From: A model including CD15, ACE2 and age efficiently predicts COVID-19 severity

Expression of CD15, CD45, ACE2 and TMPRSS2 in blood of patients with COVID-19. Data is represented as normalized values using their respective FMOs. CD15 expression is significantly reduced in severe patients (9.216 ± 6.130 vs. 5.233 ± 2.168), as well as ACE2 (1.289 ± 0.350 vs. 0.854 ± 0.138). CD45 is slightly increased in severe patients (1.289 ± 0.399 vs. 1.442 ± 0.367). There is no difference in the expression of TMPRSS2 (1.280 ± 0.186 vs. 1.309 ± 0.131). Each dot represents a sample. Welch’s t-test, ns = not significant.
