Heterologous Expression of Human IFNγ and Anti-IL17 Antibody in Leishmania tarentolae Promastigote.
Background: Leishmania is an intracellular flagellate protozoan parasite that causes a wide range of clinical diseases in humans. The basis of immunological resistance against leishmaniasis depends on Thl reactions and is within the time period of cytokine function.
Methods: In this study, human anti-IL17 antibody and IFNγ-producing promastigote were produced to be used in leishmanization. A sequence of light and heavy chains' gene of anti-IL17 antibody and human IFNγ (hIFNγ) was obtained from the NCBI database and synthesized in the ECORV reaction site in the plasmid pGH, which it's called pGH-hIFNγ-antiIL17. The synthesized part using the restriction enzyme ECORV was extracted from the plasmid and after purification by electroporation was transferred to Iranian lizard Leishmania (I.L.L). Evaluation of structural presence in the I.L.L genome at the level of DNA and mRNA was assessed. The expressions of hIFNγ and anti-IL17 were evaluated and confirmed using ELISA and western blot analysis. The hIFNγ secreted from the culture medium was collected at high concentrations of 124.36 ± 6.47 pg/mL.
Results: Targeted gene replacement into the I.L.L genome was successfully performed for the first time using the pGH-hIFNγ-antiIL17 plasmid in an identical replacement process. Stabilized recombinant DNA contains a target gene that has no toxicity to the parasite.
Conclusions: The effective achievement of producing a recombinant gene was done for the first time by replacing the I.L.L-CPC gene with plasmid pGH-hIFNγ-antiIL17 by targeted gene replacement. This cab can regulate the production of hIFNγ and anti-IL17. This makes it a viable choice for eliminating leishmania.
期刊介绍:
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
