Transcription levels of the myeloid-associated genes C/EBPα, PU.1, FOG1, and G-CSF were increased in total BM cells by 2–3-fold at 12 h post infection (Figure 5 left panel), while transcription levels of the lymphoid-associated genes IL7-R, Flt3, Rag1, PAX5, and Ikaros did not change at this time point (Figure 5 right panel). Here, SPI1 is linked to infection.
