sAPP-alpha, Transthyretin, and Neuroprotection
Publish Date : 9/2/2004 1:16:00 PM Source : SkinCareIndia Health News
The accumulation of beta-amyloid in Alzheimer's disease (AD) is only one of the results of proteolytic cleavage of amyloid precursor protein (APP).
Cleavage by beta- and gamma-secretase leads to A-beta production, whereas alpha-secretase cleavage results in a soluble form, sAPP-alpha.
This week, Stein et al. examine the apparent neuroprotective role of sAPP-alpha in mice.
Using antibody interference and siRNA knockdown techniques, the authors demonstrate, in hippocampal slices and in vivo, that sAPP-alpha provides the mutant mice with the protective armor of increased TTR and IGF-2 expression, thus preventing tau phophorylation and neuronal death. Too bad that sAPP-alpha is not at high levels in Alzheimer's patients.
