Characterization of peripheral blood mononuclear cells (PBMCs) in patients with COVID-19 and healthy donors. A The PBMC samples of all patients and the healthy donors were merged, and cell populations defined by the manual gating strategy were projected onto a t-SNE map and assigned specific colors. B Patient data within each group were concatenated by group, and CyTOF staining data for the three groups from CD45 + cells were analyzed by t-SNE and plotted as density contour plots. B cells B lymphocytes, CD4 T cells CD4 T lymphocytes, CD8 T cells CD8 T lymphocytes, D donor, HD healthy donors, HP hospitalized patients, MAIT mucosal-associated invariant T cells, NK natural killer cells, NKT natural killer T cells, HP hospitalized patient, RP recovered patient, HD healthy donor,  t-SNE t-distributed Stochastic Neighbor Embedding
