APP dimer formation is initiated in the endoplasmic reticulum and differs between APP isoformsSimone Isbert

Cell Mol Life Sci 69:1353-75. 2012..Thus, suggesting that steric properties of KPI-APP might be the cause for weaker cis-interaction in the ER, compared to APP695. Finally, we provide evidence that APP/APLP1 heterointeractions are likewise initiated in the ER...
FE65 constitutes the functional link between the low-density lipoprotein receptor-related protein and the amyloid precursor proteinClaus U Pietrzik

Department of Neurosciences, University of California, San Diego, La Jolla 92093, USA
EMBO J 21:5691-700. 2002..Therefore, we propose a model by which LRP functionally modulates APP processing, including those steps critical for Abeta production, through interactions of the cytosolic domains...
Mechanisms of C-reactive protein-induced blood-brain barrier disruptionChristoph R W Kuhlmann
Institute of Physiology and Pathophysiology, Johannes Gutenberg University of Mainz, Mainz, Germany
Stroke 40:1458-66. 2009..The aim of this study was to examine whether CRP directly affects blood-brain barrier stability and to analyze the underlying signaling pathways...
Sequences from the low density lipoprotein receptor-related protein (LRP) cytoplasmic domain enhance amyloid beta protein production via the beta-secretase pathway without altering amyloid precursor protein/LRP nuclear signalingIl Sang Yoon
Department of Neurosciences, University of California, San Diego, La Jolla, 92093, USA
J Biol Chem 280:20140-7. 2005..These observations indicate that there are cellular pathways that may suppress Abeta generation but that can be altered to facilitate Abeta production...
Blood-brain-barrier models for the investigation of transporter- and receptor-mediated amyloid-β clearance in Alzheimer's diseaseT Pflanzner

Amyloid precursor-like protein 1 influences endocytosis and proteolytic processing of the amyloid precursor proteinStephanie Neumann
Adolf Butenandt Institut, Ludwig Maximilians University, Schillerstrasse 44, 80336 Munich, Germany
J Biol Chem 281:7583-94. 2006..In summary, our study provides a novel mechanism for APP shedding, in which APLP1 affects the endocytosis of APP and makes more APP available for alpha-secretase cleavage...
Increased AICD generation does not result in increased nuclear translocation or activation of target gene transcriptionElaine Waldron
Institute of Physiological Chemistry and Pathobiochemistry, Molecular Neurodegeneration, Johannes Gutenberg University Mainz, 55099 Mainz, Germany
Exp Cell Res 314:2419-33. 2008..Therefore we provide strong evidence that an increase in AICD generation does not directly promote gene activation of previously proposed target genes...

Department of Neuropathology, University of Bonn, Bonn, Germany
J Neuropathol Exp Neurol 67:842-56. 2008..It is therefore tempting to speculate that apoE represents a pathogenetic link between SVD and AD...
