Molecular characterization and immune protection of an AN1-like zinc finger protein of Eimeria tenella.
Article in Parasitology research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Coccidiosis is caused by multiple species of the apicomplexan protozoa Eimeria. Among them, Eimeria tenella is frequently considered to be the most pathogenic. Zinc finger proteins (ZnFPs) are a type of protein containing zinc finger domains. In the present study, a putative Eimeria tenella AN1-like ZnFP (E. tenella AN1-like zinc finger domain-containing protein, putative partial mRNA, EtAN1-ZnFP) was cloned and characterized, and its immune protective effects were evaluated. The 798-bp ORF sequence of EtAN1-ZnFP that encoded a protein of approximately 27.0 kDa was obtained. The recombinant EtAN1-ZnFP protein (rEtAN1-ZnFP) was expressed in Escherichia coli. Western blot analysis showed that the recombinant protein was recognized by the anti-GST monoclonal antibody and anti-sporozoite protein rabbit serum. qPCR analysis revealed that EtAN1-ZnFP was highly expressed in unsporulated oocysts and sporozoites. Immunostaining with an anti-rEtAN1-ZnFP antibody indicated that EtAN1-ZnFP was uniformly distributed in the cytoplasm of sporozoites, except for the refractive body; furthermore, this protein was evenly distributed in the cytoplasm of immature schizonts but seldom distributed in mature schizonts. The results of the in vitro invasion inhibition assay indicated that the antibodies against rEtAN1-ZnFP efficiently reduced the ability of E. tenella sporozoites to invade host cells. Animal challenge experiments demonstrated that the chickens immunized with rEtAN1-ZnFP protein significantly decreased mean lesion scores and fecal oocyst output compared with challenged control group. The results suggest that EtAN1-ZnFP can induce partial immune protection against infection with E. tenella and could be an effective candidate for the development of new vaccines.
