A mechanism of immunoreceptor tyrosine-based activation motif (ITAM)-like sequences in the capsid protein VP2 in viral growth and pathogenesis of Coxsackievirus B3.

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
Coxsackievirus B3 (CVB3) is an RNA virus that mainly causes myocarditis. We have reported previously that immunoreceptor tyrosine-based activation motif (ITAM)-like sequences are contained in the capsid protein VP2 of CVB3. The substitution of two tyrosines for phenylalanines in the ITAM-like region causes attenuation of CVB3, possibly via defective viral assembly. In this study, we found that Syk, a downstream molecule of ITAM, interacts with the wild-type (WT) CVB3 VP0 protein, but not with the mutant CVB3 VP0 (called YYFF), and that an inhibitor of Syk reduced the growth of CVB3. The WT CVB3 activated nuclear factor kappa B (NF-κB), a protein activated by ITAM, and eventually induced the production of interleukin-6 (IL-6)-one of the proinflammatory cytokines induced by NF-κB-in macrophages. However, the YYFF form did not. In addition, viral VP2 protein may be dependent on the phosphorylation of an ITAM-like region that affected the activation of NF-κB. Taken together, these results suggest that the ITAM-like sequences in CVB3 VP2 can not only affect viral structure but also act as signals in pathogenesis.
