GFAP and Alzheimer disease: Quantification of confocal images from three representative cases of AD patients and matched controls (AD‐V‐VI; n = 100 astrocytes) showed an increased expression of β1‐integrin (Fig 6J,K) and NOX2 levels (Fig 6I,K) (147 ± 24%, and 146 ± 27%, respectively), as well as GFAP protein levels (179 ± 21%), compared to controls (100%) (Fig 6I–K).
