The new dataset (dataset 1) [24] was generated using a droplet‐based single‐cell platform (10X Chromium) and contains scRNA‐seq data of CD11c+MHCII+ cells isolated from PBMCs of three COVID‐19 patients (two with mild and one with severe disease) and two HDs (Table S1). This evidence concerns the gene ITGAX and COVID-19.
