The immunologic gene sets revealed the top 3 significantly enriched immune-related gene sets were for the signature characteristics of genes upregulated in response to trivalent inactivated influenza (TIV) vaccination (NES = 1.73; FDR =0.055); genes downregulated in HEK293 cells at 2 h after stimulation by muramyl dipeptide (NES = 1.71; FDR =0.090); genes upregulated in regulatory T cells due to altered function of FOXP3 (NES = 1.71; FDR =0.078). Here, FOXP3 is linked to influenza.
