Heterologous Expression of Human IFNγ and Anti-IL17 Antibody in Leishmania tarentolae Promastigote.
Article in Acta parasitologica, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLeishmania 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.
methodsIn 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.
resultsTargeted 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.
conclusionsThe 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.
