Observations were similar when the input MOI was reduced to 0.001 (Fig. S1 ), except that titers of SARS-CoV-1 in Calu-3 cells were already very low in the absence of any IFN-a, resulting in a nonsignificant effect of additional IFN. Our data thus indicate that (i) if anything, ruxolitinib is an enhancer rather than an inhibitor of SARS-CoV-2 multiplication, and (ii) the boosting effect is most likely due to inhibition of the antiviral JAK/ STAT signaling pathway, because it is not present in the IFN induction-deficient Vero E6 cells. For the statistical testing of the dose-response effect of IFN (type I and III) against SARS-coronaviruses, the typical regression procedures were not applicable because of several values below the detection limit and some ties in the data. ./cache/cord-343515-fad1yyqx.txt ./txt/cord-343515-fad1yyqx.txt
