| pubmed-article:16627934 | pubmed:abstractText | The notion that microvascular abnormalities contribute to deleterious changes in the Alzheimer's disease (AD) brain is supported by work from our laboratory and others demonstrating biochemical and functional alterations of the microcirculation in AD. The objective of this study is to determine whether levels of neurotoxic (thrombin) and inflammatory (interleukin 8 (IL-8), integrins alphaVbeta3 and alphaVbeta5) proteins are altered in microvessels isolated from AD patients compared to levels in vessels obtained from non-demented age-matched controls. We also evaluate in AD and control microvessels expression of the transcription factor hypoxia-inducible factor 1-alpha(HIF1-alpha), which regulates pro-inflammatory gene expression, and the regulation of HIF1-alpha expression by thrombin in cultured brain endothelial cells. Our results indicate that in AD there are high levels of expression of the neurotoxic protease thrombin and the inflammation-associated proteins IL-8 and alphaVbeta3 and alphaVbeta5 integrins. HIF1-alpha is higher in AD microvessels compared to control and thrombin treatment of cultured brain endothelial cells results in increased expression of HIF1-alpha. These data suggest that in AD the cerebral microcirculation is a source of neurotoxic and inflammatory mediators and as such contributory to pathologic processes ongoing in the AD brain. | lld:pubmed |
