    Flow cytometry: Cells were stained using Live/Dead Blue (Invitrogen), incubated with human FcR blocking reagent (Miltenyi Biotec) and stained with antibodies against the following surface proteins: CD1c (AD5-8E7; Miltenyi Biotec), CD3 (SK7; BD), CD11c (B-Ly6; BD)
    CD3
    suggested: None
    CD11c
    suggested: None
    Detection was performed with a goat anti-human IgG HRP-conjugated secondary antibody (clone G18-145 from BD Biosciences) followed by incubation with TMB substrate (BioLegend; cat# 421101) and stopped with a 1M solution of H2SO4.

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).


    Results from LimitationRecognizer: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.

    Results from TrialIdentifier: No clinical trial numbers were referenced.


    Results from Barzooka: We did not find any issues relating to the usage of bar graphs.


    Results from JetFighter: Please consider improving the rainbow (“jet”) colormap(s) used on page 36. At least one figure is not accessible to readers with colorblindness and/or is not true to the data, i.e. not perceptually uniform.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
