Fig. 6: Infection of bronchial epithelial cells with H1N1 resulted in prolonged upregulation of SARS-CoV-2 entry-related genes independent of viral titres.

a Gene expression analysis by qPCR of infected bronchial epithelial cells. Data shown as median ± confidence interval of paediatric (n = 5–6) and adult (n = 4) donors pooled together. Asterisks denote statistically significant change from uninfected control. Statistics: Mann–Whitney test. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. b Spearman correlation between viral titres and gene expression of indicated genes in cells infected with SARS-CoV-2 or H1N1. Correlation coefficients and p values are shown for each treatment individually (purple, SARS-CoV-2; teal, H1N1).
