Immune gene expression in swine macrophages expressing the Torque Teno Sus Virus1 (TTSuV1) ORF-1 and 2 proteins.
Article in Virus research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Torque Teno viruses (TTVs) are small DNA viruses which are ubiquitous in nature. Recent reports indicate that swine torque teno viruses (TTSuVs) can act as primary pathogens or play a role in exacerbating co-infections. However, very little is known about the TTSuV host-viral interaction or how they so successfully establish chronic infections in the host. To determine whether the major viral proteins can modulate host immunity, recombinant TTSuV1 ORF1 and 2 proteins were expressed in a swine macrophage cell line (3D4/31). The differential expression of a panel of innate, adaptive, regulatory and inflammatory immune genes was studied by quantitative PCR; using cDNA samples collected at 6, 12, 24 and 48h post-transfection. The ORF1 protein induced an early anti-viral response. However, at 6h post-transfection it also upregulated IL-10, PD-1 and SOCS-1, the suppressors of T cell mediated immunity. An ensuing diminishment of the early protective response was noted. The TTSuV1 ORF2 protein suppressed IFN-β and IL-13 responses but did not significantly influence anti-viral immunity otherwise. These findings indicate that the TTSuV1 ORF1 protein plays a significant but dual role in viral immunity.
