Several lines of study suggest that peripheral metabolism of amyloid beta (Aß) is associated with risk for Alzheimer’s disease. In blood, greater than 90% of Aß is complexed as an apolipoprotein, raising the possibility of a lipoprotein-mediated axis for Alzheimer’s disease risk. Lam et al. report that genetic modification of C57BL/6J mice engineered to synthesize human Aß only in liver has marked neurodegeneration concomitant with capillary dysfunction, parenchymal extravasation of lipoprotein-Aß, and neurovascular inflammation.
