piRNA expression in cells of healthy donors and severe COVID−19 patients. Panel A. Log transformed raw expression data is presented in the heatmap, where 5 (red) indicates maximum expression values, and < 1 (green) minimum. Erythrocytes (Er), Monocytes (Mon), Lymphocytes (Lym), Eosinophils (Eos), Basophils (Bas) Neutrophils (Neu). Panel B. Control donors. Percentages of different piRNA in each cell type are shown on the left. SEM images of sorted cells are displayed on the right. Scale bar is equal to 5 μm. Panel C. Severe COVID−19 patients. Percentages of different piRNA in each cell type are shown on the left. SEM images of sorted cells are displayed on the right. Scale bar is equal to 5 μm
