Figure 4. The potential risk genes and immune changes in Alzheimer’s disease. (A) Four data sets were used to verify the expression of the potential AD risk genes. (B) The AUC value of potential risk genes in AD patients. (C) The 24 differentially expressed immune cells. (D) Correlation between the potential AD risk genes and immune cells. (E) The GSEA results of gene expression in AD patients. (F) Gene expression of AD patients involved in the GSEA KEGG pathway.
