Fig. 3From: Sputum ACE2, TMPRSS2 and FURIN gene expression in severe neutrophilic asthmaScatter dot plots showing correlations between sputum FURIN gene expression levels and a neutrophils (%), b enrichment score (ES) of neutrophil activation gene signature and c ES of IL6-trans-signaling (IL6-TS) gene signature in sputum of asthmatics (n = 104). Correlation coefficients and p values were determined by Spearman’s testsBack to article page
