a, UMAP embedding of CD4+ T, CD8+ T, and NK cells colored by expression of canonical pro-inflammatory cytokines IFNG, TNF, CCL3, and CCL4. n = 22,016 cells are plotted from n = 14 biologically independent samples. Dotted lines correspond to the cell type boundaries identified in Fig. 3b. b, Dot plot depicting average and percent expression of canonical cytotoxic lymphocyte pro-inflammatory cytokines by CD8+ T cells from n = 8 COVID-19 samples and n = 6 healthy controls.
