We compared the following signatures (significant for GVHD in the previous analyses) in the pre- and post-GVHD onset timepoints: “IFN” (A28 aggregate), “cytotoxicity” (A2 aggregate), “neutrophil” (M15.35), and “neutrophil activation” modules (M10.4 in A38 aggregate) and the “erythroid” aggregate (A37 aggregate) (Figure 5). Here, IFNA1 is linked to graft versus host disease.
