Signal peptide peptidase-like 2b modulates the amyloidogenic pathway and exhibits an Aβ-dependent expression in Alzheimer's disease. KU Leuven
Alzheimer's disease (AD) is a multifactorial disorder driven by abnormal amyloid β-peptide (Aβ) levels. In this study, we investigated the role of presenilin-like signal peptide peptidase-like 2b (SPPL2b) in AD pathophysiology and its potential as a druggable target within the Aβ cascade. Exogenous Aβ42 influenced SPPL2b expression in human cell lines and acute mouse brain slices. SPPL2b and its AD-related substrate BRI2 were evaluated in the ...
