To investigate the dynamic characteristics of memory CD8+ cells in the recovery phase, with a particular focus on the tissue-resident memory CD8+ T subsets (CD8+ Trm), we analyzed scRNA-seq data from GSE186839, which included CD8+ T cells from day 0 (D0), day 7 (D7), and day 14 (D14) after influenza infection. Here, CD8A is linked to influenza.
