Figure 2From: The systemic iron-regulatory proteins hepcidin and ferroportin are reduced in the brain in Alzheimer’s disease Hepcidin protein present in glial cells. In control brain sections from mid temporal gyrus (MTG) hepcidin expression was in astrocytes and co-localised with GFAP ( white arrow, a-d ). Hepcidin was visible in red blood cells close to blood vessels (e). Similarly in MTG in white matter tract hepcidin co-localised with myelin basic protein (MBP), suggesting that hepcidin protein is expressed in oligodendrocytes as well as in astrocytes (f-h). Scale bar panels a-c and e 30 μm, d 15 μm, f-h 20 μm. i. Hepcidin protein levels in the human superior frontal gyrus (SFG) of AD brains compared to controls. Densitometric measurements of corrected total cell fluorescence adjusted against background (n=20, p<0.0001). j. Ferroportin protein level in human SFG of AD brain compared to controls (n=20, p<0.0001) k. Hepcidin protein level in the dentate gyrus of APP-tg mice vs control (n= 20, p<0.0001). ***denotes p<0.0001.Back to article page
