For example, in the liver of patients with COVID-19, no significant differences were observed in macrophage (CD14 and CD68) counts compared with those in controls (Supplementary Figures 1A,B), and counts of CD11b+ macrophages, CD11c+ DCs, and CD3+ CD56+ NKT cells were also higher than those in the control, the exception being patient 1 (Supplementary Figures 1A,B). This evidence concerns the gene NCAM1 and COVID-19.
