Flowchart of the study. Microarray data from whole peripheral blood of patients with Alzheimer’s disease (AD) or ischemic stroke (IS) were obtained and analysis for differentially expressed genes (DEGs) between patients and healthy controls was performed. Protein-protein interactions network (PPI–Net), drug targets, functional enrichment, and immune infiltration analysis were applied to common DEGs between AD and IS, to explore shared mechanism between these two diseases. Hub genes obtained by PPI-Net analysis and potential drug targets were validated with test dataset of AD and IS.
