Fig. 4

Visualization of common DEMs in serum, BALF and PBMCs during APP infection. Venn diagram shows DEMs at 0–24 h (A) and at 24–120 h (B). Cytoscape ClueGO analysis identified the link between the common DEMs and its related KEGGs at 0–24 h and at 24–120 h (D). Each cross-node represents a cross-talk gene (different circles indicate signal pathways where DEGs are enriched and genes on branches indicate DEMs involved in the signaling pathway)
