(A) Schematic highlighting design of stimulation experiment. Human peripheral blood mononuclear cells (PBMCs) were stimulated with DMSO control, lipopolysaccharide (LPS), interferon gamma (IFN-Ɣ), or phorbol myristate acetate (PMA) plus ionomycin for 1 or 6 h with or without a Golgi inhibitor (GI) for the 6-h treatment condition. Cells were then split and profiled using scATAC-seq and scRNA-seq for each condition and time point considered.
(B) Total number of cells profiled per condition passing quality control filtering for scATAC and scRNA-seq.
(C) Uniform manifold approximation and projection (UMAP) of scATAC-seq cells based on latent semantic indexing (LSI) dimensionality reduction, with cells colored by treatment condition.
(D) UMAP of scRNA-seq cells based on principal-component analysis (PCA) dimensionality reduction, with cells colored by treatment condition.
(E) UMAPs of scATAC-seq cells (top) and scRNA-seq cells (bottom), highlighting individual conditions under control (6 h) and PMA (1 and 6 h) conditions.
(F) Aggregate accessibility profiles for scATAC-seq monocyte cells around genes IFITM3 and HES4.
(G) Distribution of single-cell expression levels based on the imputed scRNA-seq counts for stimulation-specific gene markers shown in (F) per condition for scRNA-seq monocyte cells.
