Editorial Expression of Concern to: Scientific Reports https://doi.org/10.1038/s41598-017-12998-w, published online 12 October 2017

The Editors are issuing an Editorial Expression of Concern to alert readers that concerns were raised regarding similarities within the FACS plots in Figure 1E and Supplementary Figure 2A of this Article. The Authors provided explanations for the matters raised; however, the original data were no longer available. As such, it was not possible to determine whether the descriptions of these figures are accurate. Readers are therefore advised to interpret the data presented in Figure 1E and Supplementary Figure 2A with caution.

Ariella Glasner, Batya Isaacson, Michal Mandelboim and Ofer Mandelboim disagreed with this Expression of Concern; Sergey Viukov and Jacob H. Hanna did not explicitly state their agreement or disagreement; Tzahi Neuman, Nehemya Friedman and Veronika Sexl did not respond to correspondence from the Editor.
