Figure Lengend Snippet: IFN-mediated restriction of SARS-CoV-2 relies on a limited subset of ISGs (A) Schematic representation of the gain-of-function screen to identify ISGs that inhibit SARS-CoV-2 replication. (B) Ranked log2FC of the percentage of infected cells (SARS-CoV-2 N + cells, blue shading) and normalized cell number (pink shading) after individual overexpression of 399 human ISGs and controls. Values are relative to the negative control CAT . Dashed lines illustrate cut offs for antiviral ISG hit calling strategy; the dotted blue line indicates log2FC infection = 4 × standard deviations (SDs) log2FC of CAT log2FC, and the dotted pink line indicates cell number = 70% of CAT . Controls are shown ( CAT , negative; LY6E , positive). (C) Correlation plots between screens. r, Pearson correlation coefficient. (D) 293T-ACE2 cells transduced with lentiviruses carrying each of the identified ISGs were infected with SARS-CoV-2 (MOI = 0.25) for 40 h prior to immunostaining for viral SARS-CoV-2 nucleoprotein (N). Data represent mean log2FC values (percentage of N + cells relative to parental control wells) from three independent experiments (n = 3). (E) Representative images are shown. Scale bars, 10 μm. (F) Calu-3 cells transduced with lentiviruses encoding the indicated ISGs were infected with SARS-CoV-2 (MOI =1.5) for 48 h prior to immunostaining for viral N protein. Data show mean ± SEM normalized infection (percentage of infected cells relative to parental control wells) from one representative experiment in quadruplicate (n = 4). (G) Differentiated HTBE cells stably expressing the indicating ISGs or negative control GFP were infected with SARS-CoV-2 (MOI = 1) on the apical side. At 18 h post-infection, supernatants were collected and the amount of SARS-CoV-2 focus-forming units per milliliter (FFU/mL) analyzed using Vero E6 cells. Data show mean ± SD and are representative from two sets of HTBE cells per ISG (n = 2). Statistical significance was calculated using one-way ANOVA with Sidak’s multiple comparison post hoc test (D) or one-way ANOVA with Dunnett’s post hoc test (F and G).

Figure Lengend Snippet: Interferon sensitivities of Daudi/ATCC cells. Cells were grown in the presence of various concentrations of IFN-α over a 28-day period, and the number of live cells (as a percentage of untreated cells) was plotted. The profile of Daudi/ATCC, showing viable cell counts as a percentage of cells grown in the absence of interferon (100%), is taken as a standard for medium IFN-α sensitivity. Superimposed on it are two curves from Daudi/ICRF cells (grown in the presence of 1 and 10 U of IFN-α/ml; high sensitivity), one from Raji cells (grown with 104 U; low sensitivity), and one from P3HR1 cells (102 U; high/medium sensitivity; data taken from the literature [2]), all EBV-positive lines.
