Analysis of Immune-related Key Genes in Alzheimer’s Disease

This research revealed that 15 modules were obtained through weighted gene co-expression network analysis (WGCNA), among which the magenta and blue modules were significantly associated with Alzheimer’s Disease (AD). There were 121 genes in the magenta module, and 1022 genes in the blue module. Thro...
