Immune-related genes and differentially expressed immune genes (Imm-DEGs). (A) Arthritis-related differentially expressed genes (DEGs) volcano plot with log2FoldChange in the horizontal coordinate and -log₁₀(Adjust P-value) in the vertical coordinate. Red nodes indicate upregulated DEGs, blue nodes indicate downregulated DEGs, and gray nodes indicate genes that are not significantly differentially expressed. (B) Heat map of arthritis-related DEG expression levels: pink indicates disease samples, green indicates normal control samples, red indicates high gene expression, and blue indicates low gene expression. (C) Immune gene Venn diagram: three colors represent three different data sources. (D) Immune gene versus DEG Venn diagram: pink represents immune genes, green represents DEGs (E) Venn diagram of immune genes and upregulated DEGs: pink represents immune genes, green represents upregulated DEGs. (F) Venn diagram of immune genes and downregulated DEGs: pink represents immune genes, green represents downregulated DEGs.
