PPI network and functional enrichment analysis of differentially expressed interleukin genes in AD. (A) PPI network: Nodes represent differentially expressed interleukin genes between normal and AD groups, while edges represent predicted protein-protein interactions. (B) Enrichment analysis: Bar plots display significantly enriched terms for the differentially expressed interleukin genes across four categories (BP, CC, MF, and KEGG)
