TNF and Alzheimer disease: The GFAP+IL-1β+ or GFAP+TNF-α+ or GFAP+IL-6+ expression in cells was increased in the AD group (average 29.4 of CA1 and 34.6 of DG for IL-1β, 48.6 of CA1 and 35.0 of DG for TNF-α, and 35.2 of CA1 and 28.2 of DG for IL-6), compared with Control (average 15.2 of CA1 and 20.2 of DG for IL-1β, 29.2 of CA1 and 22.0 of DG for TNF-α, and 12.4 of CA1 and 10.6 of DG for IL-6), and NS (average 15.6 of CA1 and 20.8 of DG for IL-1β, 32.4 of CA1 and 21.0 of DG for TNF-α, and 12.2 of CA1 and 12.8 of DG for IL-6) groups (p < 0.05).
