The results indicated that genes from the SS2 infected macrophages were most significantly enriched in the M1_IFNγ + LPS set, genes from the PPRSV, ASFV, Mhp, and LPS infected were most significantly enriched in the M1_GM-CSF, genes from the PCV2 and T. gondii Me49 infections were most significantly enriched in the M2_M-CSF set, and genes from the different species of T. gondii infections were most significantly enriched in the M2_IL4 + IL10 set (Figure 3). Here, CSF2 is linked to infection.
