Fig. 3: Aging alters immune cell populations during COVID-19.

(a) Uniform Manifold Approximation and Projection (UMAP) plot highlighting blood cell types analyzed by CyTOF. (b) Bar plot depicting blood cell types that are upregulated (red) or downregulated (blue) with age at Visit 1. “gd T cell” stands for γd T cell. (c) Scatter plots depict centered log ratio (CLR) transformed proportions of CD14+CD16+ monocytes and naïve CD8 T cells as a function of age. P values were calculated using linear modeling with Benjamini-Hochberg correction.
