Human and rhesus plasmacytoid dendritic cell and B-cell responses to Toll-like receptor stimulation.

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
Interferon-α (IFN-α) produced at high levels by human plasmacytoid dendritic cells (pDCs) can specifically regulate B-cell activation to Toll-like receptor (TLR) 7/8 stimulation. To explore the influence of IFN-α and pDCs on B-cell functions in vivo, studies in non-human primates that closely resemble humans in terms of TLR expression on different subsets of immune cells are valuable. Here, we performed a side-by side comparison of the response pattern between human and rhesus macaque B cells and pDCs in vitro to well-defined TLR ligands and tested whether IFN-α enhanced B-cell function comparably. We found that both human and rhesus B cells proliferated while pDCs from both species produced high levels of IFN-α in response to ligands targeting TLR7/8 and TLR9. Both human and rhesus B-cell proliferation to TLR7/8 ligand and CpG class C was significantly increased in the presence of IFN-α. Although both human and rhesus B cells produced IgM upon stimulation, only human B cells acquired high expression of CD27 associated with plasmablast formation. Instead, rhesus B-cell differentiation and IgM levels correlated to down-regulation of CD20. These data suggest that the response pattern of human and rhesus B cells and pDCs to TLR7/8 and TLR9 is similar, although some differences in the cell surface phenotype of the differentiating cells exist. A more thorough understanding of potential similarities and differences between human and rhesus cells and their response to potential vaccine components will provide important information for translating non-human primate studies into human trials.
