Fig 2: Comparison of monocytes and NK cell percentage amongst study groups. a. The stained PBMCs were gated on the monocyte population and CD3+CD19+ cells were excluded. Cell populations are displayed for CD16 and CD14 expression (upper FACS panel). One exemplary dot plot is shown per study group. The bar diagrams (lower panel) show the non-classical (CD16+CD14-), intermediate (CD16+CD14+) and classical (CD16-CD14+) monocytes. *P-value =0.05, **P-value =0.01 and ***P-value =0.001. b. UMAP plot for different subsets of monocytes (non-classical, intermediate and classical monocytes; left UMAP plot) from all the samples. Group comparisons among HC, mild and moderate (right UMAP plot). Colour-coded information is provided for either different subsets of monocyte populations or patient groups. c. The stained PBMCs were gated on lymphocyte population and further excluded the CD3+CD19+ cells and examined for the CD56 and CD8 expression in HC, mild, moderate and convalescent (upper FACS panel). One exemplary dot plot is shown per study group. The bar diagram shows the CD56+CD8+CD3-CD19- NK cells. *P-value =0.05.
