GATA3 and influenza: Overall, the expression of GATA3 was low/not expressed in T cells isolated from the assessed sites and was unchanged by TCS exposure (S2 Table) Mirroring the gene expression data, influenza infection resulted in the upregulation of T-bet expression (MFI and frequency/number of T-bet+ cells) in CD4+ and CD8+ T cells compared to uninfected controls (S1 Table).
