Activation Of Matrix Metalloproteinases Following Anti-Aβ Immunotherapy; Implications For Microhemorrhage Occurrence, Donna M. Wilcock, Dave Morgan, Marcia N. Gordon, Tiffany L. Taylor, Lisa A. Ridnour, David A. Wink, Carol A. Colton

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Anti-Aβ immunotherapy is a promising approach to the prevention and treatment of Alzheimer's disease (AD) currently in clinical trials. There is extensive evidence, both in mice and humans that a significant adverse event is the occurrence of microhemorrhages. Also, vasogenic edema was reported in phase 2 of a passive immunization clinical trial. In order to overcome these vascular adverse effects it is critical that we understand the mechanism(s) by which they occur.

METHODS: We have examined the matrix metalloproteinase (MMP) protein degradation system in two previously published anti-Aβ immunotherapy studies. The first was a passive immunization study in which …

While the presence of an inflammatory response in AD (Alzheimer's disease) is well known, the data on inflammation are conflicting, suggesting that inflammation either attenuates pathology, exacerbates it or has no effect. Our goal was to more fully characterize the inflammatory response in APP (amyloid precursor protein) transgenic mice with and without disease progression. In addition, we have examined how anti-Aβ (amyloid β-peptide) immunotherapy alters this inflammatory response. We have used quantitative RT–PCR (reverse transcription–PCR) and protein analysis to measure inflammatory responses ranging from proinflammatory to anti-inflammatory and repair factors in transgenic mice that develop amyloid deposits only …
