B cells, Neutrophil, Platelet, CD8+ T cells, CD4+ T cells, Basophil, Erythrocyte (RBC), Dendritic cell (DC), Monocyte, T helper (Th) cell totaling 10 types of cells (Figures 7A, B).The changes in their number of cells per population were counted and plotted (Figure 7C, Supplementary Figure S7), which showed a similar trend of decreasing numbers in both COVID-related and sepsis-related ARDS patients, which was slightly different from the analysis of mice. Here, CD4 is linked to Sepsis.
