- INTRODUCTION Amyloid-beta (A beta) and tau can be quantified in blood. However, biological factors can influence the levels of brain-derived proteins in the blood. The blood-brain barrier (BBB) regulates protein transport between cerebrospinal fluid (CSF) and blood. BBB altered permeability might affect the relationship between brain and blood biomarkers.METHODS We assessed 224 participants in research (TRIAD, n = 96) and clinical (BIODEGMAR, n = 128) cohorts with plasma and CSF/positron emission tomography A beta, p-tau, and albumin measures.RESULTS Plasma A beta(42/40) better identified CSF A beta(42/40) and A beta-PET positivity in individuals with high BBB permeability. An interaction between plasma A beta(42/40) and BBB permeability on CSF A beta(42/40) was observed. Voxel-wise models estimated that the association of positron emission tomography (PET), with plasma A beta was most affected by BBB permeability in AD-related brain regions. BBB permeability did not significantly impact the relationship between brain and plasma p-tau levels.DISCUSSION These findings suggest that BBB integrity may influence the performance of plasma A beta, but not p-tau, biomarkers in research and clinical settings.
