Gene set enrichment analysis (GSEA) revealed that FcεR1γ-deficient ILC3s exhibited reduced expression of genes enriched in multiple immune activation pathways, including cytokine-cytokine receptor interaction, JAK-STAT signaling and chemokine signaling pathways (Supplementary Fig. S5F), all of which were induced by the infection in WT ILC3s (Supplementary Fig. S4F, G). This evidence concerns the gene SOAT1 and infection.
