IFNA1 and COVID-19: Using scRNA-seq data performed on nasopharyngeal swabs from 58 healthy and COVID-19 participants from Ziegler et al. 2021 [34], we performed UCell [41] enrichment across all cell types for Reactome IFN signaling pathway [42] to determine immune cell subtypes enriched in IFN signaling and activation in SARS-CoV-2 infection.
