Poliovirus type 1 infection of murine PRNP-knockout neuronal cells.
Article in Journal of neurovirology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Transfection of the prion protein gene (Prnp) into prion-deficient mouse cells was shown to reduce the replication of coxsackievirus B3, an enterovirus. Because mice can be susceptible to poliovirus infection by parenteral routes, the authors tested the susceptibility to poliovirus-1 (PV-1) of a panel of murine neuronal cell lines differing in their ability to express Prnp. The investigated cell lines (prionless HpL3.4 cells, HpL3.4 cells transfected with a Prnp vector, HpL3.4 cells transfected with a void vector, wild-type Hw3.5 Prnp(+/+) cells) expressed the murine homologue (Tage4) of human poliovirus receptor (CD155/hPVR). PV-1 infection of Prnp(-/-) HpL3.4 cells resulted in the production of high viral titers, though viral antigens could be detected in only 0.5% to 2% of cells. Wild-type Prnp(+/+) cells and prionless cells transfected with the Prnp gene were not permissive to PV-1. Results of viral titration and immunofluorescence were confirmed by conventional polymerase chain reaction (PCR) and quantitative real-time PCR. Exposure to PV-1 had no influence on the gene expression profile of Prnp(+/+) cells. In contrast, PV-1 infection was associated with upregulation of several genes in permissive Prnp(-/-) cell cultures: type I interferon (IFN) genes, IFN-related developmental regulator 1 (IFNRD1), tumor necrosis factor superfamily member 13b (TNFSF13b), interleukin (IL) - 7, granulocyte/macrophage colony-stimulating factors (CSFs), hepatocyte growth factor (HGF), vascular endothelial growth factor-A, transforming growth factors beta1 and beta3 (TGFb1, TGFb3), as well as a variety of bone morphogenetic proteins endowed with neuroprotective activity. Distinction of permissive from nonpermissive neuronal cells on the basis of Prnp expression suggests that prion-deficient mice could represent an extraordinarily sensitive animal model for poliovirus infection.
