Fig. 4. Profound inflammation in AD.
RNA from peripheral blood of AD patients (n=9) and healthy controls (n=10) were assayed by genome-wide gene expression microarrays. Significantly altered genes (≥2-fold FDR≤1%) detected by microarrays in AD blood were analyzed for functional association, using IPA. a. Heat maps on immune gene alterations (273 gene) were generated using MeV analysis software: AD1–9: AD patients; C1–10: healthy controls; Red: up-regulated genes in AD; Green: down regulated genes in AD; Color intensity: degrees of changes. b. Functional interactions of significantly altered immune genes associated with AD neuropathology were identified using IPA: solid line: direct relationship; dash line: secondary relationship. *Gene symbols and the direction of gene alteration are shown Supplementary Table S2.
