The accessible cerebral vascular proteome in a mouse model of cerebral β-amyloidosis

2011 
Assessing protein changes in the cerebral vasculature of brain disorders may increase our understanding of disease pathogenesis and facilitate diagnostic and therapeutic intervention. By combining perfusion of mice with a charged reactive biotin derivative and subsequent quantification of the biotinylated proteins, the proteome accessible from the vasculature in an APPPS1 transgenic mouse model of cerebral β-amyloidosis was identified and compared to that in non-transgenic control mice. Our results provide proof-of-concept of this technology for the identification of new targets for antibody-based therapy or pharmacodelivery, and for neuroimaging in neurodegenerative diseases.
