Expression of Host Cell Receptor Genes in COVID-19 and Non-COVID-19 Patients
(A–F) Gene expression analysis for host cell receptor genes (A) ACE2, (B) TMPRSS2, (C) BSG/CD147, (D) CTSB, (E) CTSL, and (F) ADAM17.
(I) COVID-19 versus non-COVID-19 patients (p values correspond to Wilcoxon rank-sum test); (II) COVID-19 and non-COVID-19 patients by sex (p values correspond to Wilcoxon rank-sum test); (III) COVID-19 and non-COVID-19 patients categorized by age groups (p values correspond to decreasing Jonckheere-Terpstra trend test). Statistical significance was set at p < 0.05. NS: not significant.
