Orf Virus-Based Vectors Preferentially Target Professional Antigen-Presenting Cells, Activate the STING Pathway and Induce Strong Antigen-Specific T Cell Responses.
Article in Frontiers in immunology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Background: Orf virus (ORFV)-based vectors are attractive for vaccine development as they enable the induction of potent immune responses against specific transgenes. Nevertheless, the precise mechanisms of immune activation remain unknown. This study therefore aimed to characterize underlying mechanisms in human immune cells. Methods: Peripheral blood mononuclear cells were infected with attenuated ORFV strain D1701-VrV and analyzed for ORFV infection and activation markers. ORFV entry in susceptible cells was examined using established pharmacological inhibitors. Using the THP1-Dual™ reporter cell line, activation of nuclear factor-κB and interferon regulatory factor pathways were simultaneously evaluated. Infection with an ORFV recombinant encoding immunogenic peptides (PepTrio-ORFV) was used to assess the induction of antigen-specific CD8+ T cells. Results: ORFV was found to preferentially target professional antigen-presenting cells (APCs) Discussion: Our findings confirm that ORFV induces a strong antigen-specific immune response dependent on APC uptake and activation. These data support the notion that ORFV D1701-VrV is a promising vector for vaccine development and the design of innovative immunotherapeutic applications.
