While classical NEC appeared more heterogeneous in this analysis, DEGs (Figures 5A and S11C) used to construct the largest PPI subnetwork (Figure 5B) largely functionally mapped to dopamine signaling (Figure 5C), similar to those comprising differentially enriched pathways in the CD45+ analysis (Figures 3E and 3F). Here, PTPRC is linked to necrotizing enterocolitis.
