Fig. 4From: Neuroprotection in early stages of Alzheimer’s disease is promoted by transthyretin angiogenic propertiesEffect of TTR reduction on collagen IV levels, in NT and AD mice. Representative images and quantification plots of collagen IV (red) immunostaining depicting microvessels of NT/TTR+/− (n = 4) and AD/TTR+/− (n = 5) 3-month-old mice in cortex and hippocampus, showing an increase in collagen IV expression in AD/TTR+/− mice relatively to NT/TTR+/− littermates, in the hippocampus. Data are expressed as mean ± SEM. *p < 0.05. Scale bar = 5 μmBack to article page
