Longitudinal UMAP analyses of NK cell clusters. UMAP analyses reveal a population of NK cells (circled) which expands from baseline (A, D, G) to 4–7 days (B, E, H) and 35 days (C, F, I) post-infection. This expansion was found when all donor samples were examined (A–C), and when examining the asymptomatic donors (D–F) and symptomatic donors (G–I) separately. Alignment with phenotypic markers reveals this population to be comprised of immature NK cells (see Supplemental Fig. 2).
