In sporadic age-related forms of Alzheimer’s disease (AD), it is unclear why amyloid-β (Aβ) peptides accumulate. Here, we show that soluble amyloid precursor protein-α (sAPP-α) decreases Aβ generation by directly associating with BACE1; thereby modulating APP processing. Whereas specifically targeting sAPP-α using antibodies enhances Aβ production, in transgenic mice with AD-like pathology, sAPP-α overexpression decreases β-amyloid plaques and soluble Aβ. In support, immunoneutralization of sAPP-α increases APP amyloidogenic processing in these mice. Given our current findings, and because a number of risk factors for sporadic AD serve to lower levels of sAPP-α in brains of AD patients, inadequate sAPP-α levels may be sufficient to polarize APP processing toward the amyloidogenic, Aβ-producing route. Therefore, restoration of sAPP-α or enhancement of its association with BACE may be viable strategies to ameliorate imbalances in APP processing that can lead to AD pathogenesis.
