We noted that the type I IFN gene transcripts were mainly derived from microglia and monocytes, as well as the very low-abundant plasmacytoid dendritic cells, peaking on day 4, while a strong Ifng expression (type II IFN) was observed throughout the time of the infection from NK cells and T cells (Fig. 2E; Fig. S2G). This evidence concerns the gene IFNG and infection.
