Abstract

- Much is unknown regarding the regulation of Alzheimer-related amyloid-beta protein precursor (A beta PP)-processing in the human central nervous system. It has been hypothesized that amyloidogenic A beta PP-processing preferentially occurs in the regulated secretory pathway of neurons. To test this hypothesis we looked for correlations of A beta PP-derived molecules in cerebrospinal fluid (CSF) with chromogranin (Cg) derived peptides, representing the regulated secretion. Patients with Alzheimer's disease (AD, N = 32), multiple sclerosis (MS, N = 50), and healthy controls (N = 70) were enrolled. CSF was analyzed for the amyloid peptides A beta(1-42), A beta(x-42), A beta(x-40), A beta(x-38), alpha-cleaved soluble A beta PP (sA beta PP alpha), beta-cleaved soluble A beta PP (sA beta PP beta), and peptides derived from CgB and SgII (Secretogranin-II, CgC). We investigated CSF levels of the protease BACE1, which processes A beta PP into A beta, in relation to Cg-levels. Finally, we measured Cg levels in cell media from untreated and BACE1-inhibited SH-SY5Y human neuroblastoma cells. CSF Cg levels correlated to sA beta PP and A beta peptides in AD, MS, and controls, and to CSF BACE1. Cell medium from BACE1-inhibited cells had decreased CgB levels. These results suggest that a large part of A beta PP in the human central nervous system is processed in the regulated secretory pathway of neurons.
