Matrix protein-specific IgA antibody inhibits measles virus replication by intracellular neutralization.
Article in Journal of virology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Measles virus (MV) is still an imposing threat to public health. The matrix (M) protein has been shown not only to function as a structure block in the assembled MV virions, but also to regulate viral RNA synthesis, playing an important role in MV's replication and assembly. In the present study, we generated a panel of IgG monoclonal antibodies (MAbs) against M protein and successfully obtained one IgA MAb (5H7) from the IgG panel. Employing the polarized Vero cells grown in the two-chamber transwell model, we investigated whether M-specific 5H7 IgA MAb could suppress MV's replication and assembly. The data presented indicate that, while failing to show the activities of traditional neutralization and immune exclusion, M-specific IgA MAb was able to effectively inhibit viral replication by intracellular neutralization (78%), supporting the notion that the M protein is important for MV assembly and replication and implying that the M protein was an effective target antigen. The data also showed that MV had a long entry and assembly phase during viral replication, providing an extended window for IgA intervention. The colocalization of M proteins and M-specific 5H7 IgA MAbs demonstrated that the intracellular neutralization was due to the direct binding of the M-specific 5H7 IgA MAbs to the M proteins. In summary, the present study has added another example showing that IgA antibodies targeting internal viral antigens could proactively participate in mucosal immune protection by intracellular neutralization and has provided evidence that M protein might be included as a target antigen in future MV vaccine design.
