be accomplished by several methods: agrobacterium-mediated, microinjection, biolistic particle bombardment and electroporation. The last one is frequently used for transfection of plant protoplasts for transient gene expression. Electroporation is a simple procedure and allows transfecting a large number of cells at one time. Square wave-modulated ...

Haploid microspore-derived embryos (MDEs) of wheat were obtained by in vitro androgenesis. These embryos were employed to evaluate the transient expression of GUS gene (uidA) following particle bombardment. Using the Bio-Rad PDS-1000/He system, the physical parameters including rupture disk pressure (900, 1100 and 1350 psi); microprojectile travel distance (6 and 9 cm); gold particles size (0....

Lymphatic filariasis has been targeted by the World Health Organization for elimination by the year 2020. Malayan filariasis, caused by Brugia malayi, is endemic in southern Thailand where domestic cats serve as a major reservoir host. However, in nature, domestic cats also carry B. pahangi infection. In addition to chemotherapy and vector control, control in reservoir hosts is necessary to ach...
