GATA3 and infection: In addition, we evaluated the relative expression of transcription factors involved in T-cell differentiation, namely T-bet (for Th1 cells), GATA-3 (for Th2 cells), and ROR-γt (for Th17 cells) and found that the three transcription factors at days 3, 7, and 14 post-infection were similarly expressed in WT and gal3−/− mice (Fig. 5).
