SARS-CoV-2 and innate immune response in proviral factor-knockout cells
(A–C) Quantification of IFNβ (A), CXCL10 (B), IL-6, and TNF-α (C) mRNA in TRIM28, TRIM33, EHMT1, or EHMT2 knockout cells at 24 h post-infection. Poly(I:C) (high molecular weight) was transfected as a positive control in control cells, and cells were harvested 24 h post-infection. For TNF-α, human reference cDNA (30 ng equiv. total RNA) was used as a positive control for qPCR detection. Data are presented as the mean ± SD of three independent experiments. N.D., not detected.
